Why does the accuracy of precision parts deteriorate?
Author：
The precision of the hardware parts almost determines the quality of the product, the more precise the hardware parts its precision requirements will be higher, then the precision of hardware parts processing why it will become worse? The following answers for everyone.
The first factor is the poor machining accuracy of the parts themselves, generally speaking, if the dynamic error between the shaft is not well adjusted at the time of installation, or because the shaft drive chain changes because of wear will affect the accuracy of the parts. Generally speaking, this type of error caused by the accuracy of the chapter can be re-adjusted compensation amount to solve. If the error is too large or even if the alarm is generated, it is necessary to check the servo motor to observe whether its speed is too high.
The second factor is the machine tool in operation overshoot will also affect the processing accuracy, possibly because the acceleration and deceleration time is too short, the appropriate extension of the change time, of course, is also very likely because the link between the screw and the servo motor is loose.
The third factor is because of the two-axis linkage generated by the roundness of the ultra poor, mechanical is not adjusted to form a circle of axial deformation, the axis of the screw gap compensation is not correct or shaft positioning offset, may have an impact on the accuracy of precision parts.
