ABSTRACT:
An EDM apparatus for high speed machining of a workpiece and redressing of a graphite electrode by an ultrasonic machining tool or a total form machining tool. When the electrode becomes worn the workpiece clamped on a table (1) is shifted away by a slideway mechanism (4) so that a master on another table (2) confronts the worn electrode. The electrode is then redressed and the workpiece is slid back into position by the slideway mechanism (4) for more machining by the redressed electrode.
