Heavy Interrupt Cutting 42CrMo4 Bearing PCBN Inserts BN - H21 CNGA120404-4S

Bearing is the key basic component of machinery manufacturing industry and the core component of wind power generator. Due to the harsh environment and inconvenient installation and maintenance, the requirements for the quality and service life of the wind power bearing parts are more stringent.

At the beginning of the wind power bearing, since the hardness of the bearings is subjected to heat treatment after the rough machining, the hardness is high and difficult to be processed, and the grinding is commonly used as the final process step, but with the development of modern cutter industry, the tool material can be turned on the ground for grinding, and the boron nitride blade is developed. Instead of grinding processing, not only improve the processing efficiency, but also reduce the processing cost.
