Introduction and Selection of CBN Grinding Wheel

Grinding process is one of the oldest human processing means. With the development of the industry, especially the processing of hard metal, it is indispensable in the processing method. In the 1980s, the developed western countries CN machine tools and machining center get high speed development. The application of high-speed spindle and hard cutting tool make machine tools machining more expensive. But with the development of grinding technology, abrasive products have further been improved.

Innovation can improve the organizational structure and the new binder system can make abrasive products fundamentally improve the production efficiency. The invention of superhard abrasives CBN grinding wheel, not only can efficiently process hard steel (HRc 45-65), and increase the durability of grinding wheel. Especially Germany Krebs & Riedel Company as the representative, developed ceramic bond CBN grinding wheel in the mid-1980s, especially in the technical breakthrough on the sharp correction, and it is a revolution of the grinding abrasive products. The research and development success of ceramic bond CBN grinding wheel, in turn puts forward technical parameters on manufacturers of grinding machine. This grinding machine manufacturers and grinding wheel manufacturers can jointly develop CNC multi-axis grinding machines, which greatly improve the production efficiency,  reduce the production cost, and make the old process new splendor.

In the developed industrial countries, for large quantity and high precision grinding, the hardness of the machined parts HRc is above 45, and it needs to basically use ceramic CBN grinding wheel for grinding. CBN grinding wheel can be widely used in automobile main parts such as crankshaft, gear shaft and gear transmission, bearing and brake pads. Some precision mechanical parts used in machine tools are guide rail, lead screw and motor shaft grinding. Ceramic CBN grinding wheels are used for grinding processes of rolling roller wheels and in the aviation, aerospace, military industry and other areas are also widely used.

As a result of long production cycle of ceramic CBN grinding wheel, users must order in a planned way. Good manufacturers make grinding wheels according to users' production process and workpieces parameters. The selection of the abrasives, organizational slack, hard and soft grinding wheel and other production technical parameters should consider not only the technical parameters of grinding machine but the workpieces, so the application of CBN process for both buyers and sellers is high technology. Buyers must buy grinding wheel through professional channels, improving production efficiency and reducing production costs.
