Abstract: Diamond cup wheel is one of important tools for machining of ceramic tile. In this paper, ceramic tiles were ground by diamond cup wheels which segments adding nano-scale rare-earth oxide and nano-scale carbide on a special designed test machine. The wear resistance of diamond cup wheels and materials’ removal process of ceramic tiles had been tested, and grinding ratio were calculated and compared. Different grinding ratios can be obtained according to different technological parameters. The segments of adding nano-scale rare-earth oxide and nano-scale carbide were observed from microgram and metallography structural pattern. The results showed that nano-scale rare-earth oxide and nano-scale carbide can fine structure, make grain boundary clear and increase grasping of diamond grits.

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.

Abstract: As one of the excellent decorative materials ceramic tiles must be ground and polished to present the glossy surface. In this paper the ceramic tiles were edge ground by diamond cup wheels in the special designed test machine. The surface morphology of the polished ceramic tiles and the wear of diamond cup wheel were examined by Scanning electron microscopy (SEM). The wear resistance of diamond cup wheel and the materials’ removal process of ceramic tiles had been tested. The results showed that the wear of diamond cup wheel was stable when grinding with high grinding ratio. The ground surface showed that only the fracture of ceramic tiles was acted by diamond grits during grinding with water by means of good quality diamond cup wheel.
