CBN Borazon Wheel
Borazon is a brand name of a cubic form of borazon nitride (cBN). Borazon gives CBN Wheels a color tint that can range from black to brown and even gold depending on the bond that was used on the wheel to adhere the superabrasive to the core. CBN is a man-made material that rivals the hardness of diamond and even has the same crystal structure as diamond. The biggest difference between Diamond and CBN is seen atomically in the crystal structure itself. Diamond crystal structure, bonds between carbon atoms whereas CBN replaces the carbon atoms with borazon atoms. The reason that CBN is such a superior superabrasive is due to this difference in the atoms of the crystal. Diamond is not as efficient machining ferrous materials because the carbon atoms chemically react with the carbon in the material being worked on. CBN Borazon Wheels are able to grind away ferrous materials with ease because the borazon atoms do not chemically react with the ferrous materials.
Although Diamond may be the hardest material, it doesn’t always remain hard under high temperatures. At around 700 degrees, Diamond begins to break down and lose its hardness. CBN, however, keeps its hardness, even when machining temperatures exceed 1,000 degrees! With the high thermal stability of a CBN borazon wheel, high speed grinding is not problem.
How often should I replace my CBN Borazon Wheel?
CBN Borazon wheels are such a superior product, that the only limiting factor of the life of the wheel is the bond that holds the superabrasive to the core. The breakdown of the wheel occurs when the bond, begins to erode and loses its grip on the cBN particle, tearing the cBN out. However, as cBN is removed, new particles of cBN are exposed, continuing the grinding effectiveness of the wheel. Our superabrasive wheel lineup contain bonds that are formulated in house by our chemist and engineers. We pride ourselves in the superior strength of our bonds and our team of chemist and engineers are constantly developing and testing new bonds to ensure the integrity of our wheels.
