First, the movement is stable
The ball screw drive system is a point contact rolling motion, which has small frictional resistance, high sensitivity, no chattering at start-up, and no creep at low speed, so the micro-feed can be precisely controlled.
Second, the transmission efficiency is high
The transmission efficiency of the ball screw drive system is as high as 90%~98%, which is 2~4 times that of the traditional sliding screw system. For example, it can get a large thrust with a small torque, and can also be rotated from a linear motion to a rotary motion. Exercise (reversible movement).
Third, high precision
The ball screw drive system has a small temperature rise during movement, and can pre-tighten the axial clearance and pre-stretch the lead screw to compensate for the thermal elongation, so that high positioning accuracy and repeated positioning accuracy can be obtained.
Fourth, good synchronization
