The precision of hardware parts almost determines the quality of the product, the more precision hardware parts of its precision requirements will be higher, then, why precision hardware parts processing accuracy will become worse?

1. The machining accuracy of the part itself is poor. Generally speaking, if the dynamic error between the shafts is not adjusted during installation, or because the shaft transmission chain changes due to wear will affect the accuracy of the parts.

Generally speaking, the accuracy caused by this type of error can be solved by readjusting the compensation amount. If the error is too large or even if an alarm is generated, it is necessary to check the servo motor to observe whether its speed is too high.

2. Overshoot of the machine tool during operation will also affect the machining accuracy. It may be because the acceleration and deceleration time is too short and the change time is appropriately prolonged. Of course, it is also most likely because the link between the screw and the servo motor is loose.

3. The roundness is out of tolerance due to the linkage of the two shafts, the mechanical failure to adjust the axial deformation of the circle, the incorrect screw clearance compensation of the shaft or the deviation of the shaft positioning may affect the accuracy of precision parts.
