Good Plastic For Machining

Drawbacks the downside to delrin s slippery wear resistant surface is that it s very hard to glue.

Good plastic for machining.

All the machine tools used to cut plastic are actually metal machining tools. 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. Their precision rigidity and power output allow them to process even hardened plastics with ease. Polishing methods are direct machine polish vapor polish flame polish and buffing.

Our first thoughts are nylon. Loading strength psi tensile strength plastic in tension and compression strength plastic under compression are important values for structural applications. 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. 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.

I should note that woodworking machine tools won t do as good of a job though since their rigidity is lower. We want something that handles threaded and or tapped holes nicely. Acetal peek and pvc plastic materials have superior machining characteristics plus they resist melting and chipping while offering good dimensional stability. Essentially the plastic will act as plugs but it needs to be really precise in overall length and diameter.
