1. The factor is the poor machining accuracy of the parts themselves. Generally speaking, if the dynamic error between shafts is not adjusted properly during installation, or because the shaft drive chain changes due to wear, the accuracy of the parts will be affected. Generally speaking, the precision search caused by this type of error can be solved by readjusting the compensation amount. If the error is too large, or even if there is an alarm, it is necessary to check the servo motor to see if its speed is too high.
2. The factor is that the machine tool will also affect the processing accuracy when it is running. It may be that the acceleration and deceleration time is too short, and the change time is appropriately extended. Of course, it is also likely that the connection between the lead screw and the servo motor is loose.
3. The factors are the out of tolerance roundness caused by the linkage of two shafts, the axial deformation of a circle caused by the machinery not being adjusted properly, the wrong compensation of the lead screw clearance of the shaft or the offset of the shaft positioning, which may affect the precision of precision parts.
