The MT-4 Mini-Sonic tumbler operates with no moving parts—no shafts, belts, pulleys, spinning weight or even a motor—no parts to maintain, wear out or replace. This tumbler converts electric current into vibrations (more than 3,500 vibrations/minute) that power the rotation of the load. The intensity of the vibration is adjustable using solid state electronic controls. While parts tumble, they are alternately separated and pushed together; this cycling allows fresh abrasive to be drawn into and among the jewelry pieces yet leaves the hopper itself practically motionless on your work surface. Compared to other tumblers, the Mini-Sonic requires only a small amount of abrasives; the abrasive breaks down and combines with the water, forming a slurry that is extremely effective.
