The precision of hardware parts almost determines the quality of products. The more precise hardware parts are, the higher the requirements for precision are. So why does the machining accuracy of precision parts become worse? Here are the answers for you:
Precision parts processing
1、 The factor is the poor machining accuracy of the part itself. Generally speaking, if the dynamic error between shafts is not adjusted well during installation, or changes due to the wear of shaft transmission chain, the accuracy of parts will be affected. Generally, the accuracy of text search caused by such errors can be adjusted to compensate for the amount of resolution. If the error is too large or even an alarm occurs, it is necessary to check the servo motor and observe whether its speed is too high.
2、 The factor is that excessive operation will also affect the machining accuracy of the machine tool. This may be because the acceleration and deceleration time is too short, and the appropriate expansion and change time. Of course, it is also very likely that the link between the lead screw and the servo motor is loose.
3、 The reason is that the roundness out of tolerance caused by the linkage of the two shafts, the axial deformation of the circle formed by the machinery is not adjusted properly, the lead screw clearance compensation of the shaft is not correct, or the shaft positioning is offset, which may affect the accuracy of precision parts.
