[0002] Diamond grinding disc refers to a disc-type abrasive tool used in a grinding machine. It consists of a disc body and a diamond grinding block. The diamond is welded or embedded in the disc body. The high-speed rotation of the grinder is used to smoothen the working surface.

[0003] Before processing the diamond grinding wheel, a clamp is undoubtedly needed. The clamp can clamp and fix the outer surface of the workpiece. Commonly used clamps are usually two-way threaded rods or cylinders. After the two-way threaded rod is rotated, the clamp block is driven to move to clamp the outer surface of the workpiece. After the cylinder is extended, the clamp block is driven to move to clamp the outer surface of the workpiece. However, in this process, the outer surface of the workpiece is clamped in two directions, such as left and right directions or front and back directions. After the processing device processes the workpiece, as the processing device moves, it has a certain thrust on the workpiece.
