I am looking at uprating my spindle so i have at least 60000rpm available as all the feeds and speeds are saying i require more speed.
I want to 3d mill molds in aluminium, and up to press have only used corian and the machine is fine for that. I have added a hench fog buster so chip clearance and cooling should be no problem.
I wondered if anyone machines anything similar that could give me some pointers.
