A methodology for the evaluation of CBN abrasive grits

A better understanding of the grinding process is essential for newly developed grit types. Mapping the effect of grain properties to the application performance is the ultimate goal of every grit manufacturer. The challenge is, however, to provide crucial information about the grit and, at the same time, distinguishes it from other possible effects such as: porosity, adhesion and bond strength. A series of grinding tests have been conducted using different grit types and bond systems and a novel testing methodology implemented. The results have shown good sensitivity with respect to the grain properties and, consequently, the potential application of this method to grinding process optimization
