Abstract

1,170,644. Electro-machining or - polishing. VUMA, VYSKUMNY USTAV MECHANIZACIE A AUTOMATIZACIE. Sept.27, 1967 [Sept.29, 1966], No.44015/67. Heading C7B. An apparatus for electro-broaching or - polishing openings in a workpiece 20 using a tool electrode 22, which is separated from the adjacent surface to be worked in the workpiece opening by at least one insulating e.g. ebonite guide projection 24 or spacing cylinder (33, Fig.2) fitted to the electrode or by a flow of electrolyte over a suitably shaped electrode, comprises two spaced apart electrolyte chambers 34, connected to electrolyte inlet and outlet conduits 40, 39 respectively, and inter-connected by the workpiece, with a control mechanism, e.g. a slide block 30 and a sheathed pull rod 27, attached to the electrode for moving the electrode into engagement. The cross-section along the electrode may vary to enlarge a circular opening or form a rectangular opening from a circular one.
