The company was aware that traditional tools could not provide the required accuracy standards set for liner manufacturing – the liner is the heart of the screw pump – and manual operations would affect the quality and impact business. It was time for technological advancement, for having the right tools and processes in place to manufacture the liner. Champaneria approached Seco Tools India for assistance. “The demand from our end was to achieve accuracy and consistency, and to eliminate operator dependency,” he says. “This could be ensured by using the right boring bars to produce our pumps.” Vidyadhar Kulkarni, Regional Application Expert, Automotive, Seco Tools, lists the obstacles the Seco team faced in achieving the required quality specifications: “We needed to provide long tools with a length-to-diameter ratio above 7. Second, all holes have to be machined in half bore condition, causing very high interruption. Third, we needed to control the ‘h7’ tolerance for centre distance between the Seco’s Jignesh Prajapati takes axes of all three bores, along with the individual a closer look at the end result after three steps of machining. qualities such as cylindricity, concentricity, parallelism and surface roughness.”

Seco steps in In screw pump applications, the diameter-length ratio has to be exceptionally long, the centre distance must be precise and the surface finish must be excellent. To upgrade Tushaco from using traditional boring bars, Seco provided a total machining solution with a defined process – from roughing and semifinishing to final finishing. This solution was implemented for the entire range of Tushaco pump liners.

The machining of the component liner was complex, and the Seco team spent time on Tushaco’s production floor to study and understand the technical requirements. The end result was a solution for the complete process, from roughing to finishing of bores. “This included plunge milling solutions for rough and semi-finish of bores and the Seco patented dampening tool – Steadyline – for finishing,” says Seco’s Jignesh Prajapati, Assistant Manager, Sales. But Tushaco’s concern was reinvestment in capital tooling. “In a low-cost country like India, we do a cost-benefit analysis to keep our final product cost competitive,” says Champaneria. “This cost could be offset with benefits such

The end result is marked improvement in the quality of applications and solutions Tushaco gives its customers. Tushaco grew by 25 percent in 2012. “We got a breakthrough recently when the parent company certified us for twin screw exports, directly to our customers in Europe,” says Champaneria, who also expects other markets such as China, Malaysia and Thailand to become possibilities in the near future.

TRENDS IN JET ENGINE MANUFACTURING HOWARD WEAVER, Rotating Parts and Structures Lean Lab Leader, and KEVIN MEYER, Lead Engineer/ Technologist in Cutting Tools, at General Electric Aviation share their thoughts on general material trends in the jet engine market.

1. Fuel economy Global airlines must develop a strategy for long-term profitability, and fuel costs may constitute up to half of their operating costs. Much of the industry’s focus is on thermodynamic or materials technology that reduces engine weight or improves fuel efficiency. Software-based products can also achieve fuel savings, helping airlines lower operating costs by suggesting the most efficient speed and flight course, burning fewer gallons of fuel.

4. Ease of repair Grounded planes hurt airlines in terms of profitability and operations, so ease of repair is a major consideration. GE uses the customer’s desired repair delivery date as its standard; in 2012, we were 97 percent on time. To solve spare parts availability, we anticipate which customers will have shop visits in the next year, and what parts we should order to be ready. Of course, we also want to minimise inventory costs, so the demand forecast must be accurate. We have a whole business channel focused on component repair, which is lower in cost than using new material. We get 'serviceable material’ from retiring engines, refurbishing the parts. For an engine on its last shop visit before it retires, having lower-cost options can mean serious savings.

2. Weight savings Another way to reduce weight is by developing strong and durable materials that are lighter. The best examples are ceramic matrix composites (CMCs), which have one third the density of the metal alloys they have been replacing in engines. In addition to fuel burn benefits, CMCs offer an increased temperature margin that can handle thrust increases.

3. Titanium aluminides As an intermetallic compound, titanium aluminide (gamma titanium alloy) features strong interatomic ties that make it resemble ceramics. Its relative brittleness can be countered by the addition of elements such as niobium and chromium. Able to withstand heat up to 800 degrees Celsius, it has half the density of more typical nickel alloys.

8 edge [2·2013]

5. Additive manufacturing Today "additive manufacturing” (also known as “3D printing”) has a limited build envelope, a limited number of alloys and a limited amount of speed and efficiency to build parts. However, GE expects to see more alloys produced more efficiently by additive manufacturing. With this technology, GE can engage in designs that are impossible to create using traditional machining methods. Additive manufacturing reduces the number of parts by replacing assemblies with single parts, and it will lead to new designs that save weight and increase fuel efficiency. By reducing the number of manufacturing steps, additive manufacturing will also lower the cost of parts.

Seco’s PCA system allows for a detailed analysis of cost savings.

SUBCONTRACTOR YUKSEL TURN TECH provides turned components, such as cable and hose connectors, to many industries, mostly communications, automotive and HVAC. The company’s 4,500-square-metre factory halls are located in an industrial area in the village of Kvistgård, Denmark. They contain highly automated machinery, six robots – one is the largest in Denmark – and 27 CNC machines that produce millions and millions of small parts each year out of about 2,000 tonnes of brass. For more than 10 years Yuksel has provided one of its largest customers, Danfoss Semco, with three types of brass water sprinkler nozzles and a stainless steel nozzle that was sourced externally. Danfoss Semco, originally formed to focus on the marine and offshore industries, now sees great potential onshore for fire-fighting equipment. But certain environments, such as slaughterhouses, are too tough on brass nozzles due to the amount of ammonia in the air.

D E-LUG E NOZ Z LE CNC MACHINE: Okuma MacTurn 250-W TOOL PACKAGE: It contains 13 different tools including drills, Jetstream Tooling®, threading, milling and multi-directional turning. Up to 52 different tools can be used in the machine.

Yuksel Turn Tech’s Production Manager Kenth Wrist-Jensen always goes for the best quality and prioritises productivity.

In 2012 Yuksel won a three-year contract with Danfoss Semco to produce two nozzles in brass and one in stainless steel, but on the condition that they invest in new equipment. They needed to produce the stainless steel model themselves in order to match growing demand. Yuksel’s Production Manager Kenth WristJensen asked around for the best equipment and tools. “We always go for the best quality whether it concerns brass, steel, tools or machinery,” he says. “If a tool costs 90 euros and gives us a production capacity of two million parts a year, it is so much better than buying a tool for 70 euros but ending up with a yearly production of 1.2 million parts.” Seco’s name came up as a recommendation when it comes to tools for processing stainless steel components. “We made a complete MRTCET (Machine Related Tooling, Component Engineered Tooling) project with time calculation and tool package,” says Michael Mellerup, technical consultant at Seco Tools Denmark. The analysis showed great potential in purchasing a machine with tools to make the stainless steel nozzles in-house. In December 2012, the Okuma MacTurn 250-W arrived and a few weeks later the CNC machine was up and running.

Yuksel Turn Tech Founded in 1969 by Turkish engineer Yüksel Caglar. Owned by Morten Bengtsson since 2001. Yuksel Turn Tech employs 30 people with a turnover of 40 million Danish kronor. It is a sub-supplier specialised in production and assembly of metal components in large and small series.

The company supplies the automotive, telecommunications, electronics, HVAC and fire-fighting industries with automatic turned parts, primarily brass, but also stainless steel. Yuksel makes 18 million parts for the telecommunication industry every year.

“Our experience lies in long production series where we can produce a new part every third second,” Wrist-Jensen says. “This is a different ball game. In this machine we make one part in three minutes.” Seco helps Yuksel to optimise production by constantly making analyses with the new, enhanced version of the Productivity and Cost Analysis (PCA) system. After the first few weeks, the calculations showed that cost-savings would amount to 1.25 million Danish kronor per year. Wrist-Jensen says the system helps to answer a number of questions: “Where are the bottle necks? How many parts can we do in 24 hours? How can we improve quality even further?” One example is the use of cutting oil. “We have cut costs per part by 50 percent by using 100 percent cutting oil instead of the traditional oil-water emulsions,” says Wrist-Jensen. Another example is an improvement in how the brass and steel tubes are moved from the warehouse to the shop floor. “We use a hydraulic crane equipped with soft slings instead of lifting them with a forklift, which might cause scratches on the metal,” Wrist-Jensen says. Before the crisis in 2008, Yuksel had 60 percent of its business in the automotive industry. That changed overnight; in search of new business opportunities, the company has made investments over the last three years in changing its production capacities. Wrist-Jensen says, “In the future we will make smaller series and many more stainless steel components.”

Angle of attack Patrick de Vos, Corporate Technical Education Manager at Seco Tools Group, explains how different cutting geometries influence the machining process. WHAT DO WE MEAN when we

talk about a good cutting geometry? A cutting geometry is a range of cutting-tool geometrical properties that influence tool life, chip formation and evacuation, stability and safety. Essentially, a good cutting geometry is an arrangement under which chips are correctly formed without much effort. The properties of a cutting edge are determined, firstly, by the carbide grade used and secondly by the edge’s geometry. Both need to be correctly selected in relation to the type of operation at hand. A practical way of evaluating a cutting geometry is to examine chip formation during cutting. Ideally, chips should both be neither too long, nor too short, and be spiral-shaped. T-land geometry

Chip breaking geometry Cutting edge geometry

A good cutting process involves efficiently forming and evacuating chips. This is determined by the basic geometry of the cutting tool – how the cutting edge is positioned in the tool holder or milling cutter. A positive geometry (when combined with a flat rake face) reduces cutting forces and heat generation. Unfortunately, the chips are longer and the mechanical strength of the cutting edge is lowered. A negative geometry provides good edge strength and creates shorter chips, but increases cutting forces and heat. However, the true cutting geometry is found on the edge itself. This cutting geometry consists of three parts: the cutting edge geometry (edge treatment or edge preparation); the T-land geometry; and the chip breaking geometry (rake face geometry). There are three basic types of cutting edge geometries: sharp, rounded and chamfered. A sharp cutting edge gives low cutting forces, reduces built-up edge tendency, gives longer tool life but is less stable. The T-land geometry is the transition zone between cutting edge geometry and chip breaking

geometry. Positive T-land geometries give lower cutting temperatures, less wear, increased cutting speed capacity, smaller maximum pressure zones and lower cutting forces. But, there is higher tension-stress concentration and an increased risk of chipping of the cutting edge. The cutting edge geometry and T-land geometry combine to determine the tool life of the cutting edge. To take full advantage of cutting edge and T-land geometries, the feed rate needs to be greater than the size of these geometries. The true chip formation process is determined by the chip breaking geometry. A hard-breaking geometry takes the chips the moment they are formed, deforms them and breaks them, resulting in short, broken chips. The disadvantage is a fragile cutting edge due to the concentration of forces. With a soft-breaking geometry chips are longer before they break. This geometry gives on the other hand a stronger cutting edge. Medium geometries lie somewhere in between. Patrick de Vos, patrick.de.vos@secotools.com

INDU ST RY POWER GENERATION

Siemens in short The Siemens gas turbine plant in Berlin, Germany, supplies highly efficient, environmentally friendly turbines for power plants. The newest addition to the product range, the SGT5-8000H, is setting the global standard in terms of environmental protection: While the turbine has a record-breaking power output of 375 megawatts, when in combined cycle with a steam turbine, its process efficiency can be increased to over 60 percent. Compared to the most common turbines in use today, this equates to savings of about 43,000 metric tons of CO2 emissions each year. Despite their enormous size and weight, gas turbines need to be assembled with extreme precision, using highly advanced techniques. For example, the rotor itself is a multi-component element that can easily weigh 100 metric tons. In operation, it rotates at 50 revolutions per second – with the tips of the blades only a few millimetres away from the casing. When it comes to assembly, fractions of a millimetre decide whether the turbine will run optimally when it is later installed in the power plant. A single gas turbine includes approximately 2,400 blades, and each blade is subjected to extreme stress during operation. The temperatures inside the turbine during combustion, for instance, are in some cases as high as 1,500°C. The blades can bear these challenging conditions thanks to an innovative production technique that makes perfect air-cooling possible. Andreas Gross joined Siemens in 1978 and is currently team leader for the production of smaller components, including the CNC milling of bearing brackets. Seco Tools has been supplying the company for decades, and Seco’s technical manager Steffen Köckeritz and salesman Bernd Scheunemann work closely with Gross and his colleagues, providing support whenever it’s needed. “If we have a milling problem, I need only to call Mr Scheunemann,” explains Gross. “If he’s not already at the plant anyway, he quickly pops by. They’ve always managed to find a solution.” The implementation of the new milling cutters is the latest example of a development resulting directly from the cooperation between the two companies. Scheunemann, who’s been advising Siemens

The Siemens gas turbine plant in Berlin has 3,500 employees representing 46 nationalities. The first gas turbine for a power plant was delivered in 1972, and since then more than 800 have been built for customers in more than 60 countries. These are destined for the 50- and 60-Hz market and generate between 113 and 375 MW. Alongside manufacturing, the site carries out test-runs of turbines and turbine components in-house, and also provides 24/7 service for installed machines.

for the past 20 years, saw the potential for optimising the bracket milling process by using Seco’s HighFeed2 cutters. Instead of cutting with greater depth, these cutters combine shallow depth of cut with high feed per tooth, leading to a higher metal removal rate than normal. Moreover, the cutting forces are directed at the machine spindle in the axial direction, reducing vibrations and thus extending tool life. This method achieves the high degree of precision demanded by Siemens. Since its introduction at the Siemens plant in early 2012, the HighFeed2 has led to time savings of up to 90 percent. This allows Siemens to produce more

components per CNC machine for a better return on investment. “Naturally, I was expecting to see a saving,” says Gross. “But I really didn’t expect it to be as considerable as this.” For the milling of gas turbine pockets, the new high feed technique has reduced machining times from 90 minutes to less than 10. Since there may be as many as eight of these pockets for each turbine, this represents substantial savings in terms of overall production times. Gross is confident that the collaboration between Siemens and Seco will lead to further optimisation in future, as well.

High-feed milling achieves up to three times faster machining than conventional methods. Instead of cutting more deeply, the process combines a maximum cutting depth of 2 millimetres with a much greater feed rate, allowing for a higher metal removal rate than normal – up to 1,000 cubic centimetres per minute. The method takes advantage of small setting angles, producing minimal radial and maximal axial cutting forces, which in turn reduces the risk of vibrations and stabilises machining. And although it’s a roughing method, the small depths of cut generate a shape close to the final desired form, eliminating the need for semi-finishing.

WHEN THE UK SUBSIDIARY of

Seco moved to a more modern building in 2012, it made sure the new premises had solid green credentials. Waterless urinals, centralised cooling systems and a state-ofthe-art air conditioning system were all installed in the new facility in Alcester in Warwickshire, England. But the most ambitious feature was a large solar array on the roof of the building, with the potential to reduce the production of greenhouse gases and lower power bills. Philip Madkins, Seco UK’s Safety and Environmental Manager, says the company first investigated electricity-generating solar panels some years ago, but was not impressed by their efficiency. “We looked into solar eight years ago at the old site, and the panels weren’t that efficient,’’ he says. “But today’s panels are far superior. You only need one panel

today to do the job of 10 or 15 panels 10 years ago.” After undertaking research on different options, the company commissioned UK firm Sanctus Energy to carry out the installation of the chosen system, which features 200 Sanyo solar panels, with a maximum energy output of 50 kilowatts. Despite the oftencloudy conditions in Alcester, the system produces power every day. “Even when it’s dull we’re producing 12 to 20 kilowatt hours (kWh) a day,” Madkins says. “On a sunny day that might go up to 80.” He says the system, which began operation in July 2012, had produced 17, 800 kWh of power by the end of the year. It is expected to reduce CO2 emissions by 21 tonnes a year, bringing significant costs savings for Seco. “It’s a win-win situation,” Madkins says. He says the installation was funded with the assistance of

Seco’s Green Fund, at a cost of 117,000 British pounds. The UK subsidiary receives a green energy incentive payment from the UK government for every kilowatt of power the new system generates. The company’s power bill has also dropped, and at quiet times, such as weekends, the output of the solar array exceeds Seco UK’s electricity requirements. The company is then able to earn money by exporting power to the grid. Madkins says the system should pay for itself in eight to 12 years, depending on how efficient the solar panels prove to be. At the end of 25 years, the company should be better off to the tune of 381,000 pounds. “It’s looking really promising,” he says. “We’ve had no problems with the panels or the inverters. It’s all just working away.” Madkins suggests other companies, even those in cloudy areas, look into solar panels. edge [2·2013]

THE MOST DIFFICULT aspect of the competition, says Melas, was timing: “We had set amounts of time for programming the Mastercam and for machining. Even though we finished the programming early, we couldn’t start on the machine until that time was up.” But Melas was pretty confident of his capabilities, and he won bronze in the individual competition for CNC Machining. “But coming first in the team challenge was really unexpected,” Melas says. Afterwards, Melas found he was in demand and was headhunted by a Belgian milling company. He has since been offered a better-paid job as a milling machine operator in Luxembourg. Alain Stas, Director at TECHNOFUTUR Industrie, says, “The Euroskills competition is a fantastic opportunity for people like Mathieu to gain experience, improve their skills, and hopefully get a job as a result. Our ultimate aim is to see our students find work, and Euroskills can act as a springboard into the industry.” Stas was also approached by Euroskills to be Workshop Supervisor for the Milling competitions, setting up partnerships with tool suppliers Seco and Mitutoyo, machine manufacturers Buhlmann and Huron and CAM software from Meca-consult and Mastercam. “These partnerships were very positive for TECHNOFUTUR Industrie, enabling us to develop a much closer working relationship with key suppliers in the industry,” he says. Euroskills drew 50,000 visitors during the threeday 2012 edition in Belgium. “It’s a great way of stimulating young people to get involved in the industry,” says Stas. “The numbers of new entrants are declining, and Euroskills can only help raise the profile of the milling industry and inspire young people to think about getting involved. I’m very proud of our students and how well they’ve done.” “Competitions like Euroskills are great, but for me, the best part was the preparation, when I got to meet the other candidates and the whole team,” says Melas. “In fact, I’m entering Worldskills later on this year in Germany – winning Euroskills has really given me a taste for competition!” edge [2·2013]

Accurate analysis Park Man-gyo, Seco’s manager for technical support in South Korea, says successful cures to customers’ problems depend on proper diagnoses.

“I BELIEVE THE IDEAL relation-

ship between a customer and a supplier is that both parties should respect each other,” says Seco’s Park Man-gyo. “This leads to a win-win situation for both sides.” Park is responsible for Seco’s technical support in the country, which means he must solve a wide range of issues. “When I am faced with challenges, I thoroughly analyse the problem and figure out the cause of it,” he says. “Then I try to fix it or improve it by discussing it with colleagues. Afterwards, the findings are shared with everyone to prevent the problem from re-occurring.” Park mentions, as an example, that a doctor cannot provide a proper treatment to a patient unless the patient explains his or her physical problem correctly in detail. “Thus the supplier can offer the best product and solutions only when the customer presents its situation and problem clearly.” BUT SOLVING CUSTOMERS’

problems is not always easy. Park has a long experience in the metalworking industry, having spent

South Korea is one of the top players in the electronics, automobile, telecommunication and shipbuilding industries.

14 years at Seco and 14 years before that as a tool designer and milling product manager at Korea Tungsten, a manufacturer of cutting tools that was later renamed TaeguTec. Park has found transparency and empathy to be the best approaches to dealing with challenging situations: “I do my best to figure out the customer’s misunderstanding. If we are the party who makes a mistake, I offer an apology. If any difficult situation is initiated by

a customer’s misunderstanding, I then take time and explain the matter by providing a support document. I try to put myself in the customer’s position to understand them better.” Park says challenges should be approached both positively yet cautiously, with a strong reliance on responsibility. He never leaves work half-done, saying that he cannot concentrate on anything else until the first thing is finished. He likes to delegate, and when analysing situations he is open-minded, flexible and willing to try out new ideas. Nowadays, technology is moving fast, and Park sees changes ahead in terms of his job and the industry. “In my opinion, innovative software for the next generation processing industry is needed,” he says. “The current machinery processing industry must transfer its basis from hardware to software. This will enable us to download the application of cutting conditions for tools or any other application from the Web in real-time, allowing us to catch up with rapidly changing technical knowledge.”

olid tools mill, drill and thread in a wide variety of applications, with components ranging from dental implants and airplane turbine blades to connecting rods in cars. Technological advances demand constant refinement, which is why Seco instituted Product Centre Solid Tools (PCST). “PCST accelerates our developments in production, R&D and marketing in order to support the customer better in the future,” says Marketing Manager Johan Lahiri. About 10,000 different solid tools comprise Seco’s standard range, so the combinations between tools and applications are virtually infinite. New trends in machining keep changing the landscape, so most individual machining companies struggle to keep track of new developments on all fronts. This is where PCST can play a role. “Our objective is not just to sell more tools; it’s to help our customers become as successful as possible through a solution suited to their needs,” says Lahiri. “This is a win-win situation in which application know-how is key.” The considerations for selecting solid tools are many. For example, increasing unmanned

24 edge [2·2013]

production demands high tool reliability and predictable tool life. “If you set up a machine to run unmanned overnight and a tool breaks after just an hour, then productivity suffers. It is fundamental that the tools we provide have precisely the performance and quality we say they do,” says Lahiri, noting that PCST helps to assure this. The vehicle and aerospace industries fight a constant battle against weight to make their products as fuel-efficient as possible. “There is an increasing use of difficult-to-machine materials, such as superalloys, ceramics and composites, which are light-weight and strong,” says Lahiri. “We are constantly developing new tools with coatings and cutting geometries that can handle these.” At the same time, the shapes of machined components are getting more complex, with tighter tolerances. Solid tools can be made to precisely match these requirements. The need to protect the environment is also influencing machining all the way down to the machining strategy, where coolant is now being replaced with dry machining. Flexibility is another consideration, when one type of tool may be used in several applications and materials; this is especially important for general machining companies that are sub-contracted to handle small production series on short notice. Last but not least, having correct and updated information is critical. In the manufacturing sector this means easy access to dynamic cutting data, and machining professionals can find this support on the Web. “We have an application called ‘solid quote’, in which users can enter their own parameters to find out which tool they should use, what the price of the tool is and when it will be delivered,” says Lahiri.

Product Centre Solid Tools (PCST) was started by Seco in 2012. Its purpose is to streamline internal processes to shorten lead times and maximise delivery precision, but also to enhance the product quality and offering, and give the best possible customer support. Headquartered in Lottum, the Netherlands, the PCST organisation has 320 employees. Research, product development and manufacturing are concentrated in different locations, depending on the application. The Lottum facility has special responsibility for milling, together with Seco’s unit in Reynoldsville, USA. Drilling is based in Norrköping and threading in Fagersta, both located in Sweden. Reconditioning of used tools is also an important function, and sales support is executed through both a central and local organisation of application specialists.

No iron, no problem THE JABRO-SOLID2 range of solid end mills has been extended with the JS400 series for non-ferrous materials. Building on the success of the JS500 series for steels, stainless steels and cast irons, JS400 is designed for machining of aluminium and plastics. JS412 and JS413 are easy to use and suitable for users with low-speed or low-torque spindle machines, typically found in smaller workshops. JS452 and JS453 are tools in the high end made for efficient machining by first and second tier component suppliers. To meet their demand for maximum reliability and performance, chip evacuation must be perfect at all times. An important feature on the JS450 series is the specially shaped flute spacing that optimises exit of the chips, away from the critical cutting zone area. The new JS400 series will be replacing Jabro-VHM types J40, J99 and J93, offering up to thirty percent higher metal removal rate and tool life.

JABROTM SOLID2 CHAMFER TOOLS TWO NEW CHAMFER TOOLS have been included in the Jabro-Solid2 JS500 series. JS506 and JS509 are available with 90- or 60-degree tip angle. A high-quality carbide grade has been combined with the proven SIRON-A coating to ensure long tool life. The tools also feature uneven flute spacing, preventing chatter and vibration to create optimum surface quality of the workpiece. JS506 and JS509 are suitable for all materials found in the general machining segment and are a valuable add-on to the Seco Jabro product portfolio.

SECO’S JETSTREAM TOOLING® range achieves better productivity and chip control with precisely directed and focused coolant jets, from outlets just behind the cutting zone. Now, a new generation in this tool range for turning applications features the company’s P-holder lever design, replacing the earlier eccentric pin-locking. The P-holder uses a lever solution to offer more rigid locking of the insert and improved repeatability in the insert indexation. Better rigidity allows increased depths of cut, higher feed rates and improved part quality. In addition to the standard coolant inducer for finishing and medium-roughing, there is a new option for roughing. The P-holder is also designed with Jetstream Tooling® Duo cooling, where an additional coolant jet flushes the clearance surface. This additional coolant jet can increase tool life by another 10 percent and also improve the finish of the component. All holders in the new generation of Jetstream Tooling® are made for negative inserts and are available in shank and Seco-Capto versions.
