PURPOSE:To double electrode dimensions processible with a rectifying device, receiving device and a control device of the same capacity by electrically dividing an electrode of an electrolytic processing machine with an insulating measure and sending a processed current alternately to a divided current. CONSTITUTION:Alternating current to be inputted to a receiving device 10 is converted into direct current by means of a circuit breaker 11, rectifier 12 and impressed between electrodes 7a, 7b, electrically divided through an insulating plate 6, and a work 13. In addition to gates 16a, 16b provided for turning on thyristors 17a, 17b according to a signal from a gate pulse generator 19, a condenser 18 for turning off thyristors is provided between anodes of the thyristors 17a, 17b. When the thyristor 17a is in conductivity, the thyristor 17b is opened so that a current flows only to the electrode 7a while when a gate signal is given to the thyristor 17b, it is set conductive so that the thyristor 17a is opened. |
