The accuracy of hardware parts almost determines the quality of the product. The more precise the hardware parts, the higher the accuracy requirements will be. So why does the machining accuracy of precision hardware parts deteriorate?

1. The factor is that the machining accuracy of the part itself is poor. Generally speaking, if the dynamic error between the shafts is not adjusted well during installation, or because the shaft transmission chain changes due to wear, the accuracy of the parts will be affected. Generally speaking, the accuracy check 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 occurs, it is necessary to check the servo motor to observe whether its speed is too high.

2. The factor is that the 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 should be appropriately extended. Of course, it is also likely because the connection between the screw and the servo motor is loose.

3. The factor is that the roundness caused by the linkage of the two axes is out of tolerance, the machine is not adjusted well to form the axial deformation of the circle, the compensation of the lead screw gap of the axis is not correct or the axis positioning is offset, which may affect the accuracy of the precision parts. influences.
