Abstract
Sapphire has superior characteristics, such as hardness, chemical stability and high wear resistance. Therefore, processing to sapphire is very difficult. By the way, it is known that the sapphire can react with silica and iron oxide at high temperature and high pressure. Using these phenomenons, mechano-chemical polishing to sapphire was performed by silica and iron oxide. Glass was selected because glass is containing silica. S45C and SUS304 were selected as ferrous material. In this study, First, machined volumes of sapphire using each material and processing atmosphere were compared. Second, machined volume of sapphire was examined when using ferrous material, and changing the feed rate and cutting speed. Finally, it was possible to combine roughing with SUS304 and finishing with glass.
