Abstract: A method useful for polishing a large number of miniature components such as multi-layer electronic components, within a high speed barrel polishing device, is disclosed. In various embodiments of the present invention, a vertical planetary ball mill or other barrel polishing device is modified to rotate polishing containers having a modified interior cavity structure. This interior cavity provides a smooth, gradually curved interior sidewall that improves circulation within the container during high-speed vertical polishing rotation. The improved circulation results in polishing for a larger number of components placed within the container and in less time than existing polishing container structures. In further embodiments, the containers are rotated around a generally tilted axis positioned at an angle between entirely vertical and horizontal positions. Rotation about a tilted axis further reduces collisions and increases relative polishing movement within the container.
