Sumitomo Electric Wins JSPE Technology Award 2011

Sumitomo Electric Industries, Ltd. received a Technology Award from the Japan Society for Precision Engineering for its achievement in developing binderless nano-polycrystalline diamond (PCD) for commercialization. This award is granted to researchers for creative performance in research and development of precision equipment or manufacturing technologies.

A newly developed ultra high pressure technology was applied to develop the world’s first practical binderless nano-PCD. Made up of directly and strongly bound fine particles as small as tens of nanometers, the nano-PCD outperforms single-crystal diamond in hardness and toughness. It is a highly heat-resistant, epoch-making hard material.

The award recognizes the Company’s efforts to reveal these excellent features and performance for use in cutting tools through analyses of the material’s structure and characteristics, proving its usability for a wide range of precision machining applications, such as precision cutting of carbide dies, which are machined by grinding instead of cutting.
