Talking about why the machining accuracy of precision hardware parts deteriorates?
The accuracy of hardware parts almost determines the quality of the product. The more precise the hardware parts, the higher the accuracy requirements will be, so why does the precision of the precision hardware parts become worse? Let's briefly analyze it for everyone below.
First, the machining accuracy of the parts itself is poor. Generally speaking, if the dynamic error between the shafts is not adjusted properly during installation, or because the shaft transmission chain changes due to wear, the accuracy of the parts will be affected. Generally speaking, the accuracy check caused by this type of error can be solved 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 its 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 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.
3. The roundness caused by the two-axis linkage is out of tolerance, the machine is not adjusted properly to form a circular axial deformation, the screw clearance compensation of the shaft is incorrect or the shaft positioning is offset, which may affect the accuracy of the precision parts. .Previous: Introduction to precision metal processing technology and operation specifications ？Next: Where are the advantages of precision metal processing?
