Manufacturing miniature parts and features is not new. In the past, EDM and laser technologies were used to create these features. Although these technologies worked for low volume jobs, they are not practical for the high volume micro applications that are in demand today.
The return on investment from digital boring comes from the time saved making adjustments on the spindle, as well as the increased adjustment accuracy.
When that inevitable job arises that requires higher RPM output, operators are left with the choice of replacing the machine altogether to gain higher productivity, or looking into an attachment, like a spindle speeder, to close the RPM gap.
When it comes to boring, there are several factors that can lead to poor performance. Whether it’s long cycle times, short tool life or poor bore quality, any or all these factors may need to be addressed in order to increase productivity. Although different, these issues are often closely linked in a given application.
Five-axis roughing can be painstaking. Pairing the right holder with the right cutter can save serious time while cutting and when setting up -- and eliminate those pain points.
When it comes to dialing in an ER system’s performance to match a specific application’s requirements or long life, there are three components to consider: the collet, the body of the holder and the nut.
Hi-Jet Holder TG Collet Type tool holder is capable of supplying coolant through or around the tool. Reduced heat generation greatly extends tool life.
With a little knowhow and the right tools, see how you can significantly reduce cycle time by rough boring instead of performing a helical interpolation with a mill.
