How to select the precision of ball screws? Ball screws are widely used in machine tools. The appropriate type can be selected according to the application. Common circulation types of ball screws include internal circulation and external circulation. What practical tips are there for choosing the precision of ball screws?

1. When selecting screw precision, ensure it meets the positioning accuracy requirements of the main machine. Generally, the total travel error of the ball screw should be about 30% of the positioning error of the main machine.

2. For ball screws with the same dimensions and specifications, upgrading to a higher precision class will increase costs and extend the processing cycle.

3. For precision machine tools, the influence of thermal deformation of the entire system on the accuracy of the screw and guideway must be considered. Applying an appropriate preload can compensate for the thermal deformation of the screw.
