Study of Surface of Edge Grinding of Ceramic Tile by Diamond Cup Wheels

Abstract

As one of the excellent decorative materials, ceramic tiles must be ground and polished to present the glossy surface. Diamond cup wheel is one of important tools. Ceramic tiles were ground by diamond cup wheel with a special designed test machine. The materials’ removal process of ceramic tiles had been tested, and surface roughness was measured. The surface micromorphology of the polished ceramic tiles under different depth of grinding and feed speed was examined by Scanning Electron Microscopy (SEM). The results showed that a lot of materials’ removal can be obtained by increasing the depth of grinding and feed speed in rough process of ceramic tile. On the contrary, good surface can be obtained by reducing depth of grinding and feed speed in fine process of ceramic tile.
