For light to medium interrupted machining | CBN for machining hardened material
High performance, low cost CBN
Recommended for semi-interrupted cuts
Versatile CBN designed for machining hardened materials at 55 HRC or above with light to medium interruptions
Product video
Features
- CBN with a special TiCN binder achieves a combination of wear resistance and fracture resistance
- Stable performance through light to medium interrupted machining
- B6K (coated CBN):
A special hard TiCN layer prevents a chemical reaction between the CBN and the iron in the work piece during material removal
B36 (uncoated CBN):
Ideal for machining the hardened material layer
Tooling application
Light to medium interrupted machining of hardened materials of HRC55 or above

Performance comparison by edge preparation

- As the edge preparation increases the tool pressure on the insert increases.
- [ Cutting conditions ]
- SCM415(HRC63-65) vc=200m/min f=0.1mm/rev ap=0.2mm DRY
- [ Insert ]
- TNGA160408

- There is a direct correlation between an increase in the edge preparation and improvement of insert fracture resistance.
