SUMIBORON C°ated SUM BORON h Hardened Steel BNC100 Coated Sumiboron premium grade for high speed machining of hardened steels I General Features Our copper coloured Sumiboron grade BNC 100 resists premature plastic deformation of the cutting edge by withstanding the high temperatures that occur when machining hardened steels. This new grade features a heat resistant CBN substrate and a special TiCN based ceramic coating to enhance surface finish across a broad range of finishing applications at elevated cutting speeds. Ideal for higher speed machining and suitable for continuous or light interrupted cuts BNC100 delivers reliable performance and excellent tool life m I Advantages High speed machining Suitable for continuous to light interrupted high speed cutting with Vc = 150 300 m/min. Extended tool life Wear resistant ceramic coating and tough CBN substrate considerably extends tool life. Excellent surface finish A consistent surface finish to values less than 6,3 Rz is easily achieved on both continuous and light interrupted cut applications.
