Others Non-coated cBN DB1000 O Features Non-coated cBN with the highest wear resistance at high speed Excellent tool life in continuous to light interrupted cutting Improved fracture resistance along with high wear resistance - Higher thermal resistance and hardness due to pure TiCN ceramic binder Non-coated cBN DB2000 O Features Universal grade for overall machining of heat-treated - Stable tool life in continuous to low/medium interrupted cutting Both fracture resistance and wear resistance acquired with the use of pure ceramic binder Stable surface roughness O New technology of high purity ceramic binding materials Conventional grade DB2000 dramatically minimizes impurities with the use of high purity ceramic binding materials and enhances thermal resistance and toughness. Impurities included in conventional grade's ceramic binder caused inferior thermal resistance and hardness of sintered compounds, which led to crack (fracture) and wear O Application range Interrupted cutting of heat-treated steel a 300 D U> C E 200 i1 I = o 100 = > o DB1000 - -J D 32000 Degree of interruption Continuous Genera cutting cutting 8 Medium interrupted cutting I min-Overload on-max cutting edge O Recommended cutting condition (DB1000) O Recommended cutting condition (DB2000) Grades & Chip Breakers 50 Cutting speed Cutting speed vc (m/min) vc (m/min) Feed Feed fn (mm/rev) 0.03 0.15 fn (mm/rev) Depth of cut Depth of cut ap (mm) ap (mm)
