Ball screws are used in the feed systems of the Numerical Control (NC) machines tools working with constantly higher cutting speed. When the speed of the balls reaches certain level, the repetitive shocks (impact forces) generated by the balls in the "transient" phase of the balls' motion increases vibration and noise. The frequency of impact forces should not be equal to the resonance frequency of driving system. Otherwise it could cause an incorrect work of the system, even could damage the ball screw mechanism. Digital simulation of these forces for definite screw and ball diameters in function of rotational speed has been investigated. The feed system resonance frequency for variable payload masses, balls diameters and the ball screw shafts length has been examined.
