Claims

[Claims for Utility Model Registration] (1) Attach an electrode blank in which a formed electrode for electric discharge machining is to be formed to a reference piece having a reference surface that serves as a position reference during electrode forming, and place the above-mentioned electrode blank in the holder of an electrode forming machine. In an electric discharge machining system provided with a mounting reference surface that engages with a reference surface of a reference piece to hold the reference piece, a stud bolt is fixed to the reference piece, and the holder is connected to a holder body having the mounting reference surface. ; a movable shaft member supported movably in the axial direction on the holder body; and a movable shaft member that opens in the mounting reference surface and is bored across the holder body and the shaft portion of the movable shaft member;
an insertion hole for the stud bolt; a means for preventing the stud bolt inserted into the stud bolt insertion hole from coming off the movable shaft member; A holder system for electrical discharge machining, characterized by comprising a close contact holding mechanism that brings the holder into close contact with the holder. (2) In claim 1, the means for preventing the stud bolt from coming off and the tight holding mechanism include: a lock member sliding hole formed perpendicularly to the stud bolt insertion hole of the movable shaft member; the lock member sliding hole is movable into and out of the lock member sliding hole; Supported by
a lock member having a claw portion that engages and disengages from the small diameter portion of the stud bolt; a circular hole bored in the movable shaft member in a direction perpendicular to the stud bolt insertion hole; a lock member that is rotatably inserted into the circular hole; A lock shaft having an eccentric shaft portion to be fitted into the lock shaft and a rotation shaft portion eccentric to the eccentric shaft portion; a support hole formed in the holder body rotatably supporting the rotation shaft portion of the lock shaft; A holder system for electrical discharge machining consisting of.
