| Abstract: | Ball screw is very important part in the NC machine tool feed system. Its performance directly affects the positioning accuracy of feed system. This article calculated the stiffness of ball screw by theoretical calculation and ANSYS simulation, to analyze the influence of the torsion stiffness and axial stiffness on the loss of momentum. It provides reliable reference for the structural design of feed system and the improvement of positioning accuracy of feed system. |
