Abstract
An apparatus and method for abrading the surface of objects are disclosed. The apparatus comprises a chamber, an abrasive surface defining a wall of said chamber and drive means for moving the abrasive surface relative to the chamber. In use, the aforementioned relative movement promotes circulation of the objects within the chamber, wherein the chamber is shaped such that regions of flow stagnation of the objects within the chamber are avoided or minimized. Additionally or alternatively, the chamber may be shaped to approximate the peripheral flow path of the objects within the chamber.
