<p>An electric discharge machining device adapted to remove machined chips resulting from electric discharge machining by provision of an attraction device containing magnetic material in a work tank so as to eliminate a risk of machined chips penetrating into a gap formed between an electrode of a tool and a workpiece, a stable machining being thereby secured. In a case where a workpiece is machined by using an induction liquid containing powder material, a stirrer is provided for preventing settling of the powder material. This stirrer prevents machined chips from floating together with the powder material in the induction liquid without settling. The attraction device includes a plurality of long cylindrical magnetic materials and is preferably disposed so as to surround a workpiece from the side thereof. <IMAGE></p> |
