The longer the screw the harder it is to compensate for deflection and you'll need more rigidity which limits speed. Example of a calculation for temperature, vibration and inertia with the "Dn factor": d0 × n ≤ Dn (d0 = ball-screw nominal diameter (mm) and n = speed in rpm) *Bonus did you know: Heat, like sound, is a form of kinetic ...

Ball screws make the machine too "slippery" to me for lack of a better term. There is no servo holding the screw on a manual and creeping up on a number is easier with the built in inefficiency of the acme. I did think it a great idea once, threw the ball-screws away and went back. Everyone on the floor hated it so dumpster bound.
