SUMIBORON Coated SUMIB0R0N Hardened Steel BNC2010/BNC2020 Characteristics BNC2010 - High Precision 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 - General Purpose & High Efficiency 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. CBN-Substrate and Coating Structure of BNC2010 and BNC2020 BNC2010 Improved wear resistance Improved notch wear resistance Highly wear resistant CBN substrate Achieves excellent flank wear resistance thanks to a laminated structure of a TiCN-layer and special multi-layer coating.
