Small hole EDM apparatus swash

One kind of oblique hole EDM apparatus, comprising coupling an electrode body yaw axis positioned clamping screw, fastening nut, the hollow shaft and the locating apertures electrode. Yaw axis electrode connecting rod coupling body located within the rectangular slot and is clamped in position by a screw; dial has a rectangular slot on both sides of the coupling body. Shaft positioning shaft hole diameter end of the electrode and the like fastening yaw axis. Rubber seals the electrode axial hole yaw axis. Hollow electrode through the bore hole and the drill chuck is loaded rubber seal positioning shaft. The electrode into the nozzle central yaw axis. The present invention without using the part flip tooling, manufacturing cost and time savings in tooling expand the application range of the current aperture EDM apparatus, improve the machining accuracy, and by the deflection of the shaft structure using realized electrode swing within 0 ~ ± 90 ° range, solves the problem of the dependence of the tooling holes during machining space technology.
