CBN Grinding Wheel

CBN grinding wheelDiamond has been recognized as the best superabrasive to use in the grinding industry. Diamond is the hardest material known, making it ideal as a superabrasive. However, diamond begins to lose its strength under intense heat and workloads. cBN or cubic boron nitride, is a superabrasive that has been specially created to fill in the gaps where diamond fails.


When grinding at high-speed in certain materials such as hardened ferrous materials, like hardened steel, CBN Grinding Wheels have a distinct advantage over Diamond Grinding Wheels. High-speed grinding allows the operator to increased feed rates, thus reduce grinding time, all while the cutting force remains constant. CBN is ideal for high-speed grinding in these materials because of its excellent thermal stability and shock resistance.


CBN has a higher thermal resistance than a diamond. When temperatures exceed 800 degrees, CBN is proven to be harder than diamond using the Thermal Toughness Index (TTi) and CBN is able to maintain its cutting edge well up to 1000 degrees. As well a high thermal resistance, the thermal conductivity of CBN is four and a half times better than copper making it rival diamond.


Why use a CBN Grinding Wheel?

CBN Grinding Wheels are considered the superior choice compared to conventional abrasives such as silicon-carbide and aluminum oxide. The strength and resistance to thermal and chemical attack helps maintain sharp cutting edges, making it the superior choice. As well as beating out conventional abrasives, the high thermal stability makes CBN the best choice for grinding of all varieties of steel alloys, where diamond abrasives are not normally employed. If you would like to read more about CBN Wheels click here.
