Abstract
Barrel polishing is effected while causing a mass (M) consisting of work and media (polishing material) to rotation-flow by rotating a rotary disk installed in the bottom of a polishing tank by a drive motor. A load on the drive motor for the rotary disk is preset as by a load current value, and the flow of the mass (M) in the polishing tank is controlled, thereby effecting polishing while maintaining the load on the drive motor within the preset range.
