solution

Thin wall cutting is easy to deform; The clamping force of the fixture is large, the end face will bulge out, and the clamping force is small. The shaving tool tip arc is small, the surface is not bright, the tool tip arc is large, the turning resistance is large, the parallelism is out of line and so on

Our solution results: 0.4 wall thickness we can meet the dimensional tolerance requirements, parallelism we control within 0.01, perpendicularity within 0.015, flatness within 0.015, concentricity within 0.01, surface brightness also meets customer requirements. The wall thickness we have challenged to 0.28+/-0.02

The three shaft eccentricity, end slotting and side machining threads are all completed in one machine at a time, which can ensure the offset of each eccentric shaft, the direction of slotting and side threads.
