1. Diamond tool manufacturers introduced that the manufacturing and application technology of domestic CBN abrasive tools has entered a new stage of high level and rapid development, and has entered the mainstream market of automobile manufacturing. The performance of some CBN abrasive tools is close to the level of similar foreign products and can replace imports.
2. The application field has been expanding. The processing of difficult-to-grind metal materials in the tool industry has been extended to the processing of ordinary ferrous metal materials in industries such as bearings, automobiles, machine tools, and compressors. The grinding methods have also changed from general tool grinding and internal grinding. Circular grinding has developed into slow feed grinding, high-precision grinding, high-speed grinding, cam grinding, crankshaft grinding, and it has the potential to replace corundum grinding tools.
3. High speed, high efficiency, high quality and low cost are its main features. The use speed generally reaches 80~125m/s; the large margin rough and fine grinding can be completed at one time; because the surface of the ground workpiece is in a state of compressive stress, the service life of the workpiece can be increased by 20~30%; the comprehensive grinding cost can be reduced by more than 10%.
4. The domestic imported complete set of CBN grinding technology is showing rapid growth.
5. The diamond tool manufacturer introduced the domestic high-speed CNC CBN special grinder that has been successfully developed.
