Diamond grinding wheel is the special object for grinding hard alloy, glass, ceramic and gem.In recent years, with the rapid development of high-speed ultra-detailed grinding technique, higher requirements have been put forward for grinding wheel. Ceramic resin combined grinding wheel cannot satisfy the need of in-production. Metal combined grinding wheel has been widely used due to its obvious characteristics such as high joint strength, good formability and long service life.There are two kinds of examples of metal combined agent diamond grinding wheel according to production methods: sintering and electroplating.In order to give full play to the effect of super-hard abrasive, a new type of grinding wheel, namely single-layer low-temperature brazing super-hard abrasive wheel, was developed by low-temperature brazing in foreign countries from the early 1990s
