H Hardened Steel Coated / Uncoated SUMIBORON BNC300 / BN350 The ultimate grades BNC300 and BN350 in interrupted machining of hardened steel I General Features BNC300 CBN substrate that emphasizes on toughness coupled with a highly wear resistant TiAIN based coating layer that has improved adhesion strength. With a good balance of fracture and wear resistance, stable and longer tool life can be achieve in interrupted cut or in a mixture of continuous and interrupted cutting. BN350 SUMIBORON series highest fracture resistance and toughest CBN. Reliable grade for achieving stable tool life in heavy interrupted cutting conditions. Characteristics BNC300 Stable and long tool life in interrupted cutting Achieving stable and long tool life in heavy interrupted cutting, with superior fracture resistance. Superior dimensional precision Good adhesion strength, TiAIN based, high wear resistance coating. Achieving superior dimensional precision even in interrupted cutting. Suitable for different types of workpieces Achieving significantly longer tool life even on workpieces that have a mixture of continuous and interrupted cutting. BN350 Stable and long tool life in interrupted cutting Stable and long tool life with superior fracture resistance, that prevents fractures which commonly occurs during interrupted cutting.
