The characteristics of CBN abrasive and application technology development

CBN grinding tool manufacturing and application technology development has the following characteristics:

1, domestic CBN grinding tool manufacture and application of the technology into the high level and a new stage of rapid development, and has set up a enters the mainstream market of auto manufacturing. Part of the CBN abrasive performance close to the level of similar foreign products, can replace imported.

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 is its main feature. Using the speed reached 80 ~ 125 m/s; A complete big margin thick fine grinding; In compressive stress state caused by grinding the workpiece surface to improve the service life of the workpiece by 20 ~ 30%; Integrated grinding cost can reduce more than 10%.

4 domestic and imported complete set of CBN grinding technology showed the trend of rapid growth.

5, domestic high speed numerical control CBN grinding machine has been developed.
