A SiC whisker-reinforced Al2O3 ceramic that is very effective at machining nickel- and cobalt-based super alloys, alloyed cast iron, and hardened steels at metal removal rates up to 10 times higher than carbide. Whisker ceramic inserts derive their application strength in machining from the composition of the ceramic base matrix with the finely distributed silicon carbide crystals embedded in it - the whiskers: hardness, fracture toughness, thermal conductivity and edge stability are increased and allow. Kyocera's ceramic inserts are capable of running at high speeds, thus reducing expensive machining times. Hard turning of 38Rc to 64Rc carbon and alloy steels, or rough to finish turning of cast irons is recommended ceramic inserts. 3x longer tool life than CBN when machining hardened steel part of 54 HRC. Produced oduced from from Recycled Recy l d paper Aug. In fact, the high-speed capabilities of ceramics result in metal removal rates that are four to.
