The precision of hardware parts almost determines the quality of the products. The more careful the hardware parts are, the higher the accuracy requirements will be. So what are the reasons for the drop of precision? Let’s have a simple understanding below:
One factor is the poor machining accuracy of the parts themselves. Generally speaking, if the dynamic deviation between shafts is not adjusted well during installation, it may also be because the shaft drive chain changes due to wear, which will affect the accuracy of the parts. Generally speaking, it is advisable to adjust the compensation amount from the beginning in order to check the accuracy caused by the deviation of this variety. If the deviation is too large and even if an alarm occurs, it is necessary to check the servo motor to see if its speed is too high.
The two factors are that the overshoot during the operation of the machine tool will also affect the processing accuracy. It is possible that the acceleration and deceleration time is too short, and the appropriate lengthening of the transition time. Of course, it is also very likely that the link between the lead screw and the servo motor is loose.
The three factors are the roundness out of tolerance caused by the linkage of the two shafts, the axial deformation of the circle caused by the mechanical failure, the compensation error of the screw clearance of the shaft, or the deviation of the shaft positioning, which may affect the precision of the detailed parts.
The above is the cause of precision drop, I hope to help you
