Abstract
1,237,324. Electro-machining apparatus. ANOCUT ENG. CO. Sept. 9, 1969 [Sept. 24, 1968], No. 44539/ 69. Addition to 1, 219, 957. Heading C7B. The apparatus of the parent invention, in which relative movement between a hollow shaping cathode 201 and a metal workpiece 203 is controlled to maintain a predetermined gap 235, through which electrolyte flows under pressure, (e.g. via region 233 from inlets 231), using drive means with load compensating means for opposing the tendency to relative retraction between the cathode and workpiece produced by the electrolyte pressure, is modified in that the load compensating means comprises a cover 221 enclosing the cathode and workpiece and defining a sealed chamber 225 supplied with pressurized fluid e.g. via passage 246 to exert pressure behind the back surface 226 of the cathode, the cathode being movable with respect to the cover e.g. by being secured to the end of at least one push-rod 217 passing through an annular seal 247 in the cover. The electrolyte may be drained from the work-gap 235 through a plurality of outlet flow channels in the cathode comprising slots 236 (some leading to chambers 237 in cathode high areas 255), passing into horizontal channels 239 in the cathode's adapter plate 212, then into radial and vertical channels 241, 243 in push-rod 217, and out by exit ports 245. Alternatively, some of the electrolyte flow channels may act as inlets, others as outlets, with respect to the work area. The electrolyte flow may be blocked through the cathode low areas 257 until machining has proceeded to such a degree that these areas are close to the work-piece. Various insulating members of the apparatus, e.g. pad 253 covering underside of work-piece table 204, top of ram head 219, spacer 205, walk 207 and supports 223, are preferably made of epoxy resin - glass fibre composite.
