CBN is really a new style of superhard material with ultra-high pressure and high temperature technology after synthetic diamond using . CBN and its particular products are mainly appropriate for precision grinding of tool steel, alloy steel, heat-resistant steel, stainless and other materials. Although the pricing is slightly greater than that of general abrasive grinding wheel products, thermal stability and chemical inertness can be better than general abrasive wheels, diamond wheels, etc. Vitrified bond CBN grinding wheel at superabrasivetools are routine used wheels during grinding process.



Grinding performance of grinding wheels is unique with diamond, CBN, silicon carbide and corundum abrasive. Diamond will be the hardest abrasive, but it’s not ideal used by steel material with large grinding toughness because of poor thermal stability. Silicon carbide wears rapidly as a result of its low hardness and chemical activity to iron group metals. Corundum is really a conventional abrasive used by grinding steel material, even so the hardness is pretty low.
