ABSTRACT:
An apparatus for spark-erosive planetary eroding of a workpiece in which an eroding electrode is lowered into the workpiece as the workpiece is eroded and the workpiece and electrode carry out planetary motion with respect to each other so the operation gap between the narrow periphery of the electrode and the workpiece moves around the periphery of the electrode during planetary motion. A plurality of injection nozzles are positioned around the gap for supplying liquid dielectric thereto in accordance with the planetary movement. A plate having bores therethrough closes a chamber containing such liquid with each bore supplying a nozzle. The bores terminate at a wall of the chamber so that the opening into the chamber and therefore the supply to each nozzle is varied in accordance with the planetary movement.
