Why does the machining accuracy of precision parts deteriorate?

​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? The following is Brishine United Industry Co., Limited’s answer for everyone:





The first factor is the poor machining accuracy of the parts themselves. Generally speaking, if the dynamic error between the shafts is not adjusted well during installation, or because the shaft drive 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.

The second factor is that 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. Prolong the change time appropriately. 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 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 not correct or the shaft positioning is offset, which may affect the accuracy of the precision parts. Make an impact.
