First, adjust the feed mechanism to improve the CNC lathe machining accuracy
First, the accuracy of CNC lathe machining caused by the lead error of the ball screw is affected. The factors that affect this are mainly pulses. Therefore, in the process of manufacturing the ball screw, it is necessary to minimize the error and cause the pulse pair to be reduced. CNC lathe machining accuracy.
Secondly, the effect of gaps in the feeding mechanism on the machining accuracy of CNC lathes is mainly due to the problems caused by the problems in the components of the transmission machinery, thereby reducing the accuracy of the uncontrolled lathe processing. The main components are gears, couplings, ball screws and support shafts. The problems that arise between these components will affect the machining accuracy of CNC machine tools, so we must strengthen the connectivity between their structures. The precision between them will affect the accuracy of lathe processing, thereby reducing the gap between the various structures, and strengthening the tightness between the various structures will improve the accuracy of CNC lathe machining.
Second, the impact of errors in programming
The difference between CNC lathes and ordinary lathes is that the accuracy of the parts is different, but the errors that occur in the programming process can be minimized, which requires us to reduce the error from several aspects, thereby improving the CNC lathe processing Accuracy.
The first is due to the influence of interpolation error on the accuracy of the lathe. Therefore, it is necessary to use certain methods to reduce programming problems, use absolute programming, and eliminate the error by using the reference point quality to program the program.
Second, the impact of the error on the final accuracy is approximated. Since there are approximations in the process, errors occur. Therefore, to master the profile equation as much as possible to reduce errors when programming, this can eliminate the impact on the accuracy of CNC lathe processing;
Thirdly, because of rounding error, the machining accuracy of the CNC lathe is reduced during the programming process. Therefore, we must select the minimum value of the linear displacement determined by the pulse equivalent to be used for reference when machining. Therefore, when programming, it is necessary to strictly follow the specifications above the drawings as a benchmark
