Why does the machining accuracy of precision metal parts deteriorate?

     With the continuous improvement of current science and technology, our technicians can know that there are many more processed products around us, or processing technology, and the processing of metal parts is the same, so why the precision of precision metal parts Will get worse?

    The first factor is the poor machining accuracy of the part itself. Generally speaking, if the dynamic error between the shafts is not adjusted properly during the time of the device, 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 readjust the compensation amount processing. If the error is too large or even if an alarm occurs, it is necessary to stop the inspection of the servo motor to see if its speed is too high.

    The second element is that the overshoot of the machine tool during operation will also affect the machining accuracy. It may be due to the too short acceleration and deceleration time. 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 the axial deformation of the circle, the screw gap compensation of the shaft is not correct, or the shaft positioning is offset, which may affect the accuracy of fine parts. Make an impact.
