Browse CNC machines by the material they cut

CNC machines are highly versatile and can cut a range of materials, including:

• Acrylic
• Aluminium
• Carbon Fibre
• Cardboard
• Composite
• Fabric
• Foam
• Leather
• MDF
• Metal
• Paper
• Plastic
• Plywood
• Stainless Steel
• Textiles
• Titanium
• Wood

CNC machines maintain quality by adjusting parameters and tool settings specific to each material. Here’s how:

• Bit or tool selection: CNC routers and knife cutters use specialised bits and blades designed for different materials. For instance, carbide bits are often used on wood and plastics for a clean cut, while softer metals might require bits designed to withstand higher temperatures and provide smooth finishing. In laser cutters, no physical tool touches the material; instead, power levels and laser focus are adjusted based on the thickness and hardness of the material.
• Power and speed adjustments: Each material requires unique cutting speeds, feed rates, and power settings. For example, laser cutters use low power and higher speed on paper to prevent burning, while metal cutting requires slower speed and higher power for precise cuts. Adjusting these settings optimises quality and ensures a smooth finish without charring, warping, or tearing.
• Cooling systems: For materials like metal, CNC machines often integrate cooling systems, such as compressed air or liquid coolants, to maintain quality by preventing heat-related damage and prolonging tool life.
• Material-specific techniques: Techniques like step-down depth adjustment in routers (to prevent chipping in wood) or air-assist systems in laser cutters (to reduce burning on thin materials) help ensure the material is processed optimally. These material-specific adjustments help achieve the desired precision, finish, and durability.
