Project Description

Newly developed high adhesion technology, crystal orientation control technology, and residual stress control technology for longer and stable tool life with various cast irons–from gray cast iron and ordinary cast iron (FC) to high-strength ductile cast iron (FCD).


Recommended grade for gray cast iron. Ultra-thick coating allows for ultra-high-speed machining (vc = 700m/min).


Recommended grade for ductile cast iron. High-adhesion, high-strength coating provides longer and stable tool life.
