Good Plastic For Machining

Polishing methods are direct machine polish vapor polish flame polish and buffing.

Good plastic for machining.

3d printing is a more recent but rapidly maturing set of technologies opening up to a wider range of low to mid volume. 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. 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. We re looking for some hard plastic for some fixturing that will support some thin wall parts during machining.

Essentially the plastic will act as plugs but it needs to be really precise in overall length and diameter. Their precision rigidity and power output allow them to process even hardened plastics with ease. Acetal peek and pvc plastic materials have superior machining characteristics plus they resist melting and chipping while offering good dimensional stability. Loading strength psi tensile strength plastic in tension and compression strength plastic under compression are important values for structural applications.

Drawbacks the downside to delrin s slippery wear resistant surface is that it s very hard to glue. Our first thoughts are nylon. All the machine tools used to cut plastic are actually metal machining tools. 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.
