I have patiently been waiting for / looking for the right used VMC to be used for protoyping in Aluminum (Mold and Pattern work actually). I found an Okuma MC-v4020, but it has an 8000 RPM Spindle. I was really set on a 12000 or 15000 RPM Spindle. With the bulk of my work being aluminum molds, is it even worth considering 8000 RPM?
I do plan on using a coolant driven high speed spindle (Colibir / SpinJet / Etc...) for finishing (40,000 RPM...1/32" to 3/32" tools ). With a 40K spindle, perhaps semi-roughing using a 3/32 tool would be a viable intermediate step.
