High-speed grinding wheel for glass processing Technical Field The utility model relates to the technical field of glass processing, in particular to a high-speed grinding wheel for glass processing. Background In the field of glass deep processing, in particular to the grinding processing of high-precision electronic glass and optical glass, the performance of a high-speed grinding wheel directly determines the processing efficiency and the quality of a finished product. The traditional grinding wheel is made of single material (such as common alumina or silicon carbide), and has certain cutting capability, but the grinding wheel is easy to crack or burn on the surface of glass due to great brittleness and uneven heat conduction of the material when the grinding wheel is operated at high speed (such as more than 12 m/min). In addition, the connection strength of the grinding wheel and the mounting seat is insufficient, structural fatigue is easily caused by long-term high-speed rotation, and the service life is shortened. In the prior art, the cutting fluid circulation system is usually cooled by external spraying, but the inside of the grinding wheel is lack of a directional guide structure, so that the cutting fluid is difficult to fully permeate into a grinding contact area, the cooling efficiency is low, the local temperature rise of glass is obvious, and microcracks or edge breakage is easy to generate. Part of grinding wheels try to add an internal runner, but the problems of chip backflow blockage, runner abrasion and the like are not solved, and the risk of unbalance of the grinding wheels is increased. On the other hand, although the rigidity connection design of the grinding wheel and the base improves the stability, stress concentration is easy to generate under high-speed thermal load due to the difference of thermal expansion coefficients of materials, and the connection part is cracked, so that the high-speed grinding wheel for glass processing is needed at present.
