Recommended CBN Grades and Chipbreakers Hardened Steel Grades BNC2010 / BNC2020 / BN1000 / BN2000 BNC2010: A grade for high-precision machining applicable for finishing requiring good surface roughness and dimensional accuracy. Provides further improved wear resistance thanks to a newly developed CBN substrate coated with a TiCN layer. Reduces flank wear and achieves excellent surface finish thanks to newly developed special stable multi-layered coating. BNC2020: A general-purpose grade applicable to general hardened steel machining. A newly developed tough CBN-substrate coated with a highly wear-resistant TiAlN layer. Achieves more stable machining and longer tool life by employing a highly adhesive layer for high chipping resistance. BN1000: For high speed machining. BN1000 provides the highest wear resistance of all uncoated SUMIBORON grades. Features improved fracture resistance while still placing a priority on wear resistance. BN2000: General purpose grade suitable for typical hardened steel machining applications. Provides a high degree of fracture and wear resistance.
