The ceramic bond diamond grinding wheel has high strength, good heat resistance, sharp cutting, high grinding efficiency, no heat generation and clogging during grinding, and small thermal expansion to control the machining accuracy. Compared with the resin bond grinding wheel, he solves the problem that the resin diamond grinding wheel has a low life, the grinding efficiency is low, and the grinding tool itself is easily denatured during the grinding process. It is based on the above advantages of the ceramic wheel binder diamond grinding wheel. Its appearance is immediately widely used in the developed countries of Europe and America in wafers (semiconductor wafers and solar wafers), diamond composite sheets, diamond polycrystals, diamond tools, cubic nitriding. Boron, tungsten steel (hard alloy), new engineering structural ceramics, gemstones, crystals, rare earth materials (magnetic materials) and other high-hard brittle materials, and achieved good economic benefits.
Early ceramic bond diamond wheels for grinding PCD tools did not have uniform specifications and models. Around 2008, the domestic manufacturers of ceramic bond diamond grinding wheels for grinding PCD tools began to appear in China. The pioneers of a number of renewed resin bond diamond grinding wheels have also been continually exploring the ceramic bond diamond grinding wheel to process PCD tools. 6A2 has gradually become a regular model of grinding PCD tool grinding wheels, the diameter is 150, 125, 100 conventional specifications. At present, many domestic users call the ceramic bond diamond grinding wheel for PCD to be 6A2 ceramic diamond grinding wheel, cup type ceramic diamond grinding wheel and grinding PCD/PCBN tool diamond grinding wheel. With the development of the mechanical manufacturing industry, more and more people call it a ceramic diamond knife grinding wheel. The domestic production process of ceramic bond diamond grinding wheels is also maturing.
