Abstract: In the construction industry, the decorative value of natural granite material depends mainly on its colour and surface glossiness, which are separately lien on its natural mineral components and the machining process. In order to find the mechanism of generating high glossy surface for the natural granite, grinding of several brittle materials with the Electrolytic In-process Dressing (ELID) system were conducted to get super smooth granite surfaces in this study. The surface roughness after grinding with different mesh size diamond wheels was examined to describe the surface characteristics for natural granites. According to the inherence of these brittle workpieces and measured surface roughness in the grinding tests, the surface roughness characteristics of granite grinding were discussed.

Keywords: brittle materials; ELID grinding; granite; surface roughness; electrolytic in-process dressing; surface finishing; construction industry; granite colour; surface glossiness; glossy surfaces; diamond grinding wheels.
