(2) How to use tooling
The positioning sleeve 2 is clamped by the lathe chuck 1 and the workpiece 3 is placed in the positioning sleeve 2, and the workpiece is correctly positioned by the taper hole of the positioning sleeve 2. Screw on the clamping nut 4, approximately 3 mm of the end face of the workpiece, and lock with a hook wrench. If there is a weld on the surface of the workpiece, the weld bead is aligned with the groove 6 in the positioning sleeve 2 when the workpiece is placed to ensure the positioning accuracy of the workpiece 3 within the positioning sleeve 2. In this process, the inner hole size, the axial size, the both end faces of the workpiece, and the inner chamfer can be processed.
