Mitsubishi Materials has extended its renowned MC5000 series of turning inserts for cast iron with the launch of several new geometries for the MC5005 and MC5015 CVD coated grades. MC5005 introduces an innovative new ultrathick Al2O3 layer that is twice the thickness of conventional coatings. This combines with a TiCN nano-texture layer that is bound by Mitsubishi’s patented ‘Tough Grip Technology’ to outperform conventional carbide and ceramic grades, when conducting continuous cutting of grey cast iron. This ultra-thick layer prevents the coating from peeling and eliminates edge chipping that is a common occurrence with competitor grades. Complementing MC5005, the MC5015 series is composed of the same substrate and coating layer technology as the MC5005, but has been developed for interrupted machining applications. With a thicker TiCN layer than MC5005, the MC5015 series has an ideal distribution of hardness and toughness that provides extreme plastic deformation resistance nearer the surface whilst delivering overall toughness to prevent insert breakage under heavy loads during interrupted machining.
