CBN cubic boron nitride insert  is the best tool material in the field of ferrous metal processing.

It has been proved that the life of cbn turning inserts is usually several to ten times that of carbide inserts and ceramic inserts. It is not difficult to simply improve the hardness 

and wear resistance of cubic boron nitrite cutting tools, but as the tool material hardness increases, the brittleness increases and the indexable cubic boron nitrite insert toughness 

decreases.

CBN insert is a fragile super-hard tool material. Its high hardness is its most obvious characteristic, and toughness is its most basic guarantee, but we could not lose its super wear 

resistance due to the pursuit of toughness, and regardless of the impact resistance, we cannot blindly pursue its high hardness and tool life of the tool. LINKUT solid cbn inserts or 

tipped pcbn inserts could help you realize the highly balanced processsing efficiency.
