How to deal with hole chamfering of shaft body

On the lathe, the right end of the shaft is generally supported by the center frame for chamfering the hole of the shaft body.

Operation process:

1. Put the middle frame on the bed and open it.

2. Clamp the shaft on the three claws and jack up the other end (right end) with the end of the bed.

3. Put the center frame on the right end of the shaft, and three supporting claws hold the shaft, and ensure that the center frame is coaxial with the rotation center of the lathe spindle (if the shaft is different, no matter how tightly you clamp it, the workpiece will run out by itself).

4. Install the center frame, return to the end of the bed, and then chamfer with oil.
