Causes of Out-of-tolerance of Coaxiality and Verticality of Sleeve Workpiece
The reason why the coaxiality and verticality of the sleeve workpiece are out of tolerance is that the rotation axis of the workpiece does not coincide with that of the turntable. Coaxiality and verticality of sleeve-like workpieces, and the rotation axis of the workpiece do not coincide with the rotation axis of the turntable, resulting in out-of-tolerance. When making the fixture, due to machining errors, the rotating shaft and the rotating shaft of the turntable after clamping and positioning exceed the design requirements of the drawings, and the debugging personnel set the coordinate system instead of the rotating center of the turntable.
