Milling Cutter for Roughing, Finishing Cast Iron
Sumitomo Electric Carbide says its SumiMill Goalmill milling cutter accurately finishes cast iron.

New Generation Of Steel Turning Grades
Sumitomo’s next generation of P20 and P30 coated carbide turning grades include the AC820P, which is designed for general-purpose turning of steels and stainless steels and the AC830P, which is designed for interrupted cuts and roughing. The Super FF coating provides wear and breakage resistance while increasing tool life.


Coating For Dry Machining Of Al Alloys
Engineers from Sumitomo Electric Industries have developed a diamond-like carbon coating (DLC) for the dry machining of aluminum alloys and nonferrous applications. Previously, in the first stages of harsh-environment cutting, coatings would peel and lose their beneficial properties.

See The Tool's Value Instead Of Its Cost
This company is embracing high-performance tooling on its turning centers. The "sticker shock" is no reason not to do this. In one case, though, the shop found a way to limit the cost of the tool and increase productivity at the same time.
