The purpose of this paper is to provide the optimal grinding conditions of metal components of a spectacles. The main elements of grinding conditions are composed of grain size, grade, structure, grinding wheel velocity and shifting components velocity. The conditions are co- related and influenced at each other. The precision of grinding surface was controled the each grinding conditions, mutual relations and reciprocal actions. It was studied the co-relations of grinding conditions those machining time-grain size-roughness, grade-roughness, machining time-characteristics of structure- roughness, number of production-roughnessgrinding wheel velocity, number of production-shifting velocity-grinding wheel velocity. The optimal grinding working condition satisfied the demanded surface accuracy 0.5 ~ 1.5μm. Based on these results, the optimal conditions were that the grain size was 60, the grade was middle of HIJK and LMNO, wheel velocity was 25 m/sec, shifting velocity was 15 m/min.
