Good plastic for machining.

I should note that woodworking machine tools won t do as good of a job though since their rigidity is lower. Essentially the plastic will act as plugs but it needs to be really precise in overall length and diameter. Plastic machining guidelines plastics generally allow for higher feed rates and create less wear and tear on machines and cutting bits as compared with metals. 3d printing is a more recent but rapidly maturing set of technologies opening up to a wider range of low to mid volume.

Our first thoughts are nylon. We want something that handles threaded and or tapped holes nicely. Their precision rigidity and power output allow them to process even hardened plastics with ease. Plastic manufacturing processes are constantly evolving and the inflection points where it makes sense to move from one technique to another are shifting due to improvements in equipment materials and economies of scale.

Delrin is a good plastic for these or any other applications that will experience lots of friction require tight tolerances or need a high stiffness material. Polishing methods are direct machine polish vapor polish flame polish and buffing. Acetal peek and pvc plastic materials have superior machining characteristics plus they resist melting and chipping while offering good dimensional stability. We re looking for some hard plastic for some fixturing that will support some thin wall parts during machining.
