AC4000K series - Coating Grades for Cast Iron
New grade series covering cast iron processing completely!
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).
Our first recommended grade for gray cast iron. Ultra-thick coating allows for ultra-high speed machining (vc = 700m/min).
Our first recommended grade for ductile cast iron. High-adhesion, high-strength coating provides longer and stable tool life.
