Bearing parts case - CBN tooling for hardened steel bearing inner ring



In order to improve the wear resistance of mechanical components and increase their service life, many structural steel components are often quenched and processed. However, the high strength and hardness of quenched components and their poor plasticity can cause problems for turning.



The performance of tools is important to the efficiency and accuracy of turning operations. Improving the performance of tools has been one of the challenges continuously explored and discussed in the machinery and equipment manufacturing industry.


The CBN material for high-speed finishing, which has even better wear resistance, continues to improve its chipping resistance alongside its wear resistance.
