Treatment method of uneven wear of ball screw

The ball screw will wear out during use, but the wear is not necessarily uniform. Today, I will explain how to deal with the uneven wear of the ball screw. The correct approach is to replace all balls immediately. The method is to purchase 2 to 3 times the number of balls according to the required specifications and accuracy levels, measure all the balls with a micrometer, and group them according to the measurement results, and then select the balls with the size and shape tolerances within the allowable range. Perform assembly and preload adjustment. The accuracy and size consistency of the balls should meet the requirements.
