Solid CBN turning insertis the hardest known material eligible for the machining of ferrous materials and other super hard materials. CBNmaterials posses properties of high hardness, high resistance to corrosion and high thermal stability.Application ofCBN turning inserts:WorkPieceMaterialHardnessV(m/min)f(mm/rev)Ap(mm)GrayCastIronHB170~300500~15000.1~0.40.1~1.5AlloyedIronHB240~300150~3000.05~0.40.1~0.5NodularCastIron100~350200~4000.1~0.40.1~0.5P/MFe-basedHRC55-6550~1500.05~0.40.05~0.5HardenedSteelHRC55~6580~2000.05~0.20.05~0.2Heat-resistantAlloys110~16050~2000.05~0.20.05~0.2Advantage of our CBN Turning inserts :1.Hardness up to 8000 HV , is 80 ~ 120 times to hard alloy2. Coefficient of thermal conductivity is 700 W/mK, 1.5 ~ 9 times to hard alloy3. The friction coefficient is commonly 0.1 ~ 0.3 , It can significantly reduce the cutting force4. Thermal expansion coefficient of just 0.9? 10 ^-6 ~ 1.18? 10 ^-6. So the tool thermal deformation is small and the precision is high during processing .Pictures ofCBN turning inserts:about us:We are aprofessional manufacturer and innovator of premium quality tungsten carbide products.With 10+ years' special know-how and improvement, ourCBN turning insertsare widely used inautomotive industry such as cylinder/gear/,wheel,brakediscmachining.etc. withhighprecision,firmclamping and fast delivery.The products are exported to many countries and have gained ahigh reputation among customers for its stable quality and competitive price.Thanks for your support to Apple Carbide !AnnaTel:86-177 7336 5533
