Sumitomo Electric Carbide is releasing the AC4010K and AC4015K turning grades for cast iron designed to promote longer, stable tool life. Having been treated for a smooth cutting edge, the system uses high-adhesion technology to improve peeling resistance. Additionally, crystal orientation control enables improved wear resistance during high-speed machining. The residual stress control technology of the series further contributes to wear resistance.
Recommended for the precision cutting of gray cast iron, the extra-thick coating of the AC4010K grade enables ultra-high-speed machining (vc = 2,300 sfm). Its surface treatment improves compressive stress and chipping resistance. Its range of applications includes cast iron brake discs and flywheels as well as ductile iron gear cases.
Recommended for the general purpose cutting of ductile cast iron, the high-adhesion and high-strength coating of the AC4015K grade provides longer and stable tool life.
Chipbreaker selection includes the EGU for low-rigidity work, the ENZ for general finishing, the EGZ for extra cutting edge strength and the EME for strong, sharp, high-feed cutting.
