The precision of hardware parts almost determines the quality of products. The more precise the hardware parts are, the higher the precision requirements will be. So why does the precision of precision hardware parts become worse? Here are the answers for you:
The first factor is the poor machining accuracy of the part itself. Generally speaking, if the dynamic error between shafts is not adjusted properly during installation, or the shaft transmission chain changes due to wear, the accuracy of the part 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 and observe whether its speed is too high.
The second factor is that the overshoot of the 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 the lead screw and the servo motor is loose.
The third factor is that the roundness caused by the linkage of two shafts is out of tolerance, the machinery is not adjusted properly to form the axial deformation of the circle, the clearance compensation of the shaft lead screw is not correct, or the shaft positioning is offset, which may affect the precision of precision parts.
