Hey Guys,

I'm an apprentice mold maker doing work with vacuum forming and rotomold tooling. Our facility currently uses Milltronic machines. We have 3 machines with a 5000RPM max and one with a 8000RPM max. I know the ones with a 5000RPM max is a huge.....er.....hurdle. I use Surfcam for our 3D programming (.0004 surface tolerance, .003 stepover-in order to get the molds out of the machine in a decent time) But there seems to be quite a bit of tooling marks in the finish. I was thinking of adding a nylon bristle brush and doing a planar cut on the finished vacuum mold.

Does anyone else use this nylon brush trick? Or any other tricks to help cut down on hand polishing? Thanks!

Matt
