Abstract

765,101. Electrolytic grinding apparatus. NORTON GRINDING WHEEL CO., Ltd. Feb. 24, 1954 [April 28, 1953], No. 5417/54. Class 41. A wheel 15 for an electrolytic grinding apparatus comprises an electrically conductive disc having a central hole and a plurality of radial passages 17 extending from the hole to openings 22 in the circular face of the wheel 15. Electrolyte 90, e.g. salt water or one of those described in Specification 491,023, [Group XVIII], is delivered by a diaphragm pump 85 from a tank 80 having rubber walls through a dome accumulator 74 and pipes 73, 66 to the pipe 60 in the hollow spindle 25. From here it passes through radial holes and arcuate slots in the end of the spindle 25 to the radial passages 17 and the openings 22. A motor 57 drives the spindle 25 through pulleys 55, 53 interconnected by insulating belts 54. Current is supplied to the wheel 15 through leads 115 connected to brushes 112 urged by springs 113 into contact with the wheel. The bed plate 11 is connected to the positive terminal of a battery, leads 115 to the negative terminal. The wheel may consist of a metal back plate 16 and a metal front plate 18 bolted together, the plate 18 having an annular part 21 containing the holes 22. The abutting face of the plate 16 is grooved to form the channels 17. Alternatively the wheel 15 may comprise a grooved metal back plate 135 and a front plate 138 bolted thereto to form radial channels 136, Fig. 4, an annulus 141 of porous recrystallized silicon carbide being held between annular rims 137, 140 on the plates. If desired, a wheel-eroding cathode 120, e.g. of tungsten carbide, may be resiliently held by a spring steel bar 124 against the operative face of the wheel 15. The cathode 120 and the brushes 112 are connected in parallel, e.g. through variable resistances, to the negative terminal. Specification 556,527, [Group XXIII], also is referred to.
