In one embodiment, a vibration barrel polishing method using a vibration barrel polishing system that includes a polishing tank having a bottom surface therein and a polishing jig capable of holding a workpiece and rotatable around a rotation axis is provided. This method includes a step of supporting the polishing jig in the polishing tank in a state in which a lowermost portion of the polishing jig is separated from the bottom surface, a clearance d between the lowermost portion of the polishing jig and the bottom surface being greater than or equal to a grain diameter of a polishing medium, a step of causing the polishing medium to flow in the polishing tank, and a step of rotating the polishing jig around the rotation axis in the state in which the lowermost portion of the polishing jig is separated from the bottom surface.

A method for the surface finishing of workpieces moves the workpiece, including rotating about at least one axis, relative to a bed of a granular grinding and/or polishing material. The workpiece is accelerated to different speeds of rotation in relation to the bed of the granular grinding/polishing material. The workpiece or a container containing the bed of granular grinding/polishing material to be accelerated in periodic cycles of at most 5 sec between speeds of rotation and a second speed of rotation and/or to be rotated during continual acceleration at continually different speeds of rotation. A device for carrying out the method, such as a drag- or dip-finishing machine, includes a control device to impose speed of rotation profiles of the aforementioned type on a rotary drive workpiece holders, on which the workpieces can be clamped, or on a container containing the bed of granular material during the operation.
