A grinding assembly is also arranged at one end of the workbench 1 away from the second motor 8.

[0025] During actual use, the workbench 1 provides stable support for the support plate 2. At first, the distance between the two groups of first sliders 6 is large, and the second slider 7 is set at the end away from the grinding assembly. The first motor 3 is started, and the first motor 3 drives the forward and reverse screws 4 to rotate. The two groups of first sliders 6 drive the support frame 9 to move toward each other to limit the edge of the material. Then the second motor 8 is started, and the second motor 8 drives the first threaded rod 5 to rotate. After the second slider 7 contacts the material, it pushes the material to complete the feeding, ensuring that the edge of the material protrudes from the support plate 2, and then the material is further clamped by the auxiliary positioning assembly to ensure its fixed stability, and then the material is ground by the grinding assembly.

[0026] In this embodiment, the auxiliary positioning member includes a bolt 10, a bearing 11, a lower pressure plate 12 and a first guide rod 13.
