Patent EP-0027040-A1 (EP)
Inventor: OBARA HARUKI
IPC: B23H1/02
Filed: 1980-10-03
Abstract: The power source has a transistor-capacitor discharge circuit with a power supply V 2 , a resistor R, a control transistor Tr and a plurality of capacitors C 1 , C 2 , C 3  each connectable in parallel with wire electrode WIR and workpiece WK. Inductors L 1  and L 2  are provided in series with capacitors C 1  and C 2 . A stray inductance is effective in series with capacitor C 3 . Switches S 1  to S 3  switch in the capacitors C 1  to C 3  selectively. The capacitors increase in value from C 1  to C 3 , and the inductances L 1  L 2  and the stray inductance correspondingly decrease in value. 
     Eache capacitance value is appropriate to a different machining operation, i.e. C 3  for rough machining, C 2  for medium machining and C 1  for finish machining. 
     By the use of different capacitors, and corresponding inductances, cutting speed can be maintained in each different machining operation.
