1. The manufacturing and application technology of domestic CBN grinding tools has entered a new stage of high level and rapid development, and has entered the mainstream market of automobile manufacturing. Some CBN abrasives are close to similar products abroad and can be substituted for imports.
2, application field expands unceasingly, already from the hard grinding tool industry metal material processing, to the bearing, automobile, machine tools, compressors and other industries of ordinary black metal materials processing, grinding way from general tool grinding, grinding, development to slow feed grinding, precision grinding, high speed grinding, the grinding of the CAM, the crankshaft grinding, a place of corundum abrasive streak.
3. High speed, high efficiency, high quality and low cost are its main features. The speed of use is generally 80~125m/s; Large residual coarse grinding is completed once; The working life of the workpiece can be increased by 20~30% due to the stress state on the surface of the grinding workpiece. The combined grinding cost can be reduced by more than 10%.
4. Domestic imported complete CBN grinding technology is growing rapidly.
5. Domestic high-speed CNC CBN special grinding machine has been developed successfully.
