Gemstone cutting machine

Types of Gemstone Cutting Machines

A gemstone cutting machine is designed for effective and precise cutting of gemstones, and there are different types, each catering to different needs and levels of expertise. Below are the most popular ones, detailing the operations they perform.

• Lapidary Wheel

  The Lapidary wheel is referred to as the Lap wheel. This machine is commonly used in professional and commercial settings because of its ability to provide fine precision when producing gemstones in large quantities. The operation involves using a rotating wheel embedded with diamond grits at different levels of coarseness. The stone is mounted on a pedestal, and the user will guide it toward the rotating wheel. Each wheel removes hard stone materials, gradually shaping the rough stone into the desired gemstone form. Before polishing, users generally accompany the grinding and shaping processes with the coarser wheels. The wheels with finer grits conduct the polishing process to smoothen the surface and give a shiny finish to the stone. Due to its productive nature, the machine is widely used in mineral business Lapidary.

• Gemstone Faceting Machine

  The faceted stone is also known as a facet cut stone. This is a very important tool, especially for professionals and those with advanced skills. The machine makes a faceted cut by cutting flat, polished facets on a gemstone to create a faceted finish. The operation involves a wheel or lap that cuts the stone while spinning it to give it a faceted shape. This process is used mainly on quartz and diamond. Since faceting machines are built for precise cuts, they help in maximizing the gem's light refractivity, which enhances its brilliance and sparkle. The cutting process creates clean and sharp facets on the stone, which helps lift its aesthetic value and overall quality. Because faceting can be such a precise business, only skilled lapidarists or jewelers generally carry out this kind of cutting.

• Gem Cutting Saw

  A gemstone cutting saw is required for straight cuts in hard materials of different varieties, including minerals. Most of these cuts are used to split larger raw gemstones into smaller manageable sizes for other cutting processes, such as lapidary or faceting. The main purpose of this cutting saw is to provide rough and even splits, but it does have the added benefit of making precise angled cuts, which are sometimes necessary for specific designs. Gem cutting saws use various blades. While some blades are made of regular steel, others are more efficient at cutting diamonds and hard minerals, such as blades coated with extremum. Some saws also use wet cutting, which reduces excessive heat on the blade and minimizes stone dust and shavings.

• Portable Gemstone Cutting Machine

  Due to its convenience, portable gemstone cutting machines are especially useful for novices or craftsmen working in more mobile, informal, and gross settings. A Portable gemstone cutting machine is a compact lapidary setup that could be a diamond saw, a faceting machine, or even a combination of both. What makes them portable is their small, normally lightweight design, which allows for easier handling and transportation. They are powered by either electricity or batteries. It is important to note that their reduced size comes with the limitation of reduced capacity. However, portable machines allow efficient and effective gemstone cutting in small batches or for personal use. They are quite functionally versatile, allowing users to smoothly switch tasks between cutting, sanding, and polishing.

Design of Gemstone Cutting Machine

The design of an automatic gemstone cutting machine has to be very precise to give promising effective results. Below are significant structural features of such machines.

• Cutting Wheels

  Cutting wheels in lapidary machines are made with a bonding ingredient that is, a hard work material embedded within the wheel's surface, mostly diamond particles. The wheels are different in grits, which range from coarse to fine. The coarse wheels have larger grit size, which is used for initial cuts like shaping and grinding. The fine grit wheels are used for polishing, delivering a smooth and glossy finish. The cutting wheels are driven by powerful electric motors that rotate at incredibly high speed.

• Polishing Paddles

  Polishing paddles are similar to cutting wheels in function and design. But unlike cutting wheels, polishing paddles use a softer material on their surface to hold polish freely. Polishing paddles are used to perform the final polishing of the already cut gemstones. Polishing paddles are operated in conjunction with polishing materials and compounds. They also rotate on electric motors at high speeds, similar to the gem-cutting wheels.

• Coolant System

  Coolant systems are essential components of gemstone cutting machines, especially those that perform intensive cutting jobs. One of the most effective cooling methods is using water streams directed onto the gemstone blade or wheel. This method helps wash the gemstones cut debris and even gemstones dust, which can be a health hazard upon being airborne. Coolant systems also contribute to gemstone cutting machines' overall lifespan, durability, and reliability.

• Frames

  Frames of gemstone cutting machines are normally designed with rugged steel frames and protective metal covers because these machines operate in very challenging conditions. The strong frames hold and mount all the parts of the machine together; hence, they are built to absorb any strong cutting vibrations. Frames are designed with enclosures intended to contain and trap unwelcome stones dust as well as noise.

Specification & Maintenance of Gemstone Cutting Machine

Several specifications, such as wheel speed and motor power, determine the performance of a gemstone cutting machine. Regular maintenance helps avoid breakdowns and achieve optimal performance.

• Technical Specs

  Some of the most vital specifications that judge or determine the performance of gemstone cutting machines include wheel speed (RPM), motor power (HP), and blade size. For instance, machines with high RPMs produce a smooth cut, while machines with large blade size cut quickly and efficiently. Also, machines with high HP are more powerful and effective. In terms of specifications, lapidary machines should be operated within a maximum gemstone cutting range to avoid machine damage and produce low-quality cuts.

• Regular Inspection

  This is among the first steps to guarantee long-term and effective performances. Before each cutting session, lapidarists should check for any sign of damage in cutting wheels, blades, motors, and other mechanical parts. Also, they should tighten loose belts and replace worn wheels or blades. When worn wheels or blades are used, they lead to ineffective cuts and overworking the machine.

• Lubrication

  The best method to reduce abrasion and friction among the moving parts of the machine is to properly lubricate the moving parts. Lubrication does not only avoid machine breakdown but enables it to perform gemstone cuts effectively.

• Cleaning

  Debris and dust can significantly affect machine performance. It is important to clean its parts after every cutting session. Special attention should be given to fans, dust filter, wheels, and other components that are likely to accumulate dust and debris. Cleaning machines helps machine longevity and maximizes cutting accuracy.

• Storage

  It is important that gemstone cutting machines be stored properly after use so that they aren't damaged when not in use. It is vital to keep machines in a dry and safe space where they are not likely exposed to humidity or external temperatures. Furthermore, covering machines in protective cases reduce the chances of them being accidentally damaged and help keep enclosures clean.

Scenarios of Gemstone Cutting Machine

A gemstone cutting machine is used in many situations. From making beautiful jewelry to selling greater cut stones, the machines play a very crucial role in the gemstones and minerals industry.
