Why does the accuracy of precision hardware parts deteriorate?

2022-09-25

The precision of hardware parts almost determines the quality of the product, and the higher the precision of hardware parts, the higher the requirement for precision. So, why does precision parts machining accuracy become worse?

First, the parts themselves are poorly machined. Generally speaking, if the dynamic error between the shafts is not well adjusted during installation or changes due to wear and tear of the shaft drive chain, the accuracy of the parts will be affected. Generally, the accuracy check caused by such errors can be solved by readjustment compensation. If the error is too large or even if there is an alarm, you need to check the servo motor and observe whether its speed is too high.

Second, machine tool overshoot during operation can also affect machining accuracy, which may be due to acceleration and deceleration time is too short, the replacement time is properly extended. Of course, it is also likely that the connection between the screw and the servo motor is loose.

Third, because of the two-axis linkage generated by the roundness overshoot, the machine is not properly adjusted to form the axial deformation of the circle, the axis of the screw clearance compensation is not correct or the axis positioning offset, which may affect the precision of precision parts.
