A device for surface finishing of parts may include: an annular container configured to receive working media and at least one part, the container having a central axis and bottom surface; vibratory means associated with the container for causing the container to oscillate, wherein the vibratory means is configured to cause the at least one part to circulate in the container along a path; and at least one projection on the bottom surface and having a crest extending along a respective radial direction, an ascending lateral surface from the bottom surface to the crest, and a descending lateral surface from the crest to the bottom surface. The device may further include a plurality of the projections. The projections may change a spatial orientation of the at least one part as it moves on the projections. The crest may be inclined with respect to the radial direction downwards toward the axis.
