Summary
CNC machine tool using ball screw as servo drive components, what are the advantages


The advantages of ball screw are:

(1) The rolling friction coefficient is small, the transmission efficiency is high, the efficiency can reach more than 90%, the friction coefficient f= 0.002 ~ 0.005;
(2) The friction coefficient has little relationship with speed, so the starting torque is close to the running torque, and the work is more stable;
(3) Small wear and long life, adjustable device can be used to adjust the gap, transmission accuracy and stiffness are improved;
(4) does not have self-locking, can change the linear motion into rotary motion.
Disadvantages of ball screw are:
(1) Complex structure and difficult manufacturing;
(2) In the mechanism that needs to prevent reversal, a self-locking mechanism should be added;
(3) The bearing capacity is not as large as the sliding screw transmission.
