CB70

● Best suitable for high speed finish machining of cast iron.             
●Realizing the high efficiency processing of sintered alloy.
●Corresponding to various difficult processing materials, taking into account cast iron and hardened steel, better on heat-resistance.

Cast Iron/Hardened steel

Auto brake disc, Brake Drum, Cylinder blocks of car engines, Cylinder liner, Gear，Bearing.

CB90

●Common CBN material for all machining of Hardened steel.                   
● Updated material with wear-resistance and anti-breakage.        
● From continuous cutting to light -middle-interrupted cutting，the stability and sharp are improved, the surface roughness are also very stable.
