BN-S200 Grade CNGN CBN Cutting Tool Hard Machining Bearing steel Wind turbine bearing
1. Halnn Tools Solid BN-S200 Grade CNGN CBN Cutting Tool Hard Machining Bearing steel Wind turbine bearing
When machining large scale bearings and high precision bearings, hard turning (turning instead of grinding) is a trend, the process efficiency is high and the cost is low. Traditional cutting tools carbide insert and ceramic cutters can’t satisfy their requirements.
With the widely used of the superhard cutting tools, turning instead of grinding already become a reality. As the leader of supehard cutting tools in China, Halnn Tools has special cutting tools for hard turning bearings, not only realize stable cutting performance, ensure the roughness, but also help the bearings industry reduce the total costs.

5.Application Case of CBN Cutting Tool Machining Bearing
BN-S200 Grade CNGN CBN Cutting Tool Hard Machining Bearing steel Wind turbine bearing
This process required high on the impact resistance of the cutting tools, Halnn recommend solid cbn inserts, common insert models: CNMN
Compared with traditional cutting tools, the processing efficiency is improved, and the roughness can arrive Ra0.8.
Application Case:
Machining Site: Raceway and End Surface
Materials: 42CrMo4
Hardness: HRC47~55
Insert Model: BN-S200 CNMN
Cutting Data: Vc = 110m/min, Fr=0.45mm/r, ap=0.5mm
Processing Type: Dry Cutting
Compared with the ceramic cutters:
| Insert Materials | Cutting Speed (m/min) | Tool Life | Roughness |
| Halnn BN-S200 | 110 | 8 | Ra0.8 |
| Ceramic Cutters | 90 | 1 | Ra1.6 |
