Yes, CNC machines can cut metal with high precision and efficiency, making them a staple in industries like aerospace, automotive, and prototyping. However, success depends on the machine type, material, and setup— not all CNCs are equally capable.

1.Machine Types: CNC mills (vertical or horizontal) excel at metal due to rigid frames and powerful spindles, handling everything from aluminum to titanium. CNC routers can cut softer metals like aluminum or thin steel sheets but may struggle with harder alloys without upgrades like high-torque spindles or plasma attachments. Plasma CNC cutters are specialized for thicker conductive metals (e.g., steel up to 1 inch).

2.Materials: Softer metals like aluminum and brass cut easily; tougher ones like stainless steel or titanium require slower feeds, robust tooling, and coolant to prevent tool wear or heat distortion.

3.Tools and Settings: Use carbide or high-speed steel (HSS) end mills with coatings (e.g., TiAlN) for durability. Run at lower speeds (e.g., 500–2,000 RPM for steel) with moderate feeds, and always employ flood coolant or mist to manage chips and heat.

4.Limitations: Desktop or hobbyist CNCs (e.g., under 2HP) may only handle thin sheets; industrial models are needed for heavy-duty work. Poor fixturing can cause vibrations, leading to inaccurate cuts.
