Diamond grinding disc

Abstract

This invention discloses a diamond grinding disc with high bonding strength and good discharge effect, belonging to the technical field of grinding tools. The inner ring of the grinding disc substrate has teardrop-shaped discharge holes A. Multiple sets of diamond grinding blocks are provided, each set consisting of two L-shaped grinding blocks arranged opposite each other. A gap is left between the two L-shaped grinding blocks in each set to form a discharge groove, and discharge holes B are opened on the substrate corresponding to the discharge groove. The raw materials of the grinding blocks are composed of metal powders such as copper, iron, tin, cobalt, nickel, and phosphor bronze alloys, as well as diamond and liquid paraffin. Through the optimized design of the cutting head and substrate, this invention provides more chip removal holes on the contact surface of the grinding disc during grinding. This allows for the removal of more sand and dust when cutting concrete and granite. The heat generated during grinding is also carried away more easily with the flow of sand and dust, thus reducing the risk of the grinding disc cutting head overheating and burning, which could affect its use.
