To achieve the desired results, lapidary artists need to use specialized equipment that can handle the hard materials they work with. One of the most commonly used machines in lapidary work is the cabbing machine.

Cabbing machines are designed to grind and polish stones into cabochons, which are polished stones with a domed top and a flat bottom. These machines consist of a spinning wheel that uses abrasive grits to shape and smooth the stone’s surface. Cabbing machines come in different sizes and configurations, from small hobbyist models to large industrial-grade ones.

To use a cabbing machine, you first need to select the appropriate grit size for your stone’s hardness level. Then, you attach the stone to a dop stick using wax or adhesive putty and place it on the machine’s spinning wheel. As you grind away at the stone’s surface with progressively finer grits, you’ll notice its color and pattern become more vivid.

Flat Laps: Ideal for Grinding Flat Surfaces

Another type of grinding equipment used in lapidary work is flat laps. These machines are designed for grinding and smoothing flat surfaces on stones, such as slabs or tiles. Flat laps consist of a rotating metal plate covered with diamond-impregnated pads that gradually remove material from the stone’s surface.

Flat laps come in different sizes, ranging from small tabletop models to large floor-standing ones used in commercial settings. Some models also have adjustable speed controls so that you can vary the grinding speed depending on your needs.

Using a flat lap is relatively straightforward – you place your stone on top of the rotating plate and apply pressure while moving it back and forth across the surface until it reaches your desired level of smoothness. Flat laps are particularly useful for grinding and polishing large pieces of stone, such as tabletops or countertops.

Diamond Wheels: Ideal for Aggressive Grinding

Lapidary artists often turn to diamond wheels. These wheels use industrial-grade diamonds embedded in a metal matrix to grind away at the stone’s surface quickly. Diamond wheels come in different shapes and sizes, depending on the type of work you’re doing.
