Insert Grades Insert Grades CBN (Cubic Boron Nitride) Features of CBN CBN CBN (Cubic Boron Nitride) is second only to diamond in hardness, and is a synthetically produced material with high thermal conductivity. Features Superior wear resistance when machining hard materials Suitable for high speed machining of hard materials, sintered steel and cast iron High thermal conductivity provides stable machining Classification Symbol Color Ave. grain size ( jm) Hardness of Substrate (GPa) Transverse Strength (MPa) Advantages and Applications KBN510 Black 2 28 1,000 Excellent wear resistance and crack resistance, non-coated CBN Application: Finishing and continuous machining of hardened die steel KBN525 Black 1 and under 25 1,250 Application: General purpose for hardened steel H 1 Hard Materials I KBN05M (MEGACOAT) Blackish red 0.5-1.5 27 1,000 Heat-resistant MEGACOAT on highly heat-resistant CBN substrate Application: High speed finishing of hardened steel KBN10M (MEGACOAT) Blackish red 2 28 1,000 Application: High speed finishing of hardened die steel KBN25M (MEGACOAT) Blackish red 1 and under 25 1,250 Heat-resistant MEGACOAT on micro-grain CBN with heat-resistant binder phase Application: Stable machining of hardened steel at high cutting speeds KBN30M (MEGACOAT) Blackish red 1-4 s0 1 50 Application: Stable machining of hardened steel for continuous to interrupted machining Sintered Steel KBN65B Black 2 s2 1,150 Application: Stable machining of sintered steel (ferrous sintered alloy) at low speed KBN570 Black 2-4 s4 1 50 High CBN content ratio Application: Machining of sintered steel (preventing burr formation) KBN65M (MEGACOAT) Blackish red 2 s2 1,150 Heat-resistant MEGACOAT on CBN with heat-resistant binder phase Application: Stable machining of sintered steel (ferrous sintered alloys) KBN70M (MEGACOAT) Blackish red 2-4 s4 1 50 Heat-resistant MEGACOAT on CBN rich substrate Application: Stable machining of sintered steel (ferrous sintered alloys) pm KBN475 Black 2 s9 1,400 Excellent wear resistance due to high CBN content and special binder Application: High speed machining of gray cast iron KBN60M (MEGACOAT) Blackish red 0.5-6 ss 1,250 Heat-resistant MEGACOAT on CBN rich substrate with hard binder phase Application: High speed finishing of gray cast iron Cast Iron KBN900 (TiN COAT) Gold 9 s1 6s0 TiN coated solid CBN Application: Heavy duty, interrupted machining and finishing of hardened steel, hardened roll steel and cast iron For KBN35M , see page 3A18 MEGACOAT CBN Properties of PVD Coating MEGACOAT TiN 400 600 800 1,000 1.200 Oxidation temperature (°C) iiiii Oxidation resistance Application Map Hard Materials KBN05M -t- KBN10M KBN25M I KB N30M KBN35M Advantages of MEGACOAT Longer tool life and high speed machining due to superior heat resistance and hardness Stability improvement through prevention of crater wear (oxidation, diffusional wear) High thermal stability and surface smoothness provide excellent surface finish Sintered Steel Finishing Medium Roughing Continuous Light Interruption Interruption Heavy interruption 0 0 8 0 Cast Iron KBN70M k KBN570 KBN65B S2ZT KBN475 KBN60M KBN900 Finishing Medium Roughing Continuous Light Interruption Interruption 3 Finishing Medium Roughing Continuous Light Interruption Interruption O High A16
