It depends on the motors, and the machine. Remember, the "pros"
are running 1200 IPM, 10+ G's acceleration, 25+ Hp 25000 RPM
spindles, etc.

Depending on the drive mechanism, your motors may or not be required
to turn at these rates. Tell us what drive you will use, and what
maximum feedrate you expect to need. Then, we can advise.
