摘要： The present invention discloses an improved electrode assembly and electrochemical drilling machine for drilling small diameter holes. The electrode assembly includes a metallic working electrode tube having an inlet end for electrolyte entry and an outlet end for drilling, the tube having preselected dimensions to provide the desired diameter and depth of hole. The assembly also includes a filter tube one end portion of which defines a plurality of individual access openings for electrolyte entry from an electrolyte source, each opening having a smaller cross section than the bore of the working electrode tube to filter out particles in the electrolyte which could clog the electrode tube and the other end of which is in fluid communication with the inlet end of the electrode tube for delivering filtered electrolyte thereto. Connector means are provided for releasably and sealably connecting the electrode tube and filter tube, enabling the electrode tube to be removed, if damaged or otherwise defective, without disconnecting the filter tube from the electrolyte source.

摘要： In electro-erosion machining using a filamentary erosion electrode, a dielectric flushing medium (for spark-discharge erosion) or an electrolyte fluid (for electrochemical erosion) is fed from an outlet to the working area of the electrode in the direction of the electrode axis and in contact with it so as to cool the electrode and to reduce changes in the machining characteristics with changes in cutting direction. A continuously operable regenerating system, including deionising apparatus which is brought into, and out of, operation under the control of a conductivity measuring device, is provided for regenerating the used dielectric flushing medium in spark-discharge erosion machining.

摘要： Apparatus for and a method of electro erosion machining with increased stock removal rate with a fine finish is disclosed. The electro erosion machining apparatus disclosed includes an electrode having a plurality of separate portions insulated from each other and separately connected to a single source of pulsed electrical energy whereby the current from the source of pulsed electrical energy is divided among the separate electrode portions to provide a small current for each electrode. The method of the invention includes varying the current passed through each portion of the electrode, limiting the current through each portion of the electrode to a single direction and moving the electrode transversely of the direction of movement of the electrode toward a workpiece during electrical erosion machining to provide rapid total form machining.
