Mass finishing, also known as vibratory finishing, is a manufacturing process used to deburr, polish, clean, or smooth large quantities of small to medium-sized parts.

This technique involves placing parts into a vibrating or tumbling machine filled with abrasive media and often a cleaning or polishing compound. As the machine vibrates, the media and parts rub against each other, gradually refining the surface of the components. It’s widely used in industries such as automotive, aerospace, and metalworking to improve surface finish, remove sharp edges, or prepare parts for coating or assembly. The process is highly efficient, cost-effective, and ideal for treating batches of parts uniformly.
