PROBLEM TO BE SOLVED: To process a contact lens as an object to be manufactured with high accuracy and high efficiency in manufacture of contact lens. SOLUTION: Manufacturing process for a contact lens 4 is divided into two for an internal circumferential part being a base curve part and for an outer circumferential part. When the internal circumferential part is processed, it is processed by revolution of a swiveling table 7. When the outer circumferential part is processed, the swiveling table 7 that loads a tool 5 stops revolving and the outer part is processed by moving of orthogonal X-Y tables 1 and 2 loading a spindle 3 that revolves the contact lens being an object to be manufactured. Consequently, the contact lens can be manufactured with high accuracy and high efficiency. |
