Abstract
<PICT:1063721/C6-C7/1> Balls, cylinders and like articles of circular cross-section are electro-machined in the presence of an abrasive by trapping the balls 19 between two relatively rotatable wheels 11, 14 of which 14 is of an abradant composition and preferably has a groove 18 cut in the face to contain the balls. The wheel 11 is pressed forward by a spring 15, and may be fixed and carries a cover 22 which retains a substantial amount of the electrolyte fed into the axis tube 21. The balls are subjected to both grinding and electrolytic action. The abrasive wheel is impregnated with silver to render it conductive. For an alternative arrangement Figs.2, 3 (not shown) the ball is supported between the edges of Cortia-rotating wheels, one of which is non-conductive and has metal inserts and slip rings, the abrasive being fed in with the electrolyte.
Improvements introduced in the abrasive uses for the electro-earthing, especially electrolytic, of metal parts in manufacture. (Machine-translation by Google Translate, not legally binding)
