Can A CNC Router Cut Metal?

Computer numerical control (CNC) technology has revolutionized the manufacturing industry, providing high-precision and efficient processing for a wide range of materials. When you think of CNC engraving machines, the first thing that comes to mind may be wood engraving, acrylic cutting, or PVC sheet processing. But many users also ask a common question: "Can CNC engraving machines cut metal?" In this article, UTECH takes a deep dive into the capabilities of traditional woodworking CNC engraving machines and explores their potential in the field of metal manufacturing.

1. Can CNC engraving machines cut metals.

Can CNC engraving machines cut metals? The answer is: Yes, but with restrictions. CNC engraving machines can indeed process soft metal materials such as aluminum, copper, brass, etc. in certain configurations, but are not suitable for cutting thick or hard metals such as carbon steel, stainless steel or alloy steel.

What metal materials can CNC engraving machines cut?

• Aluminum: Aluminum is a popular choice because it is relatively soft compared to other metals and is widely used in industrial applications. With the right settings, CNC engraving machines can effectively cut and engrave aluminum, making it ideal for prototypes and custom parts.

• Brass and copper: Brass and copper are also viable options. These metals are softer and more ductile, but are prone to burrs and require careful consideration of cutting parameters to obtain clean edges.

2. Factors that determine the metal cutting ability of CNC engraving machines

The main factors that determine whether a CNC milling machine can cut metal are the power, rigidity of the machine tool, and the type of metal being processed. Metal is generally harder and denser than wood or plastic, so more robust equipment and suitable cutting tools are required.

Machine tool rigidity and design

Cutting metal requires a CNC milling machine with a sturdy frame and gantry to withstand the forces applied during the cutting process. Machine tools designed for metal processing usually have a reinforced structure to minimize vibration, which can affect accuracy and tool life.

Spindle power and speed

Metal cutting requires higher spindle power to maintain efficiency and quality. CNC milling machines that can cut metals such as aluminum or brass are usually equipped with spindles that can provide higher torque at lower speeds. This adjustment ensures sufficient cutting force without overheating the material or tool.

Cutting tools and tooling

Choosing the right cutting tool is essential. Carbide or diamond-coated end mills are commonly used in metalworking due to their hardness and durability. To optimize chip evacuation and reduce tool wear, tool geometry, including the number of flutes and helix angle, must be considered.

3. What scenarios are suitable for cutting metal with a CNC engraving machine?

If you are a user with the following needs, then the CNC engraving machine is still an economical and practical choice for metal processing:

• Small batch non-ferrous metal parts proofing or cutting

• Engraving metal nameplates, LOGO plates or aluminum panels

• Teaching or laboratory projects

• Furniture decoration, wood + metal splicing applications

• DIY mechanical parts, model making

4. Metal cutting safety operation suggestions

• Use protective glasses and turn on the dust removal system

• Never overspeed the spindle, set it reasonably according to the tool specifications

• Use a fixture or vacuum platform to stabilize the material

• Real-time monitoring of equipment temperature and tool vibration

• After processing, clean the coolant and metal chips to extend the life of the equipment

In summary, CNC engraving machines can cut metals, especially softer metals such as aluminum, brass, and copper, but they need to be moderately and properly configured. Although CNC engraving machines cannot directly replace CNC milling machines in heavy metal processing, they provide versatility for specific applications that require cutting wood and metal. With the support of the correct settings, tools and cooling systems, CNC engraving machines can efficiently cut or engrave soft metal materials, which is very suitable for lightweight processing, creative projects or low-cost metal processing needs. But if you need to cut thick metal plates, high-strength materials or large-scale industrial production, it is recommended to choose fiber laser or plasma cutting machines as a better solution.
