If you Google for "critical speed calculator", you will find a number of sites where you can plug in your dimensions and check for max speed. They all give slightly different answers but you will get a good idea of what might be possible. Then you can play with different lengths, motor/screw gearing, etc, to meet your needs. For example, my machine is configured more for acceleration than speed as I do a lot of fine work where I seldom hit maximum speed anyway.
