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.

Using the Correct Grit Sequence on Your Cabbing Wheels
Another critical aspect of using lapidary wheels effectively is selecting the correct grit sequence for your cabbing wheels. Different grits will remove different amounts of material from your stones and produce different levels of polish. Generally speaking, you’ll want to start with a coarse grit (such as 80-grit) and work your way up through progressively finer grits until you achieve the desired level of polish.
When selecting which grits to use in what order, consider factors such as the hardness of the stone you’re working with and how much material needs to be removed before polishing can begin. Keep in mind that some stones may require additional intermediate steps between coarser and finer grits.
Maintaining Your Wheels for Longevity
To keep your lapidary wheels functioning effectively over time, it’s essential to regularly clean and dress them. Cleaning removes built-up debris from previous grinding sessions that could cause uneven wear patterns or damage over time. Dressing helps restore a smooth, even surface to your wheels and ensures that they remain effective at removing material from your stones.
To clean your wheels, use a soft brush or cloth to wipe away debris. To dress them, hold a dressing stick against the wheel while it’s spinning and allow it to wear down the high spots on the wheel’s surface. Be sure not to apply too much pressure or dress too aggressively, as this can cause uneven wear patterns or damage over time.
Experimenting with Different Wheel Speeds
Finally, don’t be afraid to experiment with different wheel speeds when using lapidary equipment. Different speeds can produce different finishes on your stones, so adjusting your machine’s speed can help you achieve the desired level of polish for each stone you work with.
Keep in mind that higher speeds may generate more heat than lower speeds, which could potentially damage some types of stones. If you’re unsure how a particular stone will react to higher speeds, start at a lower speed and gradually increase until you find the right balance between speed and finish quality.
Utilizing a Drip System While Using Your Cabbing Wheels
Using water while grinding is essential for preventing overheating and prolonging the life of your cabbing wheels. A drip system is an excellent way to ensure that water is consistently applied during grinding sessions without having to manually add water throughout the process.
A drip system consists of tubing connected from a water source that drips onto the stone as it rotates on the cabbing wheel. This keeps both the stone and wheel cool during grinding sessions and helps prevent any heat-related damage from occurring. Using a drip system can also help prolong the life of your cabbing wheels by reducing wear caused by excessive friction between the stone and wheel due to overheating.
