Abstract
PURPOSE:To form the same curve on works even when a plurality of works having different thicknesses are simultaneously attached for machining by a method wherein after the works are brought into pressure contact with a polishing surface plate through the force of respective press means disposed internally of a containing part, the work is secured to the containing part, and the center of a concentric circle is microdisplaced approximately in a vertical direction to the polishing surface plate. CONSTITUTION:Works 22 are contained in respective containing parts 2 arranged on the concentric circle of a lower resilient member 10 of a jig for machining mounted facing a polishing surface plate 20. After the works 22 are forced into press contact with the polishing surface plate 20 through the force of a press means (spring) 4 disposed internally of the containing part, the work is fixed to the containing part 5 by means of a fixing screw 6. The center if the concentric circle is microdisplaced approximately in a vertically direction to the polishing surface plate 20 by means of a piezo-electric element 16. This method forms a microslope or a curve on the work piece 22 with high precision without bringing the piezo-electric element 16, being a microdisplacing means, into direction contact with the polishing surface plate 20.
