A cabbing machine is a piece of lapidary equipment specifically designed for shaping and polishing gemstones into cabochons. It is a specialized tool used by lapidaries, jewelers, and gemstone enthusiasts to create smoothly rounded, convex top gemstones with a flat or slightly domed base.
A typical cabbing machine consists of the following components:
Grinding Wheels: Cabbing machines are equipped with grinding wheels that come in various sizes and grits. These wheels are made of abrasive materials, such as diamond or silicon carbide, and are used to shape the gemstone by removing excess material.
Water Cooling System: Many cabbing machines have a water cooling system to prevent overheating during the grinding process. Water is continuously sprayed onto the grinding wheels to lubricate them and keep the gemstone cool.
Motor and Drive System: Cabbing machines are powered by an electric motor that rotates the grinding wheels at a controlled speed. The motor is connected to a drive system that ensures smooth and consistent rotation.
Adjustable Platform: The gemstone being worked on is placed on an adjustable platform that allows the lapidary to control the angle and position of the stone in relation to the grinding wheels. This enables precise shaping and control over the cabochon's symmetry.
Polishing Wheels: Cabbing machines also include polishing wheels or pads made of materials such as felt or leather. These wheels are used in the final stages of the cabbing process to achieve a high polish on the gemstone's surface.
Splash Guard: A cabbing machine may have a built-in splash guard or shield to contain water and debris during the grinding and polishing process. This helps keep the workspace clean and minimizes the risk of injury from flying particles.
Cabbing machines offer a controlled and efficient way to shape and polish gemstones, ensuring consistent results and professional-quality cabochons. They are widely used by lapidaries and jewelry makers to create cabochons for use in various applications, including jewelry, decorative objects, and collectibles.
