Sumitomo Electric Won Nikkan Kogyo Shimbun’s Best 10 New Products Awards

Our nano-polycrystalline diamond tool won the main award in the 2012 Best 10 New Products Awards sponsored by The Nikkan Kogyo Shimbun (Business and Technology Daily News). These awards are given to products that are revolutionary and original and that contribute to the production industry, selected by the newspaper from among the products released or developed in the year.

Sumitomo Electric has developed Sumidia Binderless, a nano-polycrystalline diamond that excels in hardness and solves the problem of cleavage compared with single-crystal diamond. Using this material as a cutting edge, Sumitomo Electric has developed fine-processing ball end mills and turning tools for processing hard vulnerable materials. A.L.M.T. Corp. has developed cutting tools for the ultrafine processing of products such as dies for optical components.
