Abstract: A method for outer surface finishing of a workpiece may include coaxially placing the workpiece inside a vessel. The exemplary vessel may include at least one baffle that may radially extend from an inner wall of the vessel toward the outer surface of the workpiece. The exemplary method may further include pouring an abrasive medium inside the vessel, rotating the abrasive medium about the longitudinal axis in a first direction within the vessel relative to the outer surface of the workpiece by rotating the vessel about the longitudinal axis, and concurrently rotating the workpiece within the vessel about the longitudinal axis in a second direction, the second direction being opposite the first direction.

Abstract: Disclosed herein is a method for inner surface finishing of a workpiece, in which the inner surface of the workpiece defines an opening with axial symmetry around the longitudinal axis of the workpiece. The method may include the following steps. An abrasive medium may be poured inside the opening; urging the abrasive medium to rotate about the longitudinal axis, thereby imposing a centrifugal force on the abrasive medium to accelerate the abrasive medium outwards from the center of rotation towards the inner surface of the opening, where the abrasive medium impacts the inner surface of the opening; and the workpiece may be rotated about the longitudinal axis in a direction opposite the first direction, concurrently.
