Title: Electric discharge machining apparatus
Inventor: INOUE KIYOSHI
IPC: B23H1/04
Filed: 1980-05-15
Abstract: PURPOSE: To obtain high precision machining by a method wherein an electrode for electric discharge machining is composed of a heat resisting tube with metal pieces filled up therein and transmits electricity by applying pressure to the metal pieces at the opposite end to the working end with an electric current transmitter to successively replenish the tip wear of the electrode occuring during the machining.  
     CONSTITUTION: Working pulses are applied from a pulse source 3 between the electrode 1 and a workpiece 2. The machining of prescribed form is performed by controlling an X-axis motor 5, a Y-axis motor 6 and a Z-axis motor 7 with an NC control unit 4. The electrode 1 is composed of the tube 11 made of heat-resisting materials such as Al 2 O 3 , graphite or the like with particulate metal pieces filled up  therein. Electricity is transmitted through the metal pieces by pressing the upper  part of the metal pieces 12 with the electric current transmitter 13 pressed by a  spring 14. The vibration of the electrode or application of magnetic field with a coil  8 is also possible during the machining. As the wear of the metal pieces at the tip of  the electrode occuring during the machining can be successively replenished and the  tip of the electrode can be kept at the constant position, so the high precision  machining is possible.
