PURPOSE:To enable simultaneous and uniform electrolytic polishing of a number of works, by a method wherein each of a number of the output terminals of a pulse source is connected to each feeder pressurizing part, and a number of electrodes, on which pulses generated at given intervals are orderly applied, is protruded from the upper surface of a electrolyte feed box. CONSTITUTION:Each of works 30 is set around each of electrodes 4, and a feeder pressurizing part 11 is lowered by a feeder pressurizing cylinder 12 to clamp the work 30. With this state, a circulating pump 8 is run, and pulse currents are orderly applied to the electrodes 4 through the respective feeder pressurizing parts 11, each connected to an output terminal, by means of a pulse source 16 in a state that an electrolyte flows through a gap between the electrode 4 and the work 30 from the interior of an electrolyte feed box 2. Since electrolytic polishing by a pulse current stabilizes a system during a rest of a current, extremely high current density can be provided, and a number of the work 30 set around their respective electrodes 4 are high- efficiently and simultaneously electrolytically polished by means of pulse currents being orderly applied.
