Tumbling

Tumbling is a finishing operation often required following the die casting of the parts. The purpose of the tumbling process is to remove what is commonly called "burr", or the residues of the metal substrate.

The term tumbling comes from the name "tumbler", barrel, which is actually the equipment dedicated to this surface finish: the parts, usually in a large number and small in size, are placed inside a vibrating and rotating barrel, often along with other abrasive material to accelerate the results. In some cases, for burnishing, special cleanings or chemical treatments of the pieces, water, lubricants, detergents or chemical solutions are added within the special barrel.
