Abstract
A method and apparatus is described for producing a large number of identical parts from a bar of material by electrochemical machining without the intervention of an operator. The apparatus comprises a spindle for supporting the bar and periodically feeding it in the direction of its axis, and an electrochemical machining assembly comprising cathodes for shaping the leading end portion of the bar to form the part. After the part has been shaped, it is electrochemically cut from the bar, and the bar is advanced longitudinally by the spindle in order to proceed with the machining of the next part.
