Machining UHMW – Points to Consider

Posted by Dave Biering

May 1, 2012

A customer recently asked us for tips on machining UHMW materials to better hold tolerances. UHMW is a very unstable material to machine, since it has roughly 12x the thermal expansion of steel. 

Some of the key factors that we like to review include the size and geometry of the part, the speeds and feeds of the machine, plus the types of coolants to use (and those to avoid). With the right technique in place, chipping, threading and other challenges can be avoided. 

We’ve created a video to provide even more machining tips. Or our in-house machining experts are always available to help you troubleshoot, and can point you to our “Machining Plastics" seminar.
