In the present study, natural granites were ELID ground with metalresin bonded diamond wheels on a lapgrinding machine to achieve smooth surface. The surface roughness during the grinding process and final glossiness were examined to describe the formation of finely finished granite surfaces. According to the detailed microobservation of ground surfaces, it can be concluded that natural ...
