The accuracy of hardware parts almost determines the quality of the product. The more precise the hardware parts, the higher the requirements for accuracy. So why does the machining accuracy of precision parts deteriorate? Here is the answer given by RFC PRECISION MACHINE:
First, the factor is that the machining accuracy of the part itself is poor. Generally speaking, if the dynamic error between the shafts is not adjusted well during the installation process, or changes due to the wear of the shaft transmission chain, it will affect the accuracy of the parts. In general, the accuracy of text searches caused by such errors can be adjusted to compensate for the amount of resolution. If the error is too large or even an alarm occurs, it is necessary to check the servo motor to observe whether its speed is too high.
Second, the factor is that excessive operation will also affect the machining accuracy of the machine tool. This may be because the acceleration and deceleration time is too short, and the time for appropriate expansion changes. Of course, it is also very likely that the connection between the lead screw and the servo motor is loose.
- The factor is that the roundness caused by the linkage of the two shafts is out of tolerance, the machine is not adjusted well to form the axial deformation of the circle, the compensation of the screw clearance of the shaft is incorrect or the shaft positioning is offset, which may affect the accuracy of the precision parts. Influence.
