When turning, CNC machining of custom center shaft workpieces encounters problems with accuracy and appearance roughness not meeting requirements. Based on the actual process during custom pin machining, analysis is performed.
1. Reasons and solutions for dimensional accuracy non-conformity
1. Due to operator carelessness, CNC machining errors during childhood, or errors in the dial, improper use
Therefore, the correct use of the dial is very important in the measurement process. As far as the middle pallet rocker dial is concerned, the dials of various lathes are different, and each small grid dial can be calculated by the following formula.
Turning tool moving pitch = screw pitch of the support plate / scale dial total dials (mm)
CNC precision parts processing to understand the value of each grid scale in the future, in the application also pay attention to because of the gap between the screw and the nut, sometimes the dial although the flip, but the turning tool does not necessarily move, and so the gap turned in the future before the turning tool moved. Therefore, in the application, if the scale turns off too many frames, it is never allowed to reverse only a few frames, but to reverse the future, and then align the scale from the beginning.
