SUMIBORON Flank Wear Width (mm) Solid SUMIBORON for Cast Iron Machining BNS800 Cast Iron From finishing to roughing of cast iron and exotic alloys ■ General Features Enables great reductions in machining costs with a dedicated grade combining wear resistance and fracture resistance, and solid structure allowing the whole insert to be used as a cutting edge. Unlike conventional brazed type inserts, which are not L suitable for high speed cutting and roughing, this grade can beused even for high-speed finishing processes. Additionally, the RM type cutter is designed exclusively for Solid SUMIBORON and is suitable for high-speed rough milling. ■ Features ● Larger cutting depths 100% solid CBN structure where the whole cutting edge length can be used. ● Supports high-precision finishing Grade with excellent balance of wear resistance and fracture resistance. ● Achieves overall cost reductions BNS800 Dedicated Tool Holder L100 to L102 All corners of the insert can be utilised for greater economy.
