Materials for Jewellery Tumbler Polishers

Jewellery tumbler polishers are mainstays in the jewellery making business. After all, for many hobbyists, there is joy in creating a piece of jewellery from start to finish—from generating your own rocks and gems from raw rocks, to putting them together in a chain for a necklace or bracelet.

Of course, the most obvious part of the jewellery tumbler is the barrel. Regardless of whether you’re using a rotary tumbler, a magnetic tumbler, or even an ultrasonic polisher, you will inevitably encounter a barrel. This barrel is often used to house some parts of water, the rock for tumbling, and the grit that is used to shape, smooth, and polish the rock. Some of these barrels are lined with neoprene rubber to keep it strong against the pressure inherent in the process of tumbling.

Usually, this barrel is attached by a cord to the motor that drives the tumbling action. Obviously, the cord keeps the barrelin place as it rotates on end.

Grit is used because of the fact that the natural collision and friction against grit simulate the environmental pressure that polished, beautiful gems and rocks are subject to over many years. There are usually three sorts of grit used in tumbling. The process begins with coarse grit, which is then replaced with medium grit, then replaced with fine grit. These grits, with the help of the rotating action of the barrel, or the magnetic forces that the barrel is subject to, come in massive collision with the rock, with friction causing shaping and polishing.

For the final polishing stages, a variety of chemicals are used, one of which is Tripoli polish. The others are aluminum oxide, cerium oxide, tin oxide, and chrome oxide. You only have to pick one of these as the final fourth stage after the rock being subjected to grit.

The entire process takes about 3-4 weeks for rotary tumblers, and 7 days or more for magnetic tumblers.
