Classification of axes

Shafts shall be divided into high-precision ones and general ones. The high-precision ones shall be jacked up at both ends of the central hole, so as to ensure the concentricity of each gear of the shaft. It is also conducive to grinding machine processing in the next process. The center frame shall be used for the long shaft and a knife rest shall be used for the thin shaft. For general requirements, a three jaw chuck clamp can be used at one end. Processing method of a head item.

Disc parts are installed and processed with three jaw chuck or tooling fixture.

Sleeve parts are like rough machining with high centricity requirements. Finish the inner hole first, and then use the mandrel sleeve to process the outer circle.

Special fixtures shall be used for special-purpose clamping to complete the machining.
