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.

A method for outer-surface finishing of a workpiece, the method comprising:
- coaxially placing the workpiece inside a vessel, the vessel comprising at least one baffle radially extending from an inner wall of the vessel toward the outer surface of the workpiece;
- 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 opposite the first direction.
An apparatus for outer-surface finishing of a workpiece, the apparatus comprising:
- a vessel comprising at least one baffle radially extending from an inner wall of the vessel toward the outer surface of the workpiece, the vessel further configured to contain an abrasive medium poured between the inner wall of the vessel and the outer surface of the workpiece;
- a first rotary actuator coupled to the vessel and configured to drive a rotational movement of the vessel about the longitudinal axis of the workpiece in a first direction, the at least one baffle within the vessel configured to push the abrasive medium to assume a rotational movement around the longitudinal axis of the workpiece;
- and
- a second rotary actuator coupled to the workpiece and configured to drive a rotational movement of the workpiece within the vessel about the longitudinal axis of the workpiece in a second direction, the second direction opposite the first direction.
