Abstract
The setting of the pre-loaded force of ball screw nuts and bearings as elements of the feed kinematic linkage of the numerical control machine tools, has been done on a mathematical basis that eliminates the optimal pre-loading rate be constructed in different ways. This is possible after determining the aspect of the force deformation curve and its approximation to a curve that can be expressed analytically.
