General Mach Discussion / Turning UHMW Poly on CNC
« on: November 16, 2005, 08:22:15 PM »
"UHMW machines very easily to a smooth surface, but in lathe turnings come off as a long string that must be prevented from wrapping around the work piece.

Found the above quote on a source supplier for UHMW poly, and they are right, turnings do come off in a long string, But how would one prevent the swarf from wrapping around the work piece?  I'm using 1/4 HSS ground and polished, with a chip break groove, lots of relief clearance, front and sides. positive rake on the cutting tool. But the swarf wraps around the work in to a ball of what looks like fishing line.

I'm turning flanged bushings, 4 to 8 at a time using UHMW poly on a mach 3 controlled lathe.

Ideas on how to improve? links, help sites? tool design? feed rates, speed?
