The Final Guide to CNC Laser Metal Cutting: Accuracy of Speed of Light
In the dynamic world of modern manufacturing, it is crucial to effectively achieve complex, high-precision metal parts. CNC (Computer Numerical Control) laser cutting has become a cornerstone technology, which has completely changed the design and production methods of the industry. At Greatlight, as an expert in advanced five-axis CNC machining and manufacturing, we utilize state-of-the-art laser cutting technology every day. This guide delves into the process, its benefits and why it is often the best solution for custom metal parts.
Learn about CNC laser metal cutting: Beyond Spark
CNC laser cutting is a subtraction manufacturing process. It uses a highly focused high-power laser beam (generated by carbon dioxide, fibers or increasingly disk lasers) to melt, evaporate or burn material from metal plates or plates. The beam path, strength, speed and airflow are all precisely controlled by a computer program. The program is derived directly from your digital CAD or CAM drawings to ensure excellent accuracy and repeatability.
Think of it as a scalpel that concentrates energy. The laser head is guided by a CNC system and tracks the programmed profile with incredible speed and accuracy, resulting in clean, complex cutting, and minimal material distortion.
Unrivaled Advantages of CNC Laser Cutting
Why does laser cutting become so dominant? Its advantages are convincing:
- Excellent accuracy and accuracy: Tolerance reduction to tenths of a millimeter (±0.1mm or higher) is usually achievable, ideal for complex geometries and tight fittings.
- High-quality quality: Laser cutting produces smooth, burr-free edges with high-quality finishing, which often eliminates or significantly reduces the need for secondary finishing processes.
- High speed and efficiency: The laser cuts thin to medium thick metal very quickly. Since the tool path is digital, cutting complex shapes is as fast as simple shapes.
- Minimum Material Waste (Notch): The laser beam is unusually narrow (KERF width is typically 0.1 mm to 0.3 mm), which maximizes material utilization and reduces waste costs, especially on nestable parts.
- Versatility of material and thickness: From stainless steel, carbon steel and aluminum to copper, brass, titanium and a wide range of alloys, lasers can handle a wide range. While the best suited for thin to medium sheets/thickness (usually 25mm of steel, smaller/lower conductivity metals) is still moving forward.
- Non-contact process: Since the laser beam has no physical contact with the material, there is no tool wear (reducing ongoing tool costs) and no mechanical pressure or contamination on the workpiece.
- Automation and consistency: Laser cutting is seamlessly integrated into the CNC workflow, ideal for mass production runs, ensuring that each part is the same as the first part.
Materials mastered with laser beams
CNC laser cutting comes with various metals. Here is a snapshot of common material we specialize in on Greatlight:
- Carbon steel: (Low to high strength): Including low carbon steel. Excellent cutting quality, perfect for structural parts, chassis, housing. Effectively handle huge thickness.
- Stainless steel: (Grade 304, 316): Production of clean, non-oxidized cutting is crucial for medical equipment, food processing equipment and building elements.
- Aluminum and alloys: Although reflective and conductive (modern fiber lasers overcome challenges), aluminum is widely used in aerospace, automotive and electronic devices due to its lightweight properties.
- Copper and Brass: A good conductor of heat and electricity requires specific laser parameters. Used for electrical components, decorative components and heat exchangers.
- titanium: High strength to weight ratio, biocompatible. It is crucial for aerospace and medical implants. A controlled atmosphere (usually an inert gas) is required during the cutting process.
- Professional alloys: Like Inconel, Hastelloy, etc., are often used in extreme environments (aerospace, energy). Cutting parameters require precise expertise.
The specific cutting quality, the thickness that can be achieved, and the auxiliary gas (oxygen, nitrogen or air) required depends largely on the material properties. It is crucial here to work with experienced partners like Greatlight.

FAQ: Your CNC laser cutting question has been answered
Q1: What is the maximum thickness of metal that your laser cutting machine can handle?
A1: Functions based on metal type and laser power vary greatly. Usually, we are good at:
- Carbon steel: up to 25-30mm (common structural metals)
- Stainless steel: up to 20-25mm
- Aluminum: up to 15-20mm
- Copper/brass: Usually thinner section, up to 8-12mm.
For projects requiring thicker materials, we generally recommend strategies that combine laser spectroscopy with multi-axis milling capabilities. Please contact you for your specific material and thickness requirements.
Q2: How thin are the details, or how small are your laser cutting?
A2: The laser cutting is excellent. The minimum feature size depends on the material thickness and type. As a general guide:
- The minimum pore diameter that can be achieved is approximately equal to or greater than the material thickness.
- Conventional complex profiles and small internal features (±0.1mm or higher) are conventional.
Our advanced laser and software optimizations allow us to push these boundaries effectively.
Q3: What file format do I need to provide for laser cutting?
A3: We prefer industry standard vector formats that define precise paths and clippings:
- DXF (Drawing Interchange Format) – Most common and universal.
- DWG (AutoCAD picture)
- AI (Adobe Illustrator)
- Steps/Iges – Especially when used in combination with 3D functions.
The high resolution CAD format ensures that your design is most accurate for translation into a cutting program. Our engineers can guide you.
Q4: Is laser cutting necessary? What are the choices?
A4: While laser cutting creates clean edges, the finish enhances functionality and appearance:
- Smooth edges/hair removal: Often rare, but sometimes critical edges are required.
- clean: Use processes such as passivation (stainless steel) to remove oxides (proportion) or soot.
- Grinding/processing: To achieve a specific critical tolerance or flatness of the cutting edge.
- Surface finish: Powder coating, painting, anodizing (aluminum), electroplating, polishing.
