Novel diamond grinding wheel

The utility model discloses a novel diamond grinding wheel which comprises a grinding wheel base body and a base, the grinding wheel base body is bonded on the base through metal, the grinding wheel base body is of a cylinder structure, the face, away from the base, of the grinding wheel base body is a grinding face, and the thickness of the grinding face is gradually reduced from the center of the grinding wheel base body to the edge direction. A plurality of large grooves and a plurality of small grooves are formed in the polishing surface, and each small groove is formed between every two adjacent large grooves; according to the grinding wheel, the thickness of the grinding surface is gradually reduced from the center of the grinding wheel base body to the edge direction, the chip removal efficiency in the earlier stage grinding process can be improved, the quality of machined objects is guaranteed, and the small grooves are formed in the grinding surface and located between the adjacent large grooves, so
