3. The existing clamp for machining the end face of the motor shaft needs manual clamping replacement and manual positioning in the production and machining process, and scraps on the surface of the clamp need to be manually cleaned after machining is finished. The process not only requires manual labor with high intensity, but also is not beneficial to automatic production.
