UHMW (Ultra high molecular weight Polyethelene) is giving me a bad part off. I've tried many different speeds and feed combinations, but cannot clean up the part off. I have to make 3000 more and its just gonna be a pain removing that as a secondary operation. If anybody has any type of suggestion for the parting off that would be greatly appreciated. Also, if you have a suggestion on how to remove of the excess parting material shown in picture efficiently please let me know (already made 2500). Thank you
