I'm looking to a servo press with force cca 10 kN. The price of complete presses are far above my budget, so I'm considering what's my options to build one. The frame of the press will not be a subject here, but only the main part of it - servo linear ball screw actuator.
I know the servo presses of similar power consist of a ball screw, gear pack, and of course a servo motor.
The question is: what's the math behind it? I think I seen somewhere that 10 kN servo presses use a 750 W AC servo drive. I would like to know which gear pack and ballscrew diameter would be good to go?
