Abstract
An abrasive surfacing machine is disclosed that is specifically intended to debur and polish hard components (e.g., metal and plastic). The machine includes a horizontal component conveyor with an overlying abrasive surfacing head. The abrasive head has a large disk with a substantially planar abrading surface that is substantially parallel to the workpiece carrying surface of the conveyor. The diameter of the disk is appreciably larger than the width of the conveyor, so that every workpiece will be engaged by the abrasive medium in at least two directions, notwithstanding its position on the conveyor belt. The abrasive medium may be formed from a uniform, lofty, open, non-woven, three-dimensional web of fibrous members, or may be formed from a plurality of bristles impregnated with abrasive particles. The multidirectional abrasive engagement insures complete deburring of each component, notwithstanding its size, and also provides for continuous, uniform dressing of the abrasive medium.
