Minisonic MT4 tumbler.
The MT-4SV Mini-Sonic is arguably the best all-round tumbler on the market when considering performance, easy operation and long-lasting and trouble-free service. Bigger capacity than the smaller KG-1 model with a 4 pound load capacity (about 1.75 kilograms).
These types of machines have a unique tumbling action which is both fast and gentle – faster than a rotary tumbler but very gentle so that items can be polished without changing the shape.
The MT-4 operates with any moving parts (shafts, belts, pulleys, eccentric weights or drive motors) so that service life is far longer than other types of tumblers. Electrical power is used to generate more than 3,500 vibrations per minute within the hopper. This model features an electronic controller to adjust the rotation and intensity of the tumbler operation. This model is 240 Volt to suit the Australian power supply.
