Why does the precision of precision metal parts deteriorate?


The accuracy of the hardware parts almost determines the quality of the product. The more precise the hardware parts, the higher the precision requirements, so why does the precision of precision metal parts deteriorate?

The first factor is the poor precision of the part itself. Generally speaking, if the dynamic error between the shafts is not adjusted during installation, or because the shaft drive chain changes due to wear, it will affect the accuracy of the parts. In general, the accuracy of the type of error can be corrected by re-adjusting the compensation amount. If the error is too large or even if an alarm occurs, it is necessary to check the servo motor to see if the speed is too high.

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

The third factor is that the roundness caused by the two-axis linkage is out of tolerance, the machine does not adjust the axial deformation of the circle, the screw gap compensation of the shaft is not correct, or the axis positioning is offset, and the precision of the precision parts may be Have an impact.
