Stone Cutting CNC Routers – What Can They Cut

Introduction to Stone Cutting CNC Routers

The world of manufacturing and woodworking has been revolutionised by Computer Numerical Control (CNC) technology. But did you know this powerful technology isn’t limited to just wood? CNC routers can cut a broad range of materials, including a variety of stones. Before we delve into what these mighty machines can do, let’s take a brief look at their history.

The History and Evolution of CNC Routers

CNC technology has roots dating back to the 1940s, with the advent of “Numerical Control” machines. These machines, driven by the punch-card system, were the predecessors of modern CNC routers. As technology advanced, so did these machines, eventually evolving into the sophisticated CNC routers we see today.

What is a CNC Router?

A CNC router is a computer-controlled cutting machine related to the hand-held router used for cutting various hard materials. They’re the go-to machines for many manufacturing and woodworking tasks.

Features and Components of a CNC Router

A CNC router’s main parts include a dedicated software system, a controller (alongside its drives), a cutting table, and a router spindle, alongside the coolant to ensure the longevity of your tooling.

Software: The Brains of CNC Routers

Software is the brains of the operation, responsible for translating a digital design into physical coordinates for the machine to follow. The most common types are CAD (Computer-Aided Design) and CAM (Computer-Aided Manufacturing) software. All of our Stone CNC Routers come complete with Vectric V Carve Pro.

Router (Spindle): The Heart of CNC Routers

The router, or spindle, is the heart of the machine. It’s the part that does the actual cutting, spinning the cutting tool at high speeds to cut through the material.

The Types of Materials Stone CNC Routers Can Cut

While CNC routers are famous for cutting wood and metals, they can also effectively cut stone materials, which we will explore next. Our Stonetech Stone CNC Routers are specifically designed to process stone materials rather than wood, especially with the addition of a constant flow of water to cool tooling, that is then cycled back through the machine.

Stone Materials: A Closer Look

Various types of stones can be cut using Stone CNC routers. These include but are not limited to marble, granite, limestone, sandstone and slate. Let’s take a closer look.


Marble is a soft stone that’s easily carved and engraved using CNC routers. It’s an excellent choice for intricate designs.


Granite is a harder stone and requires more power to cut. However, with the right CNC router and cutting tool, even intricate designs are possible.


Limestone, like marble, is relatively soft and can be cut using a CNC router. It’s often used for decorative features and wall claddings.


Sandstone is another stone that can be easily cut with a CNC router, making it ideal for a variety of decorative uses.


Slate, known for its fine grain and hardness, is frequently used in flooring, roofing, and flagging. A CNC router can cut and carve slate precisely, making it an invaluable tool for craftsmen and builders alike.

Advantages of Stone Cutting CNC Routers

CNC routers offer numerous benefits when it comes to cutting stone, including precision, efficiency, versatility, and safety.

Precision and Efficiency

CNC routers can cut stone with high precision and speed, significantly reducing production time.


These machines can handle a wide range of designs, from simple cuts to intricate details, offering incredible versatility.


CNC routers are safer than manual cutting methods, as the cutting is entirely machine-operated, reducing the risk of accidents, always follow the correct training and guidance from your machinery supplier and adhere to local safety laws.


Stone cutting CNC routers are a versatile and efficient tool in the manufacturing and woodworking industry. With the ability to cut a variety of stones with high precision and safety, these machines are a game-changer. Whether you’re cutting marble, granite, limestone, or sandstone, the right CNC router can make the job more manageable.


What is the primary function of a CNC router?

The primary function of a CNC router is to cut various materials like wood, metal, and stone into specific shapes based on the design input into the software.

Can Stone CNC Routers cut all types of stone?

While CNC routers can cut many types of stone, the hardness of the stone and the type of cutting tool used can influence the cutting process. It’s always best to confirm your application with a qualified CNC router supplier and do tests to ensure machine suitability.

Are Stone CNC Routers safe to use?

Yes, CNC routers are generally safe as the cutting is machine-operated. However, users should follow safety guidelines and wear protective equipment when operating these machines.

What factors should I consider when choosing a CNC router for stone cutting?

Consider the type and hardness of the stone you’ll be cutting, the size of your projects, and your budget.

Can I use a CNC router for intricate designs on stone?

Yes, CNC routers can handle intricate designs, making them ideal for detailed work on stone materials.
