PURPOSE:To perform practicable electromagnetic working over a wide range with simple constitution by conducting electric current from a storage device to a flat plate-shaped coil, and processing a work by making use of the electromagnetic repulsive force. CONSTITUTION:Electric current is conducted impulsively at a desired positional relation or desired timing from a storage device 9 to a flat plate-shaped coil 5 and a work 13 positioned below a coil holder 3 is processed by making use of the electromagnetic repulsive force. The holder 3 is equivalent to the slide of an ordinary press machine. Therefore when the slide position is in an upper part, a switch is turned on and a capacitor is charged. When the slide position descends and attains the prescribed distance from the work, the switch is turned on to actuate a switching mechanism, thereby an electric discharge switch is turned on. |
