CNC-machining precious plastic
I’ve been doing some quick testing on cnc-machining plastic created with the extrusion machine made by using the technique which has been discussed in this topic. I thought I’d share my results here and post later tests and experiments here as well.
The type I did the first tests on was PP (5) and gives nice and promising results! Machining goes very smooth using a single flute upcut, 18000 rpm and a feedrate of 25 mm/s. The only downside is that I now sometimes get some white burrs from the plastic. But quickly going over it with a heat gun gets rid of those.
More tests coming soon.
