  • Method and pulse-forming device for electrical discharge machining
    Patent number: 10399164
    Abstract: A method for electrical discharge machining a work piece using rectangular processing pulses includes forming the rectangular processing pulses by discharging one or multiple discrete delay lines that comprise multiple storage elements. The storage elements are arranged as part of a feed line to a spark gap on a section of the feed line near the spark gap. The discrete delay lines are connected to a guide head by an electrode-side contact unit and are connected to the work piece by a work piece-side contact unit.
