Sumitomo Electric's Binderless PCD won the 31st "Precision Engineering Society Technology Award"

Sumitomo Electric's practical development of the binderless PCD (Nano-polycrystalline diamond) won the "Precision Engineering Society Technology Award". The award is given to researchers who have demonstrated their creative performance in the field of precision engineering and related research and development of precision machines and production and processing technologies.

The newly developed ultra-high pressure technology and the first practically developed non-adhesive PCD in the world, directly combined with tiny particles of tens of nanometers, is a hardness and strength that exceeds the hardness of single crystal. An epoch-making hard material with excellent heat.

By analysing the structure and characteristics of the material, the excellent characteristics and the performance of the cutting tool are clarified, and the application range of the original difficult machining is increased, so that the superhard mold which can not be cut but can only be ground can be precision cut. Etc. These results have been well received and are hereby awarded.
