Zusammenfassung:PROBLEM TO BE SOLVED: To achieve the electrical discharge machining of low consumption electrode type for finishing the hard-cutting material such as cemented carbide and hardened steel. SOLUTION: A copper tool electrode is cathode, and a work 6 made of hard-cutting material such as cemented carbide and hardened steel is anode, and the work 6 is electrical discharge machined in the insulating machining fluid by the electronic impact by the unipolar high current density spark discharge in which the discharge time is so short for the cathodic iron is difficult to reach the tool electrode 8 and the peak value of the discharge current is increased to the discharge time.
