What is the cause of the poor machining accuracy of parts?

- Nov 06, 2019-

Accuracy is very important for part processing, because it affects the final result, so if you want the final product to work well, then we must ensure that the accuracy is always correct. If the accuracy has changed, it must be corrected in time, but because there are more than one factor that affects the accuracy, we must know what is the cause of the accuracy before solving the problem. Let's take a look at the resulting machining accuracy. what is the reason?


Precision parts processing

First, the machining accuracy of the parts themselves is poor. 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.

Second, the overshoot of the machine tool 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.

Third, because the roundness caused by the two-axis linkage is out of tolerance, the machine does not adjust the axial deformation of the circle, the shaft gap compensation of the shaft is not correct or the axis positioning is offset, which may affect the precision of the precision parts.
