PROCESSING METHOD FOR SAPPHIRE CURVED SURFACE WINDOW WITH CYLINDRICAL GRINDING METHOD

摘要

A processing method for a sapphire curved surface window comprises the following steps: cutting a curved surface of a sapphire wherein an external angle is processed with a diamond wire saw; bonding the cut sapphire on an external surface of a cylindrical external surface processing jig with wax; grinding and polishing an external surface of the curved surface sapphire with a cylindrical external diameter grinding method; separating the sapphire from the external surface processing jig by using heat; bonding the curved surface sapphire on a cylindrical internal surface processing jig with wax; grinding and polishing an internal surface of the curved surface sapphire; and separating the sapphire from the internal surface jig by using heat.;COPYRIGHT KIPO 2015
