Coated SUMIBORON H Hardened Steel Characteristics New Coated SUMIBORON Series achieving - higher speed - higher efficiency and - higher precision - General Features Using a high heat resistant and tough CBN substrate coupled with a special ceramic coating, this series caters to a wide va- riety of applications with improved precision and longer tool life BNC2010 BNC2020 as compared to conventional CBN. There is a comprehensive lineup of economical and easy-to- use insert selection, such as the cost effective double-sided, multi-cornered, one-use type inserts. BNC2010 and BNC2020 are the latest additions to the Coated SUMIBORON series, to provide even better stability and longer tool life for hardened steel machining. BNC100 BNC160 BNC200 BNC300 BNC500 - Characteristics Easy Edge Management Strong Brazing Numbering of cutting edges. Utilizing a new brazing method with improved strength. Double sided, Multi-cornered One-use Insert More cost effective than conven- tional one-use inserts. Special Ceramic Coating and Newly Developed CBN Substrate Provides longer tool life. - Cutting Performance - Cutting Edge Management Conditions Recommended Cutting Speed (m/min) Before usage Application General Purpos (Continuous to Light interrupted Rz = above 3,2) SUMI BORON After usage Finishing Heavy Hardened Steel Interrupted High Precision (Rz = 1,6 to 3,2) The edge numbers are still visible after machining, which makes the management High Efficiency of used cutting edges easy. (Carburized layer removal) BNC2010 and BNC2020 are coated in gold, which makes it easy to distinguish used edges. Cast Iron Ductile Cast Iron L10
