た。2. Description of the Related Art In the conventional precision electric discharge machining, jigs such as a precision vise and a precision magnet block have been used for mounting a small work, but a small work can be accurately and quickly processed by a method suitable for a processing method. It was extremely difficult to attach to the surface.Especially in the production of molds, there are small square pins with different aspect ratios and large aspect ratios. After processing, the work of accurately setting the work on the measuring table to measure the work with a microscope etc. is performed every time, and depending on the result, additional work occurs and the work of setting the work table again is repeated daily. Is very inefficient,
In addition, each worker is required to be careful in order to maintain the finishing accuracy in each process, which places a heavy burden on the workers.

る。In precision electric discharge machining, it has been difficult to accurately set a small workpiece on a machining table in a short time in accordance with a machining method. (B) When a precision vise is used When the work is pressed against the reference surface and tightened with a push screw, a force is applied to the nut attached to the base surface perpendicular to the reference surface and the base surface is deformed and accurate. A stable set could not be made. (B) The precision magnet block attracts the work with magnetic force, so the adsorption of the small work with a small suction area becomes unstable, and the distance between the magnet and the work is short. There was a restriction on usage because it fell. (C) When processing by bonding the work to the reference block,
Peeling after processing takes a long time, and there are many accidents in which the workpiece is deformed during the removal of the adhesive or peels off during processing, and the processing lacks stability and reliability. (D) There was no high-precision mounting jig in consideration of small workpiece measurement after processing. (E) No small workpieces were easily mounted and had high repeatability. The present invention has been made to solve the above drawbacks.
