[0025] In this embodiment, the workpiece 3 is placed on the workpiece chuck 23, and the rotating motor 22 is started, and the workpiece 3 rotates accordingly. At the same time, the side grinding mechanism starts to work, and the lifting electric cylinder 25 drives the lifting seat 26 to move up and down to adapt to the workpieces 3 of different heights. Driven by the lifting seat 26, the clamping seat cylinder 27 makes the two clamping claws 28 clamp the two sides of the workpiece 3 to ensure that the workpiece 3 is stable and motionless during the grinding process. The side grinding strip 29 is close to the side of the workpiece 3, and the grinding of the side of the workpiece 3 is completed through relative movement.

[0026] Among them, a waste port 111 is set through the substrate 11 below the workpiece chuck 23, and a waste box 13 is set below the waste port 111. The waste box 13 is used to collect powder waste after grinding, and the waste box 13 is slidably connected to the substrate 11. Foot pads 14 are set at the corners of the bottom surface of the substrate 11.

[0027] In this embodiment, as the grinding process proceeds, the powder waste generated by grinding will fall into the waste box 13 through the waste port 111 below the workpiece chuck 23.
