Best quality Square SNGN090408 PCBN Cutting Tool full form Hard Turning Hardened Steel Wind turbine bearing

1. Halnn Tools PCBN Cutting Tool full form Hard Turning Hardened Steel Wind turbine bearing

The hardness of the slewing bearing after heat treatment is generally above HRC45, and the channel portion is generally HRC55-62, so it is difficult to process during processing. Halnn Tools has developed the BN-S200 grade and BN-S20 grades of cubic boron nitride tools. Both materials are made of non-metal (ceramic) as a binder to ensure high hardness and wear resistance. At the same time, the impact toughness is improved, in which the BN-S200 grade belongs to the finishing process, and the BN-S20 grade can be roughing and finishing.
