Sumitomo Releases New Turning Grades for Machining Stainless Steels
Sumitomo Electric Carbide Inc. recently released new AC6030M and AC6040M turning grades for machining stainless steels.
The AC6030M and AC6040M grades feature Sumitomo’s new AbsotechTM grade coating. Absotech coating improves wear resistance, adhesion resistance, and fracture resistance which extends tool life. The AC6030M possesses a new TiB2 surface layer that creates adhesion and chipping resistance. The AC6040M has an optimized Ti and Al composition resulting in improved flank and notch wear resistance.
The AC6030M and AC6040M grades have an expanded chipbreaker lineup highlighted by the newly developed EEM breaker, which provides improved chip control when roughing.
