Superhard abrasive brazed grinding wheel is an important tool to achieve high efficiency grinding. Compared with traditional grinding wheel, the brazed grinding wheel not only has high bonding strength, but also has the advantages of large chip holding space, not easy to block and full use of abrasive. In order to improve the overall performance of the grinding wheel for high efficiency grinding, the researches about the research and development of the active solder, the topography and optimization of the grinding wheel, the research on the brazing technology, the structural design of the new brazing wheel and the accuracy of the brazing wheel at home and abroad were summarized.The problems of precision and cost of the superhard abrasive brazed wheel are the bottleneck for its application and development in high efficiency grinding. It is of great significance to study and solve the problems of precision and manufacturing cost of the superhard abrasive brazed grinding wheel for promoting the development of efficient grinding technology.
