Cbn grinding wheels

Cbn grinding wheels are graded by the hardness of the bond. A higher-hardness bond allows for longer wheel life when compared to conventional grinding wheels, such as aluminum oxide and silicon carbide.

To determine the hardness of a wheel, one must first understand how the abrasive grit works.  if the working material is easy to cut, a high-hardness wheel is suggested. A softer wheel is used for a more difficult to grind materials, such as sub micro-grain TCT cutting tools.
