Usually these aspects should be done: 1. Try to reduce the number of clamping, and it is best to complete the clamping at one time.

2. Try to use a knife to process parts with coaxiality requirements.

3. The easily deformed parts should move slowly to reduce the stress on the workpiece. If the lathe had better turn in the opposite direction, pull (the tool turns from the spindle position to the spindle direction) to turn.

4. The turning tool tip must be the same height as the spindle, otherwise it will seriously affect the coaxiality.

In addition, special situations and special solutions are generally based on the above aspects.
