Five insert edge preparations for different hard metal turning applications when using Sumitomo Electric Hardmetal’s latest developments, BNC2010 and BNC2020 cubic boron nitride (CBN) inserts, enable specific process situations and problems to be overcome giving higher stability and greater operational consistency.

 

BNC 2010 has been developed to provide high precision contouring and machining with cutting speeds between 80 and 300 m/min. It is based on a high wear resistant CBN sub platform with multi-layers of TiCN that improves resistance to notch and flank wear, enables high orders of surface finish to be obtained and is especially efficient at removing carburised layers.

BNC2020 is more suitable for general purpose turning and interrupted surfaces at speeds between 60 and 200 m/min. It has a tough CBN base with a specialist adhesion layer to provide higher wear and chipping resistance through the TiAlN coating.
