1. Ball screw: Its main function is to convert rotary motion into linear motion or convert torque into axial repeated force, and it has the characteristics of high precision, reversibility, and high efficiency.
2. Grinding ball screw accuracy grade: C0, C1, C2, C3, C5, and C7.
Rolled ball screws accuracy grade: C7 and C10.
3. Features of ball screw:
a. Small friction loss and high transmission efficiency;
b. High precision;
C. High-speed feed and micro-feed are possible;
d. High axial rigidity: The ball screws can be preloaded, and the axial clearance can reach a negative value due to the preloaded degree, thereby obtaining higher rigidity.
