Disclosed is an automatic control system of the regular current for electrolytic inprocess dressing. The system comprises a direct current power supplier(8), an interval converter(7), an analog to digital converter(10), a computer(12), a digital to analog converter(11) and a connection board(9). The interval converter(7) which is biased by the power supplier(8) converts the electrode interval value of a metal bond base(1) into an analog interval signal. The analog to digital converter(10) converts the analog interval signal into a digital interval signal. The computer(12) controls the regular current value between electrodes of the metal bond base(1) according to the digital interval signal. The digital to analog converter(11) converts the current value signal from the computer(12) into an analog control signal. This analog control signal controls the automatic controller of regular current(6). Thereby, the optimum electrolytic inprocess dressing is performed and the dressing effect is uniform regardless of process time.
