What is the cutting thickness by 3000W Fiber Laser Cutting machine

A  3000W fiber laser cutting machine sits at the ideal balance point between cutting performance, cost efficiency, and operational stability. Across metal fabrication, automotive parts production, signage, HVAC, and general manufacturing, 3000W systems are widely recognized for their high precision, clean edges, and outstanding energy efficiency. As a leading laser-equipment manufacturer, Remcor Technology continues to optimize fiber laser cutting solutions to deliver superior cutting depth, speed, and quality for a wide range of materials.

This above cutting parameters provides a professional breakdown of the cutting thickness capabilities of a 3000W fiber laser cutting machine, as well as the factors influencing cutting depth and the optimal parameter settings for best performance.

Cutting Thickness for Steel and Aluminum

Carbon Steel (Mild Steel)

A fiber laser 3000w provides a strong and concentrated beam suitable for clean cutting of carbon steel.

Max cutting thickness (with oxygen): 20–22 mm 

Recommended high-quality cut: 1-10mm

Oxygen serves as an assist gas, allowing for deeper penetration but creating slightly more oxidation on the edge. The cut remains structurally solid and suitable for most industrial applications.

Aluminum (Aluminum Alloy)

Aluminum reflects more laser energy and has high thermal conductivity, which typically reduces achievable thickness, but 3000W systems still perform excellently.

Max cutting thickness (with nitrogen): 6–8 mm

Recommended high-quality cut: 1–4 mm

Nitrogen ensures a bright, oxide-free edge, ideal for precision fabrication, aerospace components, and decorative aluminum panels.

Cutting Thickness for Stainless Steel

Stainless steel responds extremely well to fiber laser cutting due to its lower reflectivity and better absorption characteristics.

Max cutting thickness (with nitrogen): 8–10 mm

Recommended high-precision cut: 1–4mm

A 3000W fiber laser cutting machine running with nitrogen produces a smooth, non-oxidized, burr-free edge. This level of quality is widely appreciated in food-processing equipment, medical device frames, architecture, and high-finish metal parts.

 Cutting Capabilities for Other Common Materials

Brass

Max cutting thickness: 3–4 mm
Brass is reflective, but modern fiber laser sources with anti-reflection protection—such as those used in Remcor Technology machines—enable stable and precise cutting.

Copper

Max cutting thickness: 2–3 mm
Copper’s reflectivity and thermal conductivity limit thickness, but fiber lasers still produce clean contours for busbars, electrical components, and precision parts.

Galvanized Steel

Max cutting thickness: 10–12 mm
Nitrogen or air can be used depending on edge-quality requirements.

Acrylic and Plastics (Optional)

Fiber lasers are not recommended for most non-metallic materials. CO₂ systems are usually more appropriate. However, some engineered plastics can be processed in special cases.

Factors Affecting Cutting Depth

Several technical parameters and environmental conditions influence the real-world cutting thickness of a 3000W fiber laser cutting system:

1. Assist Gas Type and Purity

Oxygen increases penetration but leaves oxide edges.

Nitrogen delivers high-quality, oxidation-free edges but requires higher gas pressure.

Air is cost-effective for medium-thickness cuts.

2. Beam Quality and Laser Source Efficiency

Machines designed by Remcor Technology use high-stability fiber laser generators, ensuring consistent beam quality and deeper, cleaner cuts.

3. Nozzle Size and Gas Pressure

Correct nozzle selection and stable gas flow are essential for cutting thicker metals.

4. Focus Position and Optical Components

The focal point must be precisely adjusted to maximize energy density at the material surface.

5. Material Surface Condition

Rust, oil, and coatings may affect cut depth and edge quality.

6. Cutting Speed

Slower speeds increase penetration but may reduce edge finish if too slow.

Optimal Settings for a 3000W Fiber Laser Cutting Machine

For Carbon Steel (≤10 mm)

Assist Gas: Oxygen

Gas Pressure: 0.5–1.0 bar

Best Practice: Increase pierce time and optimize focus for smoother edges.

For Stainless Steel (6–10 mm)

Assist Gas: Nitrogen (99.999% purity recommended)

Gas Pressure: 12–18 bar

Best Practice: Use a small-focus spot for high-precision, burr-free edges.

For Aluminum (4–6 mm)

Assist Gas: Nitrogen

Gas Pressure: 15–20 bar

Best Practice: Keep cutting speed stable and avoid excessive heat input.

For Brass and Copper

Assist Gas: High-pressure nitrogen

Use anti-reflection protection to protect the laser source.

The CNC cutting software and real-time monitoring systems used by Remcor Technology help operators automatically maintain the optimal settings for thickness, material type, and cutting speed.
