Cast Iron 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 High wear resistance !
- l
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
Interrupted cut is OK. (µm) Wear resistance is (Chipping 0,14mm) better than competitor’s. BNS800
Competitor’s CBN Competitors Fracture solid CBN interrupted cut.
