Materials for aircraft parts are becoming increasingly difficult to cut, such as heat-resistant alloys, titanium alloys, aluminum alloys, CFRP and other composites. Sumitomo Electric provides products and technical services that realise highly efficient, high-precision cutting of these difficult-to-cut materials by utilising the powder metallurgy and ultra-high pressure technologies it has developed over the years.More Detail
EV Traction System
As an important step towards achieving 'carbon neutrality', a common global challenge, the drive systems of vehicles are expected to become increasingly electrically powered. Using the technology we have developed over many years in the development of tools for machining automotive components, we also provide optimal tools and services based on customer needs for EV drive system components.More Detail

Reference to grade information (Turning grades).
The following is a combination of 'Workpiece x Wear resistance - Chip resistance' for each material type.
Reference for chipbreakers and negative types classified by cutting application. For each breaker symbol, the following information is presented: features, applicable work material, shape photo, cross-sectional profile, cross-sectional profile model number, relief angle and stock shape.
Cemented Carbide "IGETALLOY"
"Igetalloy", a cemented carbide, is an alloy that combines hardness second only to diamond with the toughness of steel, and has a 70-year track record and a wide range of grades to suit different applications.
CBN "SUMIBORON"/ PCD "SUMIDIA"
"Sumiboron" is a material that main component CBN (cubic boron nitride) is sintered under ultra-high pressure and temperature with a special ceramic binder.
"Sumidia" is a material that sintered diamonds are made from ultra-fine diamond particles sintered to a high density.
