Abstract
A wire cutting type electrical discharge machining system in which a work pan can be made smaller in size than that in prior art by virtue of changing its structure. The device has (a) a work pan for supporting a workpiece therein including a side wall which has an elongate aperture extending horizontally and having guide grooves along upper and lower sides of the elongate aperture, (b) a lower arm extending laterally through the elongate aperture inwardly into the work pan as far as below the workpiece, (c) a closure strip disposed along the elongate aperture for closing it substantially fluid-tightly by being guided in the guide grooves, top and bottom, and provided with a hole in a longitudinally central position thereof for allowing the lower arm to slidably extend therethrough, and (d) annular sealing means disposed in the closure strip for allowing the lower arm to move fluid-tightly in the longitudinal direction thereof. The lower arm can freely move in any desired direction while being well sealed in the compactly made work pan.
