Why CBN tools for Cast Iron Machining?
Cast iron material being highly abrasive in nature with high content of carbon in form of graphite makes the hardmetal (Carbide, coated carbide) tools wear quite fast & CBN being most wear resistant material (exceeded in hardness only by diamond) gives excellent surface finish, increases the productivity by reduction of cycle time & tool change frequency/time, able to machine components with close tolerance consistently when applied to CI finishing applications.
