Full speed CNC plastic mill - small production/prototype run

[@cncproduct9505]

Face mill could save you a ton of time...

[@eIektrinis]

only if you have a tool changer and if your part has no features up to top face, which it does.

why no coolent in high speed?

[@pargyropoulos]

you don't climb mill, that's why you don't have clean results...

[@eIektrinis]

Climb mill is preferred for better tool life and speed, due to more uniform chip chickness. For cleanliness, especially in plastics, conventional milling is better. At least on my machines.

circuitdotlt I've never had good results with convetional milling on plastics. Try a two flute upward spiral bit and climb milling on plastic or acrylic and you'll notice the differnce. Your bit looks like a straight one.
