Sheet Metal Laser
Cutting Machine

A 3kW fiber laser cuts carbon steel up to 16mm; a 12kW model handles 35mm; a 30kW machine reaches 60mm thick plate. For stainless steel, reduce expected thickness by approximately 25–30%. Aluminum requires higher power due to reflectivity — a 6kW system typically cuts aluminum up to 16mm. GWEIKE offers laser power options from 500W to 60kW to cover all thickness requirements. For detailed cutting data by material and power level, see our cutting thickness guide.

A 3015 machine has a 3000×1500mm working area and handles standard sheet metal sizes — the most widely used format globally. A 4020 machine has a 4000×2000mm working area for larger plates, typically paired with higher laser power (8kW–60kW) for heavy plate applications in shipbuilding, construction and heavy machinery industries. GWEIKE also offers 6025 and 12025 formats for larger requirements.

Oxygen (O₂) for carbon steel thick plate — faster cutting speed but leaves a slightly oxidized edge. Nitrogen (N₂) for stainless steel, aluminum, and thin carbon steel — prevents oxidation and produces a clean, bright finish. The correct choice depends on material, thickness, and downstream processing requirements such as welding or coating.

Entry-level 1–2kW systems start from approximately $15,000–$25,000. Mid-range 3–6kW machines cost $30,000–$70,000. High-power 10–20kW industrial machines range from $80,000 to $200,000. Ultra-high-power 30–60kW systems such as the LF4020GH start from $150,000+.
