ABSTRACT:
This disclosure relates to the refeeding of one or more electrodes of an electrical discharge machining apparatus after the electrodes have been used and unevenly worn. The electrodes are mounted within a cartridge which includes an element which offers frictional resistance to the movement of the electrodes relative to the cartridge so that when the cartridge is advanced to engage the electrodes with a workpiece the electrodes are automatically recessed within the cartridge until the tips of all electrodes are aligned. A clamp is provided for then securely clamping the electrodes against further movement relative to the cartridge.
