Development and Release of New Coated Carbide Grade “ACECOAT AC820P” for Steel Turning

(1)

Enhanced wear resistance; improved chipping resistance on edges

The new “ACECOAT AC820P” incorporates Sumitomo Electric Hardmetal’s original chemical vapor deposition (CVD) coating, “SUPER FF COAT.” By obtaining the maximum film thickness, at least twice as much wear resistance as that of conventional grades is provided. The coating technology for controlling the film thickness of cutting edges has greatly improved edge strength, achieving at least 1.5-times the chipping resistance compared to existing grades and providing longer life and more stable machining.

(2)

High efficiency machining at least 1.5-times faster than ever

Sumitomo Electric Hardmetal has developed a “GE-type chip breaker” that can significantly reduce damage to the rake face, which becomes primary damage in high-speed or fast-feed high efficiency machining. The combination of the “ACECOAT AC820P” and the “GE-type chip breaker” enables high efficiency machining that is at least 1.5-times that of conventional grades.

Although priced the same as the Company’s conventional products, “ACECOAT AC820P” is expected to substantially reduce machining costs, since its long service life reduces tool consumption and the frequency of tool change, while its high efficiency shortens machining time.
