Width of Flank Wear K Cast Iron Uncoated SUMIBORON BNS800 Solid CBN grade for high speed rough and finish machining of cast iron - General Solid CBN grade with high content CBN and special binder phase provide high fracture toughness and high thermal conductivity. Solid inserts for roughing with high depth of cut and also for finishing of cast iron and alloyed cast iron at wet and dry conditions. - Advantages l High wear resistance ! High CBN-content and special binder phase provide a excellent wear resistance and a tight dimensional control in finish machining. l High edge stability ! High thermal conductivity of BNS800 and high edge stability provide a long tool life at wet and dry machining. - Performance Continuous Cutting Interrupted Cutting (µm) Wbeetaterrrethsaisntacnocmepiestitor’s.Competitor’s CBN Interrupted cut is OK.(Chipping 0,14mm)BNS800 Competitors Fracture solid CBN interrupted cut.
