Application of Halnn cbn insert hard turning slewing bearing
The main materials of wind power bearings will be 42CrMo, and the hardness after heat treating will be HRC47~55, and the machining site is the raceway. In the past, the manufacturers usually use ceramic insert for finishing process in the past, however the tool life will be low, and will affect the process efficiency. They are always search other cutting tools to improve the efficiency, and obtain higher surface roughness.
Halnn solutions for this application:
Halnn recommend BN-S200 solid cbn inserts for finish turning slewing bearings, the cutting speeds and feeds: Vc=60~250m/min, Fr=0.05~0.35mm/r,ap≤1mm, the application case as follows:
|
BN-S200 hard turning slewing bearings |
 |
Materials：42CrMo
Machining site:Raceway
Hardness：HRC47-55
Insert Model：BN-S200 RCMX090700
Cutting Speeds and Feeds：Vc=110m/min,Fr=0.45mm/r,ap=0.5mm
Process: Dry cutting |
Machining Effect: With Halnn BN-S200 solid cbn inserts hard turning slewing bearings, the cutting speed can be improved about 22%, and the tool life is improved 7 times which ensure the roughness Ra0.8 at the same time.
