2016年1月19日 · • Sumitomo’s new BNC2020 grade contains CBN particles that provide superb chipping resistance, stable performance and long tool life. BNC2020 grade specializes in high efficiency cutting of interpreted hardened steel material.

Combination of a tough CBN substrate and a thick coating that has a balance of wear resistance and toughness, to achieve stable machining in a wide range of applications. Excellent wear resistant CBN substrate and coating layer, for high-precision machining that requires surface roughness and surface finish accuracy.

Gold-colored coating for improved visibility of used corners. Optimising the particle size distribution of the CBN particles has resulted in improved chipping resistance and longer life while maintaining wear resistance during grey cast iron machining. …
