Ball screw difference 1 --- ordinary life. Rolling friction surface damage is much smaller than sliding friction, so when cleaning, lubricating and other conditions are met, ball mill, much higher than the ball screw trapezoidal screw sustain life. 2 --- self-locking. Self-locking and transmission efficiency is generally inversely proportional to Qinghai ball screws, therefore, almost no self-locking ball screw, lead screw and a certain self-locking (depending on the size of the lead angle and the working surface roughness) . Ball (ball screw) are widely used in precision machine tools, robotics, semiconductor, woodworking machinery, food machinery, medical equipment, optical instruments, glass manufacturing equipment, automotive equipment, automation equipment, laser engraving, blankets, machinery, ceramic tile machinery , printing machinery, electronics, wood-based panel machinery, paper machinery, positioning carrying devices, plastics machinery, inspection equipment, fans, conveyor (manufactured transport) equipment, engineering machinery, packaging machinery, textile machinery, washing machines, stamping machines, semiconductor manufacturing equipment, heavy-duty brakes, industrial machinery, forging machinery.
