[0002] The circumferential processing of shaft parts on machine tools is basically carried out through lathes. The first axial end of the shaft body needs to be clamped by a three-jaw or four-jaw chuck, and the other end is tightened by a push rod. The chuck and the push rod are then rotated, and the two carry the shaft body to rotate around its own axis, so that the tool can perform circumferential processing on the outer wall of the shaft body. The shaft body processing tooling is used during processing to position and clamp the shaft body.
