COATED CBN SERIES
FEATURES
With the expansion of BC8020, Mitsubishi can offer 3 coated CBN grades for machining of hardened steels. These 3 coated CBN grades cover a wide range of applications.
To achieve longer tool life, Mitsubishi uses a unique "Particle-activated Sintering Method", combined with increased cutting edge strength. With high crater wear resistance CBN grades and a wear resistant ceramic coatings, longer tool life and improved machine efficiency are obtained.
| Grade | Grade Features and Application | Main Component | Coating Layer |
|---|---|---|---|
  |
High effi ciency coated CBN Increased cutting edge strength and high crater wear resistant CBN grade in combination with a highly wear resistant TiAlN coating, results in longer tool life and improved machining efficiency under heavy duty or interrupting cutting. |

Coated CBN for High Speed Continuous Cutting MBC010 makes the best use of a special ceramic binder structure, actualizing high wear resistance. High wear resistance enables continuous machining at high speeds of over 300m/min. |
CBN (Micro Grain) TiN Al2O3 |
TiN |
 |
Coated CBN for general cutting (First recommendation) Uses a CBN substrate that has high cutting edge rigidity. The TiAlN based coating delivers superb wear resistance. CBN grade first recommendation. |
