Abstract

1,235,339. Electrolytic machining and electrodeposition tool. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D' AVIATION. Sept.17, 1968, [Sept.26, 1967], No.44084/68. Heading C7B. Apparatus for the electrolytic treatment of metallic workpieces 2 comprises an electrode tool 1, movable transversely past the workpiece during treatment, a current generator 4, electrolyte supply means arranged to deposit a layer of electrolyte on the surface of the electrode and contrast means which causes a decrease in the thickness of the layer of electrolyte such that a thin film of electrolyte passes through a gap between the tool and the workpiece, the control means being formed either by a rigid or flexible blade urged elastically towards the tool electrode, or by a nozzle for delivering a gaseous jet at high speed against the electrolyte layer. As shown the tool electrode is formed by a disc rotating about its axis and arranged so that the axial support 3 may be moved towards and away from the workpiece. The apparatus may be used for removal of metal from the workpiece or for coating thereof. For use in machining the electrode tool 1 may contain an abrasive.
