Cubic boron nitride (CBN) is a superb abrasive material designed specifically for advanced wear-resistant characteristics. It is a comparatively recent material innovation which has been earmarked as one of the greatest technological advancements of all time for abrasives. But what makes CBN abrasives so useful in roughing applications?

What is CBN?

Cubic boron nitride, henceforth abbreviated to CBN, is a synthetic crystalline material that is second only to diamond in terms of hardness. It is structurally analogous to diamond too, with a complex cubic/sphalerite structure composed of interpenetrating face-centred cubic lattices.

Essentially, CBN abrasive grains are composed of short, covalent boron—nitrogen bonds which form extremely tight three-dimensional (3D) matrices. These structures are inherently resistant to abrasion, corrosion, and thermal deformation, which makes CBN abrasives ideal for grinding applications.

 

ToolingBox offers different CBN materials to machining different workpiece materials with different hardness. All inserts are ISO standard, also we can produce special insert according to customer's requirement.
