Bearings, as one of the most important parts for supporting the rotation of machinery and equipment, are required high on the product quality. For example, wind power bearing, as one of the most important component for wind power machinery, it requires the end surface beating ranges within 0.005mm, and the race channel roughness needs to be within Ra0.3μm, and the thickness of the bearings ranges within 0.01mm.
Traditional cutting tools(carbide insert, ceramic cutters and coated carbide insert,ect) can’t meet all the requirements. Grinding process can meet the requirements on the dimension and roughness, but the efficiency is low, it also requires high on the operators. With the research of CBN Inserts and the appearance of Halnn BN-S200 solid cbn insert, high speed machining hardened steel part-bearings have been developed rapidly.
BN-S200 solid cbn insert use non-metal adhesive, improve the impact resistance, not only overcome the limitation on the cutting depth, but also avoid the failure risk caused by the failure of the brazing point. BN-S200 have obvious advantages on high speed machining bearings.
For example: High speed machining hardened steel part-bearing
Machining Workpiece: Wind Power Bearing
Machining Site: Raceway and End surface
Component materials:42CrMo(42CrMo4,42CD4)
Hardness: HRC47~55
Insert Model: BN-S200 RCMX090700
Cutting Speeds and Feeds:Vc=110m/min,Fr=0.45mm/r,ap=0.5mm
Machining Type: Dry Cutting
Comparing with ceramic cutters, the tool life of BN-S200 Solid CBN Insert is about 8 times of ceramic inserts, with 12% more cutting speed.

BN-S200 belong to solid cbn insert, both 2 sides can be used. And they can be used for heavy duty turning with both roughing and finishing process,and can obey heavy interrupt turning and not chip. With BN-S200 solid cbn insert high speed machining bearings, it can meet both the size precision requirements and roughness requirements, and reduce the production costs.
