I will start my job back in talking about the finger joint program on which Stark in recent years has spent a lot of resources to achieve important goals such as having a high market share in the knowledge that paid off with strong competitors. I personally in my role as area manager in Italy have reached important goals to become the first official supplier of the leading Italian manufacturers ( OMGA, SPANEVELLO,CM, PAOLETTI ) among whom I have also managed to get a deal directly with Weinig to equip all machines sold in Italy. This has allowed me to and Stark to consolidate and improve its product thanks to the fact of selling directly to end users will come to a major market share to about 80% finger joint Italian manufacturers. Thanks also to the export of machines manufactures we got good market share abroad, especially in the countries of Eastern Europe and Russia. This success has made it necessary to make use of a large automation in production, mainly of knives which allowed us to ensure delivery as well as a more dynamic also a good consistent product performance and then, thanks to the study of new geometries that allowed Profile to be more powerful and guarantee of performance never before achieved. We have also further improved the coatings used and the last has a very low coefficient of friction against. Even the complaints have fallen dramatically and this has allowed us to obtain a product as well as more performance even more competitive prices it so you can be more competitive in the market against competitors who still use the old technologies that seemed brazed tools more competitive. While being able to offer a product superior to those currently in use (STHELE, LEITZ, LEUCO) our future strategy will be to sell our product to a price level very close to that of the brazed tools for finger joint so as to maximize the convenience that unlike the brazed tips when finished will just replace the knives only and not any element with a significant and additional savings in the economic management of the product As you already know the advantage of using interchangeable knife is very high and not spend more words. We have also placed much attention on information to be given to customers on sharpening so as not to create conflict situations unsuitable for operations that created many problems and disputes, and we had a brochure ( pdf attached 1) with some suggestions that we want to further implement. Aware that the new machines do not like heavy weights and to avoid giving this advantage to the brazed tools we were able to significantly reduce the weights of all tools while maintaining both the safety and the mechanical strength of the bodies.


We feel really ready and competitive for all types of joints (vertical and horizontal) and all the products we offer in our offering (TG05 and TG25). We therefore developed specific programs for any type of machine in order to facilitate the choice of the tool best suited to our partners This success has enabled us not only to consolidate our relationship with our partner, also find new products, making this one of our BEST SELLERS. This important sector has also enabled us to develop even planing the beams with a significant improvement of hydro blocks and especially of the planers PLANNEX particularly suitable in saw milling plants in the construction of ecological houses and X LAM plants. I am therefore willing to refresh the topic again so that you too can benefit from this great product development. Especially for TURBO S and CombiPact Weinig plants we have studied tools with a high number of teeth to provide great returns to high feed achieving important successes.

TG05FC

Testa portacoltelli in acciaio ad alta resistenza a 4, 6 o 8 taglienti per eseguire giunzioni tipo “finger” - “minizinken”. Si tratta di un utensile componibile che permette di utilizzare più teste a seconda dello spessore del legno da lavorare. I coltelli sono intercambiabili e a profilo simmetrico. Le dimensioni delle giunzioni ottenibili sono: 4 mm, 4,5/5 mm, 10/10 mm, 10/11mm, 15/15 mm, 15/16,5 mm, 20/20 mm e 20/22 mm. I coltelli sono prodotti in HS trattati con un particolare rivestimeno superficiale PVD che ne aumenta la durata fino a un 100% in più e in HW (solo per le dimensioni 10/10 mm e 10/11 mm). Le dimensioni dei coltelli 4,5/5 mm, 10/11 mm, 15/16,5 mm e 20/22 mm sono adatte per lavorazioni su macchine che utilizzano la lama ad intestare e su impianti specifici. L’utensile è adatto per eseguire giunzioni per utilizzi differenti, dalla produzione di profili lamellari in legno per serramenti ai semilavorati per arredamento. Con i profili più profondi (20/20 mm e 20/22 mm) si ottengono giunzioni per strutture portanti in legno lamellare (norme UNI 8922, DIN 68140 e DIN 1052), particolarmente adatte per grandi luci quali impianti sportivi, capannoni industriali, aree espositive, ponti ecc. In fase d’ordine specificare il tipo di macchina sulla quale gli utensili saranno montati. Finger joint cutterhead body in high tensile steel with 4, 6 or 8 knives for manufacturing “minizinken” style finger joints. The tool can be stacked based on the wood thickness to be cut. The knives are interchangeable and have a symmetrical profile. The following joints are available: 4 mm, 4,5/5mm, 10/10 mm, 10/11 mm,15/15 mm, 15/16.5 mm, 20/20 mm and 20/22 mm. The knives are manufactured in solid HS with special PVD surface coating for longer tooling life (up to 100% increase). Profiles 4,5/5 mm, 10/11 mm, 15/16.5 mm and 20/22 mm are specific for butting machines. The tool is suitable for use in various fields: laminar profiles, window frames, furniture, etc. The deepest profiles (20/20 mm and 20/22 mm) are appropriate for laminar structural elements in the building field (DIN 68140 and DIN 1052 specifications). When ordering specify the type of machines on which the tool will be mounted. Anwendung: Zinkenprofile als Längsverbindung in Weich- und Harthölzern für hochbeanspruchte Teile im Ingenieur-Holzbau (DIN 1052), sowie im Fensterbau, in der Fußboden- und Leistenfabrikation. Es werden je nach Holzstärke ein oder mehrere Fräser eingesetzt. Technische Daten: 4, 6 oder 8 gerade liegende, auswechselbare HS-Schneiden, welche auf Wunsch mit PVD-Beschichtung geliefert werden können oder HW-Schneiden (achsparallel). Profil gerade hinterschliffen. Höhenverstellung für Gegenprofil = Teilung. Durch die auswechselbaren Segmente kann leicht eine Beschädigung der Schneiden behoben werden. Daher ist es nicht mehr notwendig, die guten Schneiden bzw. den ganzen Fräsersatz nachzuschleifen. Exakte Werkstückspannung und spielfreie Werkstückführung erforderlich. Durch die spezielle Konstruktion der Fräskörper ist der Minizinkensatz beim Abbremsen der Maschinenspindel gegen Verdrehen gesichert. Dadurch treten keinerlei Beschädigungen am Körper und an den Schneiden auf. Bei Bestellung bitte angeben auf welcher Maschine die Fräser verwendet werden.

In sharpening with the tools package must be mounted be very careful alignment of the blades through a steel ground bar on which will be positioned appropriately in support of all the knives on the chest (in most grinders in use) resulting in alignment of the wheel a perfect parallel to the chest of the teeth. This positioning should be done only the first time and then the divisor will be used (4 or 6 divisions) Individually made in sharpening the parallelism between the chest and the knife wheel is found through the use of the probe. The probe after verifying the correct position (parallel) looks for points by measuring the angle of attack in order to store the average for the next tool position. This positioning should be done only the first time and then the divisor will be used (4, 6, 8 or 9 divisions).

Respect the limits of safety with respect to the number of sharpening (Article CGMZ0S max 9 mm max 3.5 mm inserts 600731-600732) Respect the time of sharpening! Remember that means having to exaggerate more sharpening the tooth, jeopardizing his life and obviously risking breakage Let us remember that the breaking of a tooth will cause not only damage to the knife that comes but may even cause the breakdown of many other teeth as the shards of the knife will be put into rotation within the housing going to affect the other knives and causing breakage. Sharpening is a very important factor properly to get a good finger joint .. If the cutting angle of the cutter changes, there will be a corresponding change in the profile In general, you can run 2-4 shifts between sharpening, The grinding wheel used will have a great influence on cutting performance. A 80 grit to 1700 RPM usually excellent results on HSS drills. Depending on your sharpening techniques, you can have more success with a wheel diameter of 120-150 mm. The lot for the sharpening of cutters will be HS CBN (cubic boron nitride) Once the head is mounted on the grinder, the cutter to score the chest with a marker. This will indicate whether you are making contact with all the drills in a package. Be sure to remove only 0.005 mm. in each step, and always be sure that the grinding is sufficient to remove all signs of wear and chipping areas. It 'very important to sharpen the top corners of the drills until the surface of the cutting edge is "clean" And' possible to have a cut that seems to be good, but closer examination shows the wear in the upper corners. This condition prevents a good clean cut, and can help you rip. A micro finish of 50 RMS or better will give best results

This procedure is conditioned by many factors such as speed, the spindle speed, the species of timber, the type of machine used and types of joints to be cut. The length of the joint determines when the equipment is to be reground. The length of the joint ZL increases as the tip of the tooth "check". If the measured length on the wood is more than 20% more than the length specified, the tool must be reground. Other drawbacks are an excessive tearing, rip-outs and excessive chipping. Intervals recommended maintenance procedures are as follows: Sharpen cutters every 1 - 3 rounds, or if necessary, depending on conditions Align sharpener sharpening every ten times Stark also recommended to have an archive where you can keep all the operations performed on the heads. STEP 1 Clean tools using Technichem or similar liquid cleaner . You may need to remove the knife from the head and clean thoroughly if there is excessive accumulation of resin, rust or corrosion present. Never use abrasives to clean the knives and cutters. STEP 2 The most common method for sharpening the heads is described below. The tool life is about 1 to 3 rounds (28,000 to 90,000 joints cut for Z = 4 / 6). STEP 3 Using a marker, on each side of the knife, this will allow you to see how the wheel works. Select-a series of heads lined up as a starting point. Align-knives with a grinding wheel spindle and turning the head to align the wheel Optimize alignment with the vertical (Z) and horizontal (X) -The wheel must be perfectly aligned with the knife, giving a very precise point of departure in order to maintain the correct angle. Run the set-up by removing material only 0.01 mm, with 2 to 3 passes Inspect the blades and see if the ink from the marker was removed uniformly on each knife. Otherwise, make the adjustments required alignment and run 2-3 more passes with no more than 0.01 mm. material removal. If the consistent look, you will be removed from 0.15 mm to 0.20 mm. in total for each knife. 4 steps have been carried out in total.

REVERSIBLE By far the most common joint. Requires two heads; one with thick cutter at top of stack and one with thick cutter at bottom of stack. This joint may also be achieved on a single head shaper by reversing alternate pieces of stock machined.

MALE-FEMALE OR END MATCH Less common joint than reversible. Always requires two heads; one with all thin cutters and one with a thick cutter at both top and at bottom of stack.

Special joint with thick cutter at center of stack to allow for finger jointed stock to be split or re-sawn into two pieces.

SCARF OR FEATHER JOINT Usually requires no thick cutters. Used when dimensions of stock will vary significantly.

Structural Because of their exceptional strength, finger joints are utilized in a multitude of load bearing applications including laminated beams, I-beams, and a variety of other structural components.

Sub-Structural Typical applications for finger jointed sub-structural lumber include pallets, dimensional construction lumber (i.e. 2x4, 4x4, etc.), overhead door parts and furniture.

Non-Structural Non-structural finger jointed products consist of door and window mouldings, doorjambs, cores, casings, interior trims, and shelving material. These operations benefit from the recovery of scrap lumber and from the upgraded clear lumber produced.

Specialty Finger jointing keeps growing in the specialty wood products market as hundreds of specialty manufacturers realize the great financial returns possible from finger jointing. Specialty finger jointed products include curtain rods, tooth pick and pencil stock, cutting boards, toys, round top windows, floor material, as well as many other products.

Vertical Common in Europe and Asia, vertical finger joints are used in a variety of wood products - most commonly in furniture and components. With the introduction of the TG25 finger joint system, STARK can now offer a precision vertical tooling option.

STARK FINGER JOINT CUTTERS STARK finger joint cutters are the ultimate in quality and cutting precision. Our cutters are manufactured using German Iron and Steel We do not cast or injection mold our cutters. Using advanced statistical process control and inspection procedures, our skilled workforce produces the most uniform, high-quality cutters on the market today. STARK maintains a large volume of standard production cutters that can be shipped overnight if needed. We also have the capability of producing custom cutters to meet your specific requirements. Some of the innovations pioneered by STARK include micro joints that save lumber, special cutter treatments that reduce downtime, and our new TG25 Vertical and horizontal Finger Joint System.

TG25 HW INSERTS AND TG05 HS INSERTS Thickness accuracy and flatness are the key elements that guarantee cutter stacks will meet finger joint tolerance expectations. Through research and process evolution, STARK has developed disposable inserts - a process that achieves new levels of flatness and accuracy far exceeding current industry standards. Thickness Accuracy disposable inserts guarantees thickness accuracy tolerances to be held to under ± 0,01 mm. , which is at least twice as accurate as other manufacturer’s cutters. The inserts eliminates many of the tolerance accumulation problems associated with stacked cutters and ensures that all cutters follow the same tracking plane.

Flatness Inserts produces cutters so flat they actually adhere to each other. When two STARK cutter faces are pressed together with a slight twisting motion, essentially all the air between them is compressed out, and a vacuum is formed. This physical law can only be obtained with flatness tolerances below ±. 0,012mm disposable inserts also improves the remaining physical dimensions of the cutters, because the inserts surfaces are used in subsequent processes as critical location surfaces. Inserts cutters compress better, have tighter tolerances, and produce more consistently accurate wood joints.

CUSTOM PROFILES In addition to the stock cutters listed previously, has designed and manufactured scores of other finger joint configurations. Our Engineering files contain hundreds of profiles. Many of these profiles were developed as the result of close work between a user and our engineers. From micro joints to large structural joints, if a standard profile is not suitable for your application, engineers will assist in the development of a finger joint profile to get the job done.

CUSTOM CUTTER MATERIALS M-2, Carbideare used in the majority of applications, however, difficult and unusual applications are welcomed PVD tool steel, high cobalt alloys, and other materials may be the answer for you. As always, engineers are your best source of information here. Whether your needs are for a specific finger joint profile, a custom designed cutterhead to fit your machine, or a cutter material to machine a particularly hard or abrasive wood product, has the technical support that you need.

Finger joint system

GI05,TG05 and TG25 STARK FINGER JOINT SYSTEM Designed specifically for vertical-style finger joint machines, the innovative STARK system represents a significant leap forward in vertical finger jointing technology. STARK has utilized all of our advanced capabilities to design a vertical system that offers: l l l l l

High Precision Cutting Ease of use Versatility Economical Operation Longer Cutter Life

STARK System is designed to accommodate smaller cutting circles (extreme swing), while maintaining the tight tooling tolerances STARKis known for. STARK system combines also the advantages of hydraulic centering with the convenience of drop-on plates.

Multiple Set-up Options: l l l

Standard Staggered Spiral

GI05 and TG25 Cutter Advantages Disposable inserts Flatness and Thickness The cutters are precision ground using our inserts process to ensure thickness accuracy tolerance of Âą .0,012 and flatness accuracy of Âą 0.02 mm, which eliminates tolerance accumulation problems associated with other vertical tooling. Better Cutting Circle Retention As the STARK cutters are resharpened, the change in cutting circle is less than conventional vertical tooling. This helps ensure that joint quality is not compromised over the life of the cutter.

Longer Usable Cutter Tip STARK cutter offers a usable cutter length of .4-4 mm., which is nearly twice as much as the 10-11 mm. length for most conventional vertical tooling and 15 -20 mm. for beams Easy, Economical Cutter Replacement If a cutter needs to be replaced, inserts can easily be interchanged one by one. Because cutters can be replaced as individual plates, cost is much lower than some other vertical systems.


STARK

FINGER JOINTING CUTTING CONDITIONS

Cutting conditions that determine the rate of material removal are cutting speed, feed rate, and depth of cut. • Cutting Speed:

The speed at which the cutter passes through the wood.

• Feed Rate:

The speed at which the wood is fed through the cutter head.

• Depth of Cut:

The amount of wood removed when each cutter passes through.

Cutting conditions and the type of material to be cut determine the power required to make the cut. Cutting conditions and tool life are related. Optimum cutting speed and feed rate should be used if longer tool life is expected. Tool life is influenced mainly by cutting speed, then by feed rate, and lastly by the depth of cut. The appropriate cutting speed is a relationship derived from relative hardness, properties of the material doing the cutting, and the material being cut. Most commercial finger jointer machines use specified head sizes and fixed RPM, therefore cutting speeds are set.

CUTTING SPEED These formulas are helpful in establishing cutting speed for materials that are not typical. Cutting Speed Formula - English

V = Cutting Speed (surface feet per minute) = 3.1416 D = Dia. (extreme swing of cutter head in inches) N = Spindle Speed (R.P.M.) Examples: Commercial finger joint machines - English

V=

DN 12

D = 10.5” N = 3,600 R.P.M.

Cutting Speed Formula - Metric V = Cutting Speed (surface meters per minute) = 3.1416 D = Dia. (extreme swing of cutter head in mm) N = Spindle Speed (R.P.M.)

DN V = 1000

Examples: Commercial finger joint machines - Metric D = 250mm N = 4200 R.P.M.

V = 3.1416 x 250 x 4200 = 54,97 m/sec. 60000

D = 250mm N = 5000 R.P.M.

V = 3.1416 x 250 x 5000 = 65,45 m/sec. 60000

D = 170mm N = 6,000 R.P.M.

V = 3.1416 x 170 x 6,000 = 53,40 m/sec. 60000

D = 180mm N = 6,000 R.P.M.

V = 3.1416 x 180 x 6,000 = 56,54 m/sec. 60000

Note: The above chart shows Marks per Millimeter (M.P.mm.) and chip load, with the figures in parenthesis indicating chip load. The chart shows ideal average ranges. Some long joints and certain species of wood will require a different M.P.mm. or feed rate. 1.8 to 2.6 M.P.mm. is ideal for most conditions.

M.P.mm =

R.P.M x Z 1000 x Feed Rate in Meters/Min.

Packet style finger joint machines use somewhat different feed rates for cutting through lumber. A packet style machine will have several boards stacked together and clamped as they are machined by the tooling. Therefore, the finger joint cutters are generally in solid wood longer than a chain fed machine (one piece at a time). Feed rates on packet machines are generally higher, so the heat build-up in the tooling is kept to a minimum. However, higher feed rates decrease the Marks Per millimeter which will increase the cutting pressure by increasing the Chip Load. A typical feed rate for a packet machine ranges between 0.98 to 1.38 Marks Per Millimeter which results in a chip load ranging from 0.72 mm to 1.02mm.

CHIP LOAD

Chip load is defined as the amount of material removed by each cutting tooth or edge with each revolution of the spindle. By calculating chip load per cutter, we can determine how hard the cutters are working within the cutter head and provide a benchmark on the range of force that is applied from each cutter to the lumber itself. As chip load increases, tool pressure and heat will increase. Both of these factors increase the rate of wear on the cutting face of the cutter, thus reducing the operating time between sharpenings. Increased chip load will also contribute to excessive tear-out because of the elevated tool pressure. As chip load decreases, tool pressure and heat will decrease. If chip load is reduced too much, the cutters will just rub rather than cut an efficient chip. This excessive friction dulls the cutting edge prematurely and could possibly burn the wood enough to “seal” the wood from glue penetration. This rubbing still requires significant horsepower, but the chip load to horsepower ratio is inefficient. To calculate chip load per cutter use the following formula: Chip Load (English)=

Feed Rate (Feet per minute) x 12 Number of Cutters x R.P.M.

Chip Load (Metric)=

Feed Rate (Meters per minute) x 1000 Numbers of Cutters x R.P.M.

Chip loads can be compared to one another only if the joint length and geometry are the same. The same chip load will remove a greater area of wood for a longer joint than for a shorter joint. The figure below illustrate the effect feed rate has on chip load. Feed rate must be adjusted to achieve the recommended chip load range. Recommended chip load range fr horizontal joint = .015” to .021” (0.38mm to 0.53mm) for optimum tool life. Recommended chip load range fr vertical joint = 0,72 mm to 1,02 mm. for optimum tool life Some chip loads can be as small as .015” (0.38mm) without producing any burning of wood, dulling of cutters, or tear-out. Generally, this is common for machines with small cutting circles or low cutting speeds.

FINGER JOINT TOOLING MAINTENANCE - GRINDING MACHINE

Maintaining your STARK finger joint tooling is critical to the success of your finger joint operation. This section provides the necessary information needed to keep your STARK tooling performing at its peak and includes step-by-step procedures for: 1b Sharpen until corners are full. • Preparing a Finger Joint Head Original edge • • • • • •

Setting up the Head Using a Single or Multi-post Stand Properly Torquing the Head Aligning the Grinding Machine Sharpening Finger Joint Cutters Proper Grinding Wheel Use Maintaining Cutting Angle and Gullet Cutter Tip Fig. 1b

How often you perform these procedures is dependent on many different factors. In particular, resharpening rates are influenced by many factors including feed rate, spindle RPM, species of lumber being finger joint ed, type of machine used and types of joints being cut. Joint length also determines when the tooling needs to be resharpened. Joint length increases as the cutter edge dulls. If the measured joint length is more than 20% longer than the specified length, the tooling needs to be resharpened. Other common signs of dull cutters include excessive tear-out, rip-out, or joints that splinter excessively. Recommended intervals for the maintenance procedures are: • Sharpen Cutters: Every 1 to 3 shifts, or as needed depending on conditions • Align Grinding Machine: Once every ten uses • Post on Setup Stand:

After every 5 resharpenings, or when the cutters are 0.025 inches away from the alignment post

STARK also recommends that you maintain a logbook for keeping records of all maintenance performed on the cutters and heads.

STEP 1 - PREPARE FINGER JOINT HEADS If head is new, clean all cutter mating surfaces on the index and around the cutter bolt hole, and then proceed to balancing cutters. If head has been used, clean tooling using Technichem Blade Clean. For tooling that is relatively clean, proceed to posting on the set-up stand. For heavy pitch buildup, use medium grade Scotch-Brite to clean. It may be necessary to remove the cutters from the head and clean thoroughly if there is excessive pitch buildup, rust or corrosion present. Never use abrasives to clean cutters or the cutter head.


STARK

JOINT LENGTH ADJUSTMENT

JOINT LENGTH ADJUSTMENT There are three stages of cutter edge wear that require joint length to be adjusted.

CUTTER

1st STAGE Sharpening creates a burr on the cutter edge. This burr cuts a wider interior tip. The exterior tip must be wider to match, so the joint is shortened. Do not attempt to deburr cutting edge as dulling of cutters will result.

WOOD

CUTTER

2nd STAGE The edge smooths out as the burr wears off and interior tip width is reduced. Joint is lengthened to match the thinner exterior tip. This stage is the majority of run time

WOOD

CUTTER

3rd STAGE The cutter edge dulls. Interior tip is thinner, so the joint is lengthened again to get thinner exterior tip. This stage indicates cutters need to be resharpened.

WOOD

Length adjustment is normally accomplished with a trim saw.

FINGER JOINT TROUBLE-SHOOTING

PROBLEMS FROM IMPROPER CUTTER BEVEL in the section on cutter grinding, the incorrect bevel on your cutter face is indicated by the grinding template. Great care must be taken to be sure that the correct cutter angle is maintained as the incorrect angle may produce the problems shown below.

CUTTERS GROUND TOO SHARP If the bevel on the cutters is ground too sharp, as shown, the joint produced may be characterized by fingers that are concave. This situation will produce a joint that will either not glue up correctly, or one that will be visibly loose.

CUTTERS GROUND TOO BLUNT If the bevel on the cutters is ground too blunt, as shown, the joint produced may be characterized by fingers that are convex. This situation will produce a joint that is very tight or difficult to assemble.

CUTTERS GROUND CORRECTLY If the bevel on the cutters is ground correctly as shown, a good fitting joint will be the result, as long as the trim saws are correctly set up. See following page for trim saw set up.


STARK

FINGER JOINT TROUBLE-SHOOTING

PROBLEMS FROM MIS-ALIGNMENT OF CUT OFF SAW Correct setting of the cut off saw is crucial for a good fitting finger joint. The overall length of the fingers is extremely critical as well as whether the saw is running true and cutting a good square end. Following are some common problems and how the joint will be affected.

FINGERS TRIMMED TOO SHORT When the trim saw removes too much material from the end of the stock, the joint will be tight at the sides of the fingers before the fingers are able to reach the bottom of the joint. This condition is shown at the right and it is noted that there is visible space at the end of the fingers while the sides of the joint are in contact with each other. The saw must be adjusted so that the resulting fingers are longer.

FINGERS TRIMMED TOO LONG

FINGERS TRIMMED CORRECTLY When the trim saw is set so that it leaves the correct length finger, a good fitting joint is possible. Always be sure that the cutters themselves are correctly ground (see preceding page) or a poor joint will result.

FINGER JOINTS

When the trim saw is set so that it leaves too much material, the resulting joint “bottoms out” before the sides of the fingers are in contact with each other. Remember that unless you are using a special head equipped with trim knives, the fingers themselves are not cut on the ends by the heads. The trim saw must be set accurately to ensure the perfect fit.

FINGER JOINT TROUBLE-SHOOTING

JOINT OPEN ON ONE SIDE This problem is evidenced by a tapered opening on the face of the wood. In addition, there will be tip thickness variations from one side to the other. This is usually caused when the wood is allowed to move during the cut, or when the wood is not fed squarely.

OPEN

Wood movement can be prevented by checking to see that there is sufficient air pressure and that the air bag is not restricted. Worn bed rails will also allow movement. If you are unable to resolve this problem, the machine manufacturer should be contacted.

CLOSED

If the feed dogs are not square, or if they are damaged or loose, the wood may be fed at an angle. This will also result in the incorrect joint shown.

FINGER ENDS VARY IN THICKNESS THICKER

There could be several reasons why you may experience this problem. The wood may be moving during the cutting process as outlined in the previous section. Also, your machine may not be feeding the material squarely, or it may be unable to hold the wood securely due to other factors. If you suspect that the machine is to blame, you may need to contact the manufacturer.

If your cutters are extremely dull, there will be excessive tool pressure that may contribute to movement of the wood. Please refer to the section on grinding (page 84) and be certain that the cutters have been sharpened enough to remove all of the dullness. It is possible to grind the cutters only to find that they are still dull if enough material is not removed to bring the face of the cutters to sharp edges and corners. THIN

JOINT OPEN AT TOP OR BOTTOM CLOSED

OPEN

The trim saw adjustment is extremely important, and your finger joint machine manual will offer a complete guide on alignment of the saw. However, the problem shown here could be a direct result of the misalignment of the trim saw. Another reason for this problem may be that the material handling system on your machine may be allowing the wood to miss all or part of the trimming operation. It is extremely important that the wood be held securely and squared perfectly before the wood comes to the finger joint head itself. Remember that the finger joint cutters do not contact the ends of the fingers. The critical ends of the fingers are cut by the saw, and if the saw is out of alignment, it will be difficult or impossible to achieve a good joint.

FINGER JOINT TROUBLE-SHOOTING

FINGER JOINT TROUBLE-SHOOTING PROBLEM #1 - Pressed board has bend to thin side - HORIZONTAL JOINTING

Possible Cause Cure

Board end is not perpendicular, so trim saw won’t “cleanup” the end. If the trim saw doesn’t cut perpendicular, then the boards will develop a bend when pressed together. This problem worsens when too much pressure is used in the press assembly. Adjust chop saws to cut perpendicular.

Possible Cause Cures

Boards have moved during cut so board ends are not being trimmed perpendicular. 1. Too much tool pressure during cut. Reduce cutting pressure by either: sharpening tooling, slowing feed rate, increasing RPMs, or increasing number of cutting teeth. 2. Check air bag for leaks or twists which would affect hold down pressure. 3. Board height varies too much and shorter boards do not get adequate hold down pressure. Sort boards closer to the same height dimensions. 4. Replace worn bedrail inserts, which may be allowing board movement.

Possible Cause Cure

Lugs are misaligned and not square to bedrails. Square lugs to bedrails. Square lugs in front of drive motor. May need to check the drive and tail sprockets.

Possible Cause

Centerline of board is beyond the centerline of the anvil and ram of the press. More pressure is asserted on one side of the board than the other. Adjust anvil and ram closer to centerline of board width. Always have anvil and ram slightly to the outside of centerline of the board to avoid accidents if board comes apart in press.

Cure Possible Cause Cure

Press assembly has indexing fence on the opposite side of the lug side of board. Boards have been profiled and trimmed while indexing on the lug side. The indexing fence in the press should always be on the lug side of the board. Move press assembly to opposite side of scarfer unit.

PROBLEM #2 - Pressed board has bend to wide side - HORIZONTAL JOINTING Possible Cause Cure

Trim saws have too much lead, thus, cutting a concave board end. Adjust lead of saw blade to no more than 0,1 mm.

Possible Cause Cure

Long board sections have too much bow. May have to cut the longer board sections and finger joint again.

Possible Cause Cure

Trim saws are tilted from top or bottom causing an unsquare board end to be cut. Square saw blades from top to bottom with bedrails (flying cut-off saw may also need adjustment).

STARK

FINGER JOINT TROUBLE-SHOOTING

FINGER JOINT TROUBLE-SHOOTING - Continued

PROBLEM #3 - Pressed board falls apart Possible Cause Cure

Too little pressure used in press assembly. Use load meter to adjust assembly pressure to 28 - 35 kg/ per square cm. for the cross section of the end of the board. Less pressure than this will leave too much of a glue line and won’t allow glue into the wood fiber. Adequate pressure is also needed to ensure contact on the sides of the fingers. More pressure will be needed for joints longer than 5/8”.

Possible Cause Cure

Glue penetration into wood is not adequate. Moisture content of wood is too high (i.e. above 15%). Dry and reduce moisture content.

Possible Cause

Temperature is too cold to allow glue to coagulate and form a reliable bond. Chalking of glue is evidence of this condition. Keep boards and surrounding work area above freezing temperatures.

Cure

PROBLEM #4 - Pressed board has misaligned joints (joints jumped a tooth) Possible Cause Cure

Shoulder of finger joint is too thin and is being forced in between fingers. Always set the thickness of the shoulder of the finger joint to be larger than the tip thickness of the thin finger joint cutter.

Possible Cause Cure

Infeed roller bearings are worn out. Replace roller bearings.

Possible Cause Cure

Too much thickness variation in the boards. Sort boards for closer height dimensions.

Possible Cause Cure

Boards are being crowded together before being held down by infeed rollers. Adjust feeder assembly, so boards are under the infeed rollers before crowding begins.

Possible Cause Cure

Crowder roller feed table is not flat, which allows boards to bounce and misalign before final crowding. Replace or resurface infeed support table.

PROBLEM #5 - Pressed board separates at joints after the moulding operation Cause Too much pressure is being used in the press assembly. Once the moulder cuts into the board, it relieves over-stressed fibers, and the fibers separate from the glue line. Cure Check the total force being applied to the boards in the assembly press by using a load meter. The load meter reading should be between 28,57 to 35,15 kg. per square centimeter for the cross section of the end of the board. For example, a 2x4 has 8 square centimeters of cross section and would require 225 to 281kg per s square cent. of force. Pressure will vary somewhat with finger joint length. To calculate the total force of the press: 1. Determine the diameter of the cylinder of the press and the Pounds per Square Inch (P.S.I.) of the hydraulic line leading into the cylinder. Put these figures into the formula: (3.1416 x D² ÷ 4) x (P.S.I. of hydraulic line to cylinder) = Z where D = Diameter of hydraulic cylinder 2. The answer, Z, is then divided by the square centimeters of the cross section of the board. This will yield the force in pounds per square inch of the board cross section and should range between the 28,57 to 35,15 kg. per square centimeter as stated above. Note: This force is at the front of the pressure cylinder. As this force travels down the board, some will be lost due to the length of the board, number of joints, board height/width, and joint length.


STARK

FINGER JOINT TROUBLE-SHOOTING

FINGER JOINT TROUBLE-SHOOTING - Continued PROBLEM #6 - Some joints in board are not pressed together (may occur at end furthest from press cylinder) Cause

Insufficient force used to close joints due to: length of board, joint length, wood species, or board height/width. As these factors absorb more of the total force, less and less pressure is applied at the end of the board. For example, as board width increases, more force is required to close the joints furthest from the press.

Cure

Calculate needed force required and adjust P.S.I. to hydraulic cylinder. Always check with the machine manufacturer to verify the maximum allowable pressure for your machine. Never exceed this recommended pressure. Note: A load meter can identify the total force. When using a load meter, always place it at the board end away from the hydraulic cylinder to record the lowest pressure. Always place a piece of metal on each side of the load meter donut to prevent it from being crushed into the wood and to ensure a more accurate reading of the force.

PROBLEM #7 - Joint open on one side (board has varying tip thickness from one side to the other) Possible Cause Cure

Excessive tool pressure, which causes board movement while cutting. Calculate Chip Load, Cutting Speed, and MRR, as shown on previous pages , and verify that all are within acceptable range. If not, make the appropriate changes to reduce tool pressure.

Possible Cause Cure

Board is moving during cutting process because of worn bed rails, low air bag pressure, or a twisted air bag. As a result, board end is not square to machine spindle. Contact machine manufacturer for replacement or rebuild parts.

Possible Cause Cure

Board end is too unsquare to trim. Sort boards to eliminate scrap.


STARK

FINGER JOINT TROUBLE-SHOOTING - TEAR OUT

Tear-out is defined as excessive splintering and chipping of the wood surface that the tooling is exiting.

Conditions That Cause Tear-out: Dull Cutters: Sometimes tear-out can be eliminated by simply resharpening your cutters more often and verifying that your grinding procedures are correct. Too High of Feed Rate: Tear-out can occur if your feed rate is too high. To see if this is a problem, you need to calculate the number of knife “Marks per mm.”

Grain Orientation: Direction of wood grain can reduce or accentuate tear-out (see graphic below). Bad Lugs: Lack of proper backing support can cause tear-out. Lugs will not function properly if they are excessively worn or rounded on the supporting edge. The brush system in front of the hold-downs should not run on the lugs themselves, or it will cause excessive wear and rounding of the supporting corner on the lug face. Lugs that are out of adjustment can also contribute to tear-out. The finger joint cutters should just touch the lug. Species of Wood: The type of lumber and grain structure can further add to tear-out. Materials that splinter and clog the finger joint head quickly (e.g. Hemlock Fir) will produce excessive tear-out. Cutting Angle: Proper cutting angle is critical in producing a good joint. If cutters are sharpened without using a proper hook gauge, tear-out can occur. Using a blunt cutting angle (under 18°) can cause tear-out due to excessive tool pressure. Also, using an improper or damaged set-up stand to set-up your heads can cause tear-out. Double-check your set-up and sharpening procedures to be sure this is not a problem. Moisture Content: Dry lumber will promote tear-out. We recommend moisture content to be between 8% and 15%. Excess Radial Run-out: Tendency of the head and cutters to fluctuate up and down as they rotate is known as radial run-out. This is caused by component inaccuracy, tolerance buildup, worn spindles, or imprecise systems used to attach the head to the spindle. Joint Length: The amount of tear-out decreases directly as the tip and shoulder sizes decrease. Switching to a shorter joint can greatly reduce tear-out. Saws: Chop and trim saws often cause tear-out . It is important that the proper saws are used and that sharpness is maintained. This will prevent tear-out on the exit side of the board which is caused by excessive saw tooth pressure.

This grain orientation will cause tear-out.

This grain orientation will reduce tear-out.

Cause Cure

Board is being trimmed unevenly. Review finger joint machine operation manual for trim saw adjustment. Check the transfer belt to determine if belt is moving too fast and pushing the board away from the lug before it enters the air bag section. This will cause the trim saw to miss the board end.

Cutter stack moved during setup and rotated too far forward for the correct set-up angle. Reset the head on a set-up stand and check alignment of cutter stack to alignment post. Check set-up stand for damage or excessive wear.

PROBLEM #12 - Joint Fingers Have Convex Gap on Side Possible Cause Cure

Cutters were not resharpened according to hook gauge. Cutters have too blunt of a hook angle. Grind the cutters to match the hook angle

FINGER JOINT TROUBLE-SHOOTING - TRIM SAWS

Trim Saws perform precision squaring of the board end and precision trimming of finger joint depth. Trim saw blades should have directional left or right-hand teeth (9 and 1 pattern suggested) with the finish side toward the board. Like Saw Blade 0,1 mm. Max.* chop saws, dull and improper trim saws Minimize the amount to be cut by the trim saw - not to exceed 3 mm. will cause fiber separation. The kerf Saw Blade *Exaggerated for clarity of the trim saw should always be less than the saw blade thickness, while not exceeding the thickness that is required to clean up and square the boards. In other words, there should never be a board end slice left over after trimming. How much wood is being trimmed off the board? To find out, let the board go through the trim saw, pull it out and then send it through the same saw again. The distance between the scribed bed rail marks is the amount being trimmed off by the saw. For proper squaring, the trim saw needs to be perpendicular, both vertically and horizontally, to the board with a lead of no more than 0,1 mm. A bit of lead is desirable, or the saw will double-cut the board, causing bowed stock at the assembly press. Conversely, too much lead will produce open-concave board ends, which will also bow when pressed in the assembly. If the trim saw motor bracket doesn’t have its own mechanism for adjusting lead, then simply shim under the bracket itself to obtain the correct lead. Rotation of the trim saw blade can reduce tear-out. The blade should enter the board surfaces where tear-out is least desired and exit the board where quality is least impacted. The following figures show tear-out minimized on “reverse” type joints by configuring rotation and saw exit in areas that are removed with the thick finger joint cutter. By design, the tear-out is cleaned-up by the thick finger joint cutter. Saw tips should exit no more than 3 mm. through board in order to keep more teeth in the cut, reducing tool pressure and tear-out from the saw.

FINGER JOINT TROUBLE-SHOOTING - RIP-OUT

Rip-out is defined as the removal of fingers in the center of the profiled board and the jamming or embedding of this material between stacked cutters. In turn, this clogged material produces more rip-out by prohibiting the clean cutting of adjacent fingers.

Conditions That Cause “Rip-out� Species of wood: Materials that splinter and clog up finger joint heads quickly (i.e. Hemlock fir) will experience rip-out, because the wood has erratic grain structure with different degrees of strength. Moisture content: Extremely dry lumber will promote rip-out. We recommend that finger jointed lumber remain above 8% moisture content. Cutter tip thickness: Tips thinner than 0,76 mm. tend to cause rip-out. One cure for this problem is to setup your finger joint cutters in a staggered profile. The quickest way to try this cure is to rollback every other cutter out of the cutting circle, so they will do no cutting. On the next stack of cutters behind the first ones, roll back the opposite cutters from the first stack. In effect, this will make a 10-bolt head cut like a 5-bolt head. Keep in mind, you will need to slow your feed rate by 50%, because you have 50% of the normal amount of cutters. Another potential cure for this situation is to mount a brass head cleaner on the machine shaper.

Multiple Set-up Options: l

Staggered

Gullet Radius: An improperly maintained of profile can prevent wood chips from flowing clear of the stack of cutters. Compacted fiber builds up until the tips of the wood joint are ripped out because of a lack of clearance. A properly formed of profile acts as a chip breaker.

MEASURING JOINT LENGTH

Incorrect Method

Periodically, joint length measurements must be taken from the finger-jointed boards produced. Joint length measurements are used for: Machine setup - Trim saws: Each end must have the same length to prevent end gaps as the boards are pressed together. True Joint Length: Resharpened tooling will produce a shorter finger than the nominal design length. This is caused by burrs on the cutter face which are removed during the first few hours of production.

Long locating surface of caliper. Inaccurate method because jaw is aligned by sight. Non-perpendicular Keep caliper perpendicular to shoulder for correct length.

Dull Tooling: As the tooling dulls, joint length increases. When a determined length is reached, the tooling needs to be resharpened. The graphic illustrates correct and incorrect methods for measuring the length of a finger joint. Please note that the correct method uses longer surfaces of the digital caliper for location. By locating on these long surfaces, joint lengths have better repeatability, to within 0,07 mm.

Correct Method

Caliper tip may not fit into valley of finger joint.

Do not measure along finger slope. Long locating surface of caliper.


STARK

SPINDLE PERPENDICULARITY AND CROSSLINING

STARK would like to state that we are tooling manufacturers and not machine manufacturers; however, the best tooling in the world won’t perform correctly unless the finger joint machine is also perfectly tuned. Therefore, one of the most important aspects of the machine is the spindle and its perpendicularity to the bed rail grooves. As shown below, a non-perpendicular shaft will not be found by simply indicating on the spindle itself. If the shaft is running true, then the indicator will show little or no run-out, even though the spindle may be tilted in relation to the bed rail grooves.

Spindle

If a spindle is not perpendicular to the bed rail grooves, the finger joint head will “plow” through the wood and produce a joint that needs to be shortened in order to fit together. The finger joint cutters will also be galled on the sides, because there will be little or no side clearance between the wood and the cutters. Crosslining is a procedure to check the perpendicularity of the spindle to the bed rail grooves. This procedure utilizes a dial indicator with a magnetic base attached to the spindle and then swung across the bed rail grooves at four different positions. Measurements are taken at all four positions and verified to within 0,076 mm.” of each other. Do not take measurements on the bed rails themselves, as they may be worn. Remove the bed rail inserts and any spacers that may be under the inserts that were used to level them. Clean out the bed rail grooves and insert a 25 x 25 x 12 metal block into the grooves. Swing the indicator to each of the four locations shown below and let the dial indicator “read” off the block at each point. The variance between the four measurements should not exceed 0.076 mm, as stated above. This variance may need to be smaller for short joints (i.e. , 4mm, 5mm joints), as they require more accurate spindle perpendicularity. Adjustments should be made at the spindle motor mounting bracket on the machine.

TILTED HEAD SYNDROME

Wide inside tips

Tilted Head Syndrome is a problem where, even though the spindle is perpendicular to the bed rail grooves, the head is not perpendicular to the spindle, as shown in Figure 1. This problem usually results from the head not properly locating on the spindle due to nicks or burrs on the collets (centering cones) or the collet faces of the head itself. Tilted Head Syndrome can be detected by placing a mag-base dial indicator securely to the machine so that the indicator tip can ride on the top of the cutter stacks at the tip of the cutters. With the spindle motor locked out, rotate the spindle one revolution and read the variance between the cutter stacks.

All cutters are on the same cutting plane

If the variance between the tops of the stacks of cutters is more than 0.076 mm.then the head is likely tilted, as shown in Figure 1.

The high and low readings on the cutter stacks are usually opposite of each other, but Outside and inside tips are equal the readings will not necessarily remain on the same cutter stacks for collet-type heads. Figure 2 If the spindle nut is loosened and the head is rotated 180°, the high and low readings will move to different stacks. This tilted condition makes the cutters act like they have wider pitch than they actually do, which, in turn, produces joints with thinner tips that need to be shortened to make the joint fit together. However, when the joint is shortened, the tip of the wood finger becomes thicker, producing more of a butt joint within the finger joint. The result is a finger joint with reduced strength. The finger joint head will also have only a few opposite stacks cutting while the rest of the stacks are missing the wood. This increases the chip load for the cutters that are doing the work and decreases the time between sharpenings. It is possible for a 10-bolt collet head to cut like a 4-bolt head, because all the cutters are not precisely following the same plane. Additional tear-out on the back of the boards will result because of the increased tool pressure. The STARK Loc hydraulically-centered finger joint head was designed to eliminate this misalignment. Hydraulically-centered finger joint heads “grab” the entire surface area of the spindle, thus increasing the perpendicularity of the finger joint head to the spindle as shown in Figure 2. Joint lengths are maintained better, because all the cutter stacks cut evenly, reducing the chip load on each individual stack. Additional benefits include reduced tear-out and extended cutter life.

WORN LUGS Worn lugs allow boards to move as they are being cut by the finger joint head and will produce a joint much like that of the “Tilted Head Syndrome.” See the illustration to the left. Never allow alignment brushes to ride over the lugs and make contact. This will eventually wear the lugs down. If the mating surface of the lug is worn so that less than half of the height of the back of the board is supported, then the board will move during the cutting process. Examining the bottom of the board can identify this. Bed rail scribe marks that are deeper on the front of the board and less on the lug side of the board indicate that this problem is happening.

TOOLING BALANCE

Balance of the finger joint head is extremely critical to a good finger joint. Even a very slight amount of imbalance or improper setup may produce a joint that will fail. All cutter stacks should be assembled so that they will keep the head in dynamic balance during operation. The best way to ensure cutterhead balance is to weigh each stack of cutters, and then install stacks that weigh the same in a configuration 180 degrees across from each other in the head. If there is more than one tenth of a gram difference between stacks that will be installed across from each other, the heavier stack should be lightened by grinding material off the flat area on the back of the cutter.

HEAD BALANCE All STARK cutterheads are factory balanced to extremely tight dynamic balance specifications before they are shipped. This balance is critical to a precision finger joint. It is counterproductive to install perfectly balanced cutter stacks in a head that is of questionable balance. If the cutter stacks and the head are not both balanced properly, it will be difficult to obtain a good finger joint. Poor balancing practices will contribute to vibration, runout, and a poor joint. If there is any reason to suspect that your head is out of balance, or if it has been dropped, or if it has hit any foreign object, please contact the plant for authorization to return it for possible rebalancing.



TG25 MODULAR BLOCK ADVANTAGES A very important economic advantage of our tools is the possibility to replace the knife!! This thing is very important for 2 reasons: - is some finger tooth is break is possible to replace only this knife, while in brazed block il will be necessary replace the cutter - when the tooth is finish, in brazed cutter you need to replace all the set, while with our tools you need to replaced only knives!!!

TG25 modular block is suitable for vertical and horizontal jointing. All the inserts are in HW and you can use it for soft, hard or exotic wood with high performances!!With soft woods you can work without resharpening about 11.000 meters. An important advantage is: - low noise and low AC power request!! - every insert can be resharp 3.5 mm ( about 19 times !! ) - you can resharp the insert or directly into the body or with device ZAF 30 All the biggest or partners suggest this system because is very strong and very easy for maintance. In order to grant an excellent final result, we increase our standard items with a new one with more teeth. Now also big plants, especialli Weinig Combipact, Turbo S, HS 120 with a high number of cycles ( more than 5 cycles per minute ) can be equipped with our TG25 with Z=4+4+4 or Z=5+5+5. All the others machine with less than 4 cycles can be equipped wit our standard TG25 with Z=3+3+3
