Zusammenfassung:	PROBLEM TO BE SOLVED: To reasonably machine the circumferential edge of a spectacle lens by means of a straight grinding wheel b1 and a taper grinding wheel b2. SOLUTION: A machining device mechanically shifting a relative position and a relative angle θr between a grinding wheel turning shaft 41 and lens turning shafts 8a, 8b is formed, and the straight grinding wheel b1 and/or the tapered grinding wheel b2 are/is fixed to the grinding wheel turning shaft 41, while a material lens Re is clamped by the lens turning shafts 8a, 8b in machining.
