Burnishing, deburring and tumbling are specific applications that fall under the broad term mass finishing. Mass finishing refers to a varied group of surface conditioning processes used in manufacturing operations. Cleaning and polishing are also examples of surface conditioning applications. Typically each mass finishing process requires a different media and compound or fluid.
Burnishing is done to produce a highly reflective finish on the parts surface. The burnishing process involves smoothing the surface peaks into the valleys. Non-abrasive sintered bauxite or metal media are often used for this operation.
Deburring is the process of removing burrs. Burrs are the undesirable sharp edges or protrusions on a parts surface produced during the manufacturing process. Parts are deburred by tumbling the parts in a barrel or a vibratory bowl, along with finishing media.
