PCT No. PCT/JP94/01685 Sec. 371 Date Aug. 14, 1995 Sec. 102(e) Date Aug. 14, 1995 PCT Filed Oct. 7, 1994 PCT Pub. No. WO95/10383 PCT Pub. Date Apr. 20, 1995A magnetic adsorption device in a work tank removes machining chips produced as a result of electrical discharge machining so that chips will not enter the gap formed between the tool electrode and the workpiece, ensuring stable machining. When using a dielectric fluid into which a powdered material has been mixed to machine the workpiece, an agitator is used which prevents the settling of the powdered material. The agitator prevents the chips from settling and are prevented from becoming suspended in the dielectric fluid along with the powdered material. The adsorption device preferably contains multiple elongated columnar magnetic bodies positioned to surround the workpiece about its sides.
