Chemical Vapor Deposited Diamond Dressers

Diamond is extensively used for the dressing of precision grinding wheels. The grinding process using conventional, diamond and cBN abrasives is extensively used in the finishing of ferrous, tungsten carbide and ceramic components. Here, the geometrical tolerance, the surface finish of the wheel and its condition is critical and the dresser s function is to achieve and maintain these characteristics. 

CVD diamond has been compared to single crystal synthetic diamond in single point dressing tests. The conditions and results of these tests are described below. 

From Fig. 42 it can be seen that CVD diamond exhibits almost identical rates of wear compared to single crystal synthetic diamond. Effectively this means that CVD diamond offers a range of geometric and orientation advantages in dresser design without having to compromise on the wear resistance of the dresser.
