Hello,

I am putting together a CNC milling system to make some prototype enclosure from plastic (Perspex for the time being) the system is based on an X2 with a bolt on CNC kit and I shall uses the Mach3 software to drive the mill.

So my question is what sort of end mills do I need please 1, 2, 3 or 4 flute and what sort of rotational speed and feed rates are best for doing plastics milling?

Many thanks
