Tumbling machine operators set up and operate tumbling machines, often wet or drie tumbling barrels, designed to remove excess material and burrs of heavy metal workpieces and precious metals and to improve surface appearance, by rotating the metal pieces in a barrel together with grit and potentially water, allowing for the friction between the pieces mutually and with the grit to cause a rounding, smooth effect.
