MACHINING TOOL FOR GLASS LENS AND MACHINING METHOD FOR GLASS LENS

摘要: PROBLEM TO BE SOLVED: To prevent damage to a polishing plate in time of polishing, by providing an oscillating support part for supporting glass blank be machined and rotating state process with the kept holding state. SOLUTION: A lens 2 is rotated grinding hold member held tool 6, while ground rotational movement machining grinding. After completed, set into device without removal from 6 so as succeedingly polished. 14 attached main spindle side oscillated that sheet 16 polishes optical surface 2. The transmitted pressing 18 having curved 18A fitting on 6F dependently rotated.
