BNS800Solid SUMIBORON for Cast Iron Machining

From Finishing to Roughing of Cast lron and Exotic Alloys!

• General Features New solid structure CBN insert. As all the edges can be used, total machining cost will be lower, compared to conventional CBN inserts. Biggest demand for this insert will be in Cast Iron machining. As conventional brazed CBN inserts are not suitable for high speed cutting and roughing, BNS800 can be used even for high speed finishing processes with many times the tool life of ceramic inserts. Additionally, RM type cutter is developed exclusively for Solid SUMIBORON and is suitable for high-speed rough milling.
• Characteristics Larger Cutting Depths

100% solid CBN structure where the whole edge can be use.

• High Precision Machining Excellent balance of wear resistance and toughness. Refer to pages L98 to L99
