The phase light of the driver is normal, and the size of the processed workpiece is large and small
Cause: the long-term high-speed operation of the machine tool carriage leads to the wear of the screw rod and bearing. The repeated positioning accuracy of the tool holder deviates during long-term use. The carriage can accurately return to the processing starting point every time, but the size of the processed workpiece still changes. This phenomenon is generally caused by the spindle. The high-speed rotation of the spindle makes the bearing wear seriously, resulting in the change of machining size.
