 Coated SUMIBORON for Hardened Steel Machining  BNC2010/BNC2020 First choice for Longer Tool Life and Cost Reduction ■ General Features Provides improved machining accuracy and longer tool life as compared to conventional Coated SUMIBORON by combining newly developed CBN substrate and ceramic coating. Exhibits excellent performance in high-precision and general cutting of hardened steel and enables reductions in machining costs. BNC2020 ■ Characteristics ● BNC2010 ・For high-precision nishing requiring good surface roughness and dimensional accuracy. Ideal for high-precision machining thanks to excellent wear resistance. ・Further maintains excellent surface roughness. Consistently excellent surface roughness thanks to coating with high notch wear resistance and CBN substrate. ● BNC2020 ・General-purpose grade suitable for typical hardened steel machining applications. Achieves further stability in machining of a wide range of hardened steel components. ・Achieves long tool life thanks to highly wear-resistant, highly adhesive coating and tough CBN substrate. Achieves stable and long tool life even in high-efficiency and interrupted machining. ■ CBN Substrate and Coating Structure of BNC2010 and BNC2020 BNC2010 BNC2020 TiN Coating TiN Coating TiCN Coating Improved Wear Resistance Special Multi-layered Coating TiCN Coating TiAlN Coating Improved Wear Resistance Special Multi-layered Reduced Boundary Wear Coating TiCN Coating Special Multi-layered Highly Adhesive Layer Improved Adhesion Coating High wear resistant Tough CBN substrate CBN Substrate L Achieving excellent notch wear resistance with a coating structure of Achieving even better stability with a TiAlN layer TiCN layers and special multi-layered coatings. and a highly adhesive coating layer.
