Abstract
Material is removed electrolytically from workpieces by means of polyphase current by employing a number of tool electrodes equal to the number of phases of the current source or a multiple of this and passing current between the tool electrodes and one or more electrically interconnected workpieces whilst an electrolyte is passed through the workpiece - electrode gaps, the working tips of the electrodes being electrochemically inert and together with workpiece(s) being immersed in the electrolyte. While several electrically connected workpieces may be acted on simultaneously by locating at least one working tip opposite each workpiece, typically either several separate surfaces of a single workpiece are acted upon simultaneously by locating at least one working tip opposite each such surface or a single surface of a single workpiece <PICT:1055170/C6-C7/1> <PICT:1055170/C6-C7/2> piece is treated by grouping several tool electrode tips together as a unitary structure and insulating them from one another, relative movement being imparted between the workpiece and the electrode tips to remove irregularities in the workpiece surface resulting from the insulating regions between them. As shown three segmental electrodes 42 of copper separated by insulation 46 are supported from a manifold 26 of PTFE or epoxy resin, fed by an electrolyte pressure hose 62, to form an electrolyte feed bore 50 for the working gap, epoxy resin insulating coatings 52, 54 being applied to the bore 50 and the exterior of the electrode segments. The tips 48 of each electrode segment are of electrolytically inert material such as graphite or titanium coated with platinum or rhodium. For electrode arrays of large diameter or thin workpieces a multiple of three electrode segments is provided. The workpiece is rotatably mounted Fig 1 (not shown). In an alternative arrangement, three rectangular copper electrodes 80 separated by insulation 86 and coated on their outer faces with epoxy resin supported from a block of PTFE or epoxy resin and bearing working tips of graphite extending a little beyond the outer margins of the electrode array are disposed to pass through a recessed bushing 76 of PTFE or epoxy resin provided with a number of electrolyte supply pressure hoses 104 and throttled drain hose 110, and adapted to seat in sealing manner on the workpiece, the high electrolyte pressure giving a polished finish to the cavity sunk in the workpiece, e.g. of stainless steel.
