ABSTRACT:
The apparatus for electrochemical machining of workpieces comprises an electrode tool adapted to be fed during a machining operation toward the workpiece mounted on a work table and to be retracted from the workpiece for an inter-operation interval, a pump arranged in a common line upstream of the point of branching off of the working line for supplying the working fluid from a tank to the workpiece and of a bypass line for circulation of the fluid through an intermediate vessel into the tank for the fluid, and also a line switching control means connected with the control elements of individual valves mounted in the working and bypass lines, the means having two rods rigidly connected with the electrode tool and extending in the direction of the feed of the latter, their length being adjustable, the individual valves being fixed on the work table, each under the respective one of said rods, for interaction of the rod with the control element of the respective valve, as the electrode tool is being fed toward the workpiece, the valve in the bypass line being adapted to close this line, as the rod acts upon the control element thereof, and to open the bypass line, when the last-mentioned action ceases, the valve in the working line being arranged for a reverse performance.
