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.
