PURPOSE:To improve mounting accuracy of a work, by forming almost the whole unit of a work mounting device with a metallic member of high mechanical accuracy and firmly mounting a mounting jig to a reference mounting eat in a machining tank interposing no insulating member. CONSTITUTION:A reference mounting seat 3, being provided in a machining tank 2 on a base bed 1, here mounts a mounting jig 4 previously setting a work 13. The jig 4 mounts to its important part an insulating member 5 prepared by, for instance, ceramics or the like. The jig 4, positioning the work 13 by the insulating member 5, holds the work 13 to be clamped by a clamp 6 mounting an electric insulating member 6a of ceramics or the like to a part where the clamp 6 is adapted to the work 13. A fixing arm 7 comprises a base part arm 8, sliding arm 9, mounting thread 10 and a pressing member 12 or the like. For fixing the jig 4 to the mounting seat 3, a mounting device, moving the arm 9 to be fixed by a handle 11 so that the pressing member 12 is placed in a predetermined position, fixes the jig 4 to the mounting seat 3 through the pressing member 12. |
