Claims

[Scope of utility model registration request]

A machining liquid is interposed between the electrode and the workpiece, and a machining voltage is applied between the electrode and the workpiece to generate an electric discharge in the gap between the electrodes and the workpiece, and this discharge energy is used to generate a discharge. An electric discharge machining device for machining a workpiece with a fluid supply means separate from the fluid supply means for supplying machining fluid in a machining fluid tank to the gap between machining surfaces, and supply of machining fluid by the fluid supply means. A machining tank is provided with a suction means for generating suction pressure by a vacuum cleaner, and is composed of an insulating hose for connecting the suction means and the electrode, and in which the workpiece is placed and the machining fluid is stored. An electrical discharge machining apparatus characterized in that a machining fluid presence/absence determining means is provided at a higher position than the provided machining fluid presence/absence determining means.
