SUMIBORON BINDERLESS, nano-polycrystalline CBN, for cutting edges.

High efficiency and high precision machining are possible due to the use of the CBN tools with no binders.

Suitable for high efficiency finishing of exotic alloys such as titanium alloy, Co-Cr alloy, etc.

Outstanding wear resistance is achieved by the excellent hardness and thermal conductivity of nano-polycrystalline CBN.

Superior dimensional tolerances and machined surface roughness over many hours

Less tool replacements compared to conventional grades will improve work efficiency and reduce total costs.

SUMIBORON BINDERLESS are CBN with nano to submicron CBN grains bound tight and no binders.

The higher hardness and improved thermal conductivity compared to conventional CBN grades ensure higher efficiency and longer tool life for use with exotic alloys such as titanium alloy and Co-Cr alloy.
