| Abstract: | The transmission system of the NC machine tools is commonly with ball screw pairs, and the ball screw pairs in the manufacturing and assembly cause errors. The pitch error compensation of the axis of the ball screws of machines can ob- viously improve the positioning precision and positioning accuracy of the machine tools and thus greatly improve the machi- ning accuracy of NC machine tools. |
