Ball rail structure

- Jan 11, 2019-

The guide rail uses the ball as the rolling element, and has good motion sensitivity and high positioning degree; however, its bearing capacity and rigidity are small, and it is generally required to improve the bearing capacity and rigidity by pre-tightening. In order to avoid the loss of precision by pressing the pits on the guide rails, the guide rail faces are generally made of hardened steel. The ball guide is suitable for CNC machine tools with small moving parts and small cutting force.
