SUMIBORON Series Grades Coated SUMIBORON Series CBN Characteristic Values Work Materials Grades BNC2010 Binder TiCN CBN Content (%) Grain Size (μm) Hardness HV (GPa) 50 to 55 2 30 to 32 TRS (GPa) 1.10 to 1.20 Main Coating Components Coating Thickness (μm) TiCN multi- 1.5 Characteristics Improves the wear resistance of coating and substrate and stably achieves excellent A layered Grades surface roughness. Provides long tool life in general and high-efficiency TiAlN multi- BNC2020 TiN 70 to 75 5 34 to 36 1.20 to 1.30 layered 1.5 cutting thanks to tough substrate coated with a highly wear-resistant and highly adhesive layer. Suited for finishing when there is a Carbide Coated BNC300 TiN 60 to 65 1 33 to 35 1.15 to 1.25 TiAIN 1 combination of continuous and interrupted cutting. Highly wear resistant coating makes this BNC100 TiN 40 to 45 1 29 to 32 1.05 to 1.15 TiAIN/TiCN 2 grade suited for high speed finishing. Cermet Stable, high precision finishing of hardened BNC160 TiN 60 to 65 3 31 to 33 1.10 to 1.20 TiAIN/TiCN 2 steel. Ceramic Tough substrate with high wear resistant BNC200 TiN 65 to 70 4 33 to 35 1.15 to 1.25 TiAIN 2 coating provide longer tool life. H Hardened Steel Ultimate wear and fracture resistance. BN1000 TiCN 40 to 45 1 27 to 31 0.90 to 1.00 ̶ ̶ Suited to high-speed cutting. Carbide A general purpose grade for hardened steel BN2000 TiN 50 to 55 2 31 to 34 1.05 to 1.15 ̶ ̶ that provides a high degree of fracture and wear resistance. Crater resistant grade, suitable for high BNX20 TiN 55 to 60 3 31 to 33 0.95 to 1.10 ̶ ̶ efficiency cutting under high temperature Layer CBN conditions. High cutting edge strength, suited to heavy BN350 TiN 60 to 65 1 33 to 35 1.20 to 1.30 ̶ ̶ interrupted cutting. PCD Optimum wear resistance. Suited to BNX10 TiCN 40 to 45 3 27 to 31 0.80 to 0.90 ̶ ̶ continuous, high-speed cutting. Excellent fracture resistance during BNX25 TiN 65 to 70 4 29 to 31 1.00 to 1.10 ̶ ̶ high speed cutting. Suited to high speed interrupted cutting of hardened steel. Co Maintains optimum cutting edge sharpness. BN7500 90 to 95 1 41 to 44 1.40 to 1.50 ̶ ̶ Compound Suited for finishing of sintered alloy. Sintered alloy Co Improved wear and fracture resistance in BN7000 90 to 95 2 41 to 44 1.30 to 1.40 ̶ ̶ Compound rough cutting of sintered components. 100% solid CBN structure with good BNS800 Al Alloy 85 to 90 8 39 to 42 0.95 to 1.10 ̶ ̶ thermal impact resistance. Co Improved wear and fracture resistance in BN7000 90 to 95 2 41 to 44 1.30 to 1.40 ̶ ̶ Compound rough cutting of cast iron and exotic alloy. K Cast Iron Optimized for cast iron cutting. BN500 TiC 65 to 70 6 32 to 34 1.00 to 1.10 ̶ ̶ Maintains good wear and fracture resistance. Substrate with excellent wear resistance BNC500 TiC 60 to 65 4 32 to 34 1.00 to 1.10 TiAIN 2 and coating makes this grade suited for （For Ductile Cast Iron） hard-to-cut cast iron.
