Boring Or Reaming – Which Procedure To Choose?
After a hole has been drilled, there are two great techniques to complete it to the proper size: boring and reaming. Although each of these procedures has a unique specialty, they both assist in meeting the high tolerance and finish standards for hole making. In the blog post that follows, we’ll discuss each of these methods from a variety of angles to help you choose which one is best for your specific application and demand.
How the hole is roughed up initially
Following drilling, it is necessary to bore and ream. The method that will be more practical to utilise for completing the hole will now be mostly determined by how the drilling procedure roughed out the hole. For instance, both reaming and boring can result in the necessary geometries if the hole is suitably roughed. Nonetheless, boring bars are more practical than reamers, as the former can feed straighter, while the latter having a tendency to balance the flutes and only follow the pre-hole.
Dimensions required
When deciding whether to use boring or reaming to finish your hole, the needed hole diameter may have some limits. At an 8 inch bore and higher, for example, reamers are quite hard to come by. Similar difficulties arise when trying to locate a boring head for small holes. Hence, reamers are best for finishing smaller holes, whereas boring is the best choice for finishing bigger holes.
Surface finish requirements
Because boring bars have virtually endless options for insert shape, feed rate, and corner radius, they are a superior option if there are certain surface finish criteria to meet, such as minimum or maximum requirements. Reamers may or may not be able to offer the same, but they are unquestionably an option for aesthetic appeal.
Material to be cut
Hole drilling and finishing may be necessary for a number of materials. What kind of substance are you using? The material you want to make a hole in has a significant impact on a number of factors, including the estimated tool life, the requirement for backup tools, the cost per part, the roughing conditions, the quality of the surface finish, and the ability to maintain size and geometric tolerances. Reamers can function effectively when the holes are appropriately roughed, but they may chip easily if the holes have cross-holes or other interruptions. Boring would be a much better choice in this situation.
Volume of the project
A boring technique can be a simple solution for finishing fewer holes because it requires fewer tools and offers more flexibility. However, as order volumes rise, new factors like as backup tools, tool life, and cycle time must be taken into account. Reamers may be helpful in this situation because of their improved cycle time, more flutes, and faster feeds.
Operator experience
Last but not least, your operator is best suited to choose the procedure with which he is most at ease. For instance, compared to a boring bar, a specialpurpose guide pad reamer can typically be very challenging to set up. An operator can eventually become proficient at it with experience, but lengthy setups reduce vital spindle uptime. You should be able to choose whatever method you wish to use for your operation based on the time you have available and the experience your operator has with boring and reaming operations.
As can be seen, boring is a superior solution for any type of roughed hole, large diameter hole, and surface finishing requirements, being only limited to the volume of the project that can be accomplished in one go. Hence, boring can prove to be a far more practical option for you than reaming if this particular issue is not actually a concern for you. This is when you’ll search for boring tool manufacturers who can give you the appropriate equipment. From boring bars
