H Coated / Uncoated SUMIBORON
Hardened Steel BNC300 / BN350
The ultimate grades BNC300 and BN350 in interrupted machining of hardened steel
General Features
BNC300 BNC300
l
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.
l BN350
SUMIBORON series highest fracture resistance and toughest CBN.
BN350 Reliable grade for achieving stable tool life in heavy interrupted
cutting conditions.
Characteristics
BNC300 l Stable and long tool life in interrupted cutting
Achieving stable and long tool life in heavy interrupted cutting, with superior fracture resistance. l Superior dimensional precision Good adhesion strength, TiAIN based, high wear resistance coating. Achieving superior dimensional precision even in interrupted cutting. l Suitable for different types of workpieces Achieving significantly longer tool life even on workpieces that have a mixture of continuous and interrupted cutting.
BN350 l 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.
