摘要
Diamond cup wheel is used widely as an important tool for machining ceramic tile.In this paper,nano rare-earth oxide and nano carbide were added in the segments of seven kinds of diamond cup wheels.The performance of diamond cup wheels were tested on a special designed test machine by grinding two kinds of ceramic tiles.The surface morphology of the segments was examined by Scanning Election Microscopy(SEM) and the micro-hardness of segments was measured.The results showed that nano rare-earth oxide and nano carbide can fine segment micro structure,make grain boundary clear and increase grasping of diamond grits.They can increase also the wear resistance of diamond cup wheels as well as the grinding ratio.
Diamond cup wheel is used widely as an important tool for machining ceramic tile. In this paper, nano rare - earth oxide and nano carbide were added in the segments of seven kinds of diamond cup wheels. The performance of diamond cup wheels were tested on a special designed test machine by grinding two kinds of ceramic tiles. The surface morphology of the segments was examined by Scanning Election Microscopy （SEM） and the micro-hardness of segments was measured. The results showed that nano rare-earth oxide and nano carbide can fine segment micro structure, make grain boundary clear and increase grasping of diamond grits. They can increase also the wear resistance of diamond cup wheels as well as the grinding ratio.
