■ General Features

SUMIDIA is a polycrystalline diamond material developed by using our

proprietary technologies.

SUMIDIA is available in 4 grades (DA90, DA150, DA2200 and DA1000), each

having different characteristics depending on the size of the diamond grains

and the combination of binder materials.

In addition, a new grade (NPD10) made by nano-level diamond grains without

binder material with direct conversion sintering has been newly added to our

product line.

SUMIDIA can be used for all types of applications, from machining

aluminum alloys to brittle materials such as carbide.

■ Hardness

Nano-polycrystalline diamond is a type of polycrystalline diamond, produced

by directly binding nano-level diamond grains without using any binders.

This material is unique to our company, and as compared to

conventional diamond grades containing binders, it exhibits higher

strength, excellent wear resistance and fracture resistance.

SUMIDIA Binderless is the series of tools with cutting edges made

from this high performance nano-polycrystalline diamond.

By using nano-polycrystalline diamond for the cutting edge, these tools achieve

excellent wear resistance and fracture resistance compared to tools made with

previous polycrystalline diamond.

In particular, nano-polycrystalline diamond makes it possible to achieve improved

machining accuracy and long tool life for machining brittle materials such as carbide, etc.

■ Characteristics

● Best suited for high precision machining of carbideAchieves high precision machining of carbide with nano-polycrystalline diamond, which has excellent wear resistance.

● Maintain excellent dimensional accuracy over long periodsGreatly reduces the number of times that the tool must be replaced compared to previous diamond tools, improving work efficiency and

reducing total cost.

● Applicable to machining brittle materialsMakes it possible to perform turning on brittle materials (ceramics, etc.) that could previously only be machined through grinding.
