Spark erosion machine

摘要

The spark erosion machine produces an electric discharge in a space between an electrode (5) and a workpiece (4) in such a way that a saturable reactance (111, 112, 113) is included into the line (8) serving for delivery of machining energy from a source (7) to the electrode (5) and to the workpiece (4). Such a reactance (111, 112, 113) is excited by a current which is inverse to the discharge current.
