Abstract
Grinding performance of fine abrasive grinding wheel to Quartz-Crystal were investigated. The grinding wheel were fabricated using a ElectroPhoretic Deposition phenomenon, it was called EPD pellet. In this study, Silica and Alumina powder were applied as abrasives for EPD pellet. Mirror surface about 10nmRy could be obtained by Silica and Alumina EPD pellet, but Grinding efficiency of Silica EPD pellet were better than Alumina.
