Accuracy is very important for parts processing, because it affects the final results of the problem, so want to make the final product effect is good, then we have to ensure that the accuracy is always correct. If the accuracy has changed, then we must correct it in time, but because there is more than one factor affecting the accuracy, before solving the problem must know what is the cause of the impact on the accuracy, the following we will understand what causes the parts machining accuracy deterioration is?
First, the parts themselves are poorly machined, generally speaking, if the dynamic error between the shafts is not well adjusted at the time of installation, or because the shaft drive chain changes due to wear will affect the accuracy of the parts. Generally speaking, this type of error caused by the accuracy of the chapter can be re-adjusted compensation amount to solve. And if the error is too large or even if the alarm is generated, it is necessary to check the servo motor, observe whether its speed is too high.
Second, the machine tool in operation overshoot will also affect the processing accuracy, possibly because the acceleration and deceleration time is too short, the appropriate extension of the change time, of course, is also very likely because the link between the screw and servo motor loosening.
Third, because of the two-axis linkage generated by the roundness of the overshoot, the machinery is not adjusted to form a circle of axial deformation, the axis of the screw gap compensation is not correct or shaft positioning offset, may have an impact on the accuracy of precision parts.
These points are the reasons that lead to poor machining accuracy of the parts, now the more precision parts on the higher the requirements of precision, so we must pay attention to this aspect of the problem, so today we will first talk about it!
