摘要： A dielectric fluid system (2) for an electric discharge machining apparatus comprises an auxiliary tank (22) positioned higher up than a work tank (12) on a dielectric fluid reservoir (21), a filter device (23), and a first pump (P1) and a second pump (P2) upstream and downstream of the filter device 23. Dielectric fluid in the dielectric fluid reservoir (21) is filtered by the filter device (23), and pumped to the auxiliary tank (22) using the first and second pumps (P1) and (P2). The filtered dielectric fluid is then rapid fed from the auxiliary tank (22) to the work tank (12). During electric discharge machining, dielectric fluid is pumped from the work tank (12), filtered, then cooled and circulated directly back to the work tank (12). A flushing pipeline and a third pump (P3) are added into the circulating pipeline. Also, a relief pipeline (K) containing a relief valve (RV) is provided in parallel with the filter device (23), and regulating pipeline (H) is provided as an effective safety measure in parallel with the first pump (P1) and the filter device (23).

摘要： 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.

摘要： A liquid level regulator which can regulate easily and accurately a liquid level in a discharge machining tank. The regulator includes a discharge pipe (10) communicating with a machining solution discharge port (3) of a discharge machining tank (1) and a regulation pipe (20) which fits slidably into the discharge pipe (10). An O-ring (30) is discharged in an annular groove in a lower part of the outer peripheral wall of the regulation pipe to be brought into pressure contact with the inner peripheral surface of the discharge pipe. When an operator holds a rod (40) projecting upward from the regulation pipe, slides the regulation pipe with respect to the discharge pipe (21) and positions its upper open end (21) to a predetermined height, the regulation pipe is held at this height by the O-ring. When a machining solution is supplied into the machining tank and the liquid level reaches the upper end of the regulation pipe, the machining solution overflows from the machining tank through the upper end of the pipe and is discharged outside the machining tank from the upper end of the pipe through the regulation pipe and the discharge pipe. Then, the supply of the machining solution is stopped and the liquid level regulation is completed. Leak of the machining solution from the machining tank is prevented by the O-ring and a substantial drop of the liquid level does not occur.
