ABSTRACT:
A small-hole electrical discharge machining device comprises a diaphragm which can be moved up and down along a notch window provided in a work tank for mounting a work in the work tank in which a working fluid can be filled or discharged, and adjusts the height of the working fluid; a W-axis slide which can be moved up and down, and having an electrode guide in the lower end portion; a master cylinder which is moved up and down corresponding to up-and-down movement of the W-axis slide; and a slave cylinder which is connected with the master cylinder through a pipeline and with a diaphragm driving mechanism, and wherein the diaphragm is moved up and down corresponding to up and down movement of the W-axis slide.
