摘要： An EDT apparatus 1 is disclosed, comprising a dielectric fluid return system for use with an EDT machine of the type in which the workpiece is not submersed in dielectric fluid. The return system comprises a first collector 19 for catching spills from a dielectric bath 9 associated with a set of electrodes 10 which apply electrical pulses to the workpiece through the dielectric fluid in the bath. Also, a separate, second collector 21 is positioned substantially beneath the workpiece and arranged both to receive fluid from the first collector 19 and to catch fluid that drips from the workpiece itself, the second collector being connected to a pump 13 which returns the fluid from the second collector to the dielectric bath.
