What are the factors affecting the machining accuracy of precision hardware parts?

The precision of precision hardware parts almost determines the quality of products. The more precise the hardware parts are, the higher the precision requirements will be. What are the factors affecting the precision of precision hardware parts?

1. The machining accuracy of parts is poor. Generally speaking, if the dynamic error between shafts is not adjusted well during installation, or because the shaft transmission chain changes due to wear, the accuracy of parts will be affected. Generally speaking, the accuracy check caused by this type of error can be solved by readjusting the compensation. If the error is too large, or even if an alarm occurs, it is necessary to check the servo motor and observe whether its speed is too high.

2. The overshoot of precision hardware parts processing machine tool during operation will also affect the processing accuracy. It may be because the acceleration and deceleration time is too short and the change time is appropriately extended. Of course, it is also very likely that the link between lead screw and servo motor is loose.

3. Because the roundness caused by the linkage of the two shafts is out of tolerance, the machinery is not properly adjusted to form the axial deformation of the circle, the lead screw clearance compensation of the shaft is not correct, or the shaft positioning is offset, which may affect the accuracy of precision parts.
