Abstract
A barrel polishing machine includes an electrically conductive inner container for containing workpieces, the inner container having a number of holes formed in a circumferential wall thereof so that an electrolyte supplied to the workpieces passes through the holes, an electrically conductive outer container disposed to surround the inner container with a predetermined gap between them, a pair of electrode terminals connected to the inner and outer containers respectively so that the containers serve as electrodes with polarity opposite each other, respectively, an insulator interposed between the inner and outer containers with a predetermined gap between the same and each container, and a drive source supplying a rotational or vibratory force to the inner container. The gap between the inner and outer containers is 10 millimeters long or below. The barrel polishing machine may be diverted to an electroplating machine when the polarity is inverted.
