What Is Fiber Laser Cutting?

Fiber laser cutting focuses a high-energy-density laser beam onto the metal sheet surface, instantaneously melting or vaporizing the material. Assist gas (N₂ or O₂) blows away the molten material, creating a precision cut kerf.

Compared to CO₂ lasers, fiber lasers have a shorter wavelength (1,064nm) and better beam quality. They have much higher absorption on copper and brass — materials CO₂ laser cannot cut — and cut aluminum 3–5× faster.

N₂ vs O₂ Assist Gas Selection

Nitrogen N₂ — Inert Shield

Cut edge has no oxidation (bright silver), ideal for stainless, aluminum, copper, thin carbon steel. Cut surface ready for immediate welding or coating with no cleanup. Downside: higher gas cost, slightly lower speed.

Oxygen O₂ — Exothermic Assist

Oxygen reacts exothermically with carbon steel, increasing cutting speed for thick stock. Cut edge has slight oxidation (yellow-brown) requiring cleanup before welding or coating. Best for carbon steel over 10mm thick.

Cut Quality Grades

Standard Cut

Standard for most daily fabrication work. Suitable for structural parts — no additional processing needed before bending.

Precision Cut

For mating parts and precision hole patterns. Requires optimized nesting and lower cutting speed. ~10% price premium.

Ultra-Precision Cut

Precision instrument components and medical devices. Requires special fine-cut N₂ parameters — confirm at enquiry.

Zero tooling cost advantage

Compared to punch/shear operations, laser cutting needs no stamping dies. DXF → part in hours. Drawing changes are free — perfect for prototypes and rapid design iteration.

By integrating specialized laser processing techniques, Samshion Rapid ensures optimal edge quality and tight tolerances tailored to specific material properties and thicknesses—delivering perfection from the first prototype to full-scale production.

Inert Gas Laser Cutting

Utilizing high-purity Nitrogen as an inert shielding gas, this process effectively expels molten material from the kerf without reacting with the metal. It is the industrial gold standard for achieving oxide-free edges and superior aesthetics. By eliminating the need for secondary deburring or cleaning, our inert gas cutting service ensures your parts are ready for immediate welding or coating.

Laser Flame Cutting

This leverages an exothermic reaction to significantly boost thermal energy during processing. This high-efficiency method is specifically optimized for thick carbon steel and mild steel plates, delivering rapid cutting speeds and robust structural integrity. While producing characteristic sparks and slag, our specialized service ensures consistent performance and cost-effectiveness for heavy-duty industrial components

Laser Cutting Design Guidelines

Minimum Hole Diameter ≥ Material Thickness

Minimum round hole diameter should be ≥ sheet thickness. For 2mm steel, min hole Ø≥2mm. Smaller holes degrade cut quality and risk breakthrough failures.

Hole Spacing & Edge Distance ≥ 2× Thickness

Hole-to-hole and hole-to-edge distances should be ≥2× material thickness to prevent local overheating and distortion during cutting.

Thin Webs Width ≥ 2× Material Thickness

Very narrow ribs (width <2× thickness) will warp from thermal distortion during cutting. Widen or redesign as a bent reinforcement feature.

Replace Sharp Corners with R0.2–0.5mm Radii

Perfect 90° internal corners cause slight over-burn at the apex. Specifying R≥0.2mm internal radii improves cut quality and saves laser lift-travel time.

File Format & Submission Requirements

Preferred Format: DXF (AutoCAD) · STEP (with thickness)
Also Accepted: DWG · AI · PDF · SolidWorks files
Layer Convention: Outer contour/inner holes/bend lines on separate layers
Units: Millimeters (mm), 3 decimal places
Line Width: Cut lines = 0 (hairline), no area fills
Repeated Geometry: Use blocks/groups, do not explode to individual lines
Nesting Gap: Part-to-part spacing ≥2× thickness for efficient nesting

Faster quoting tip

Include material + thickness in the DXF filename (e.g., bracket_steel2mm.dxf) — reduces communication time by 50%.

FAQ

What is the standard precision tolerance for laser cutting?

Samshion Rapid typically achieves industry-leading tolerances between ±0.10 mm and ±0.15 mm. For high-precision requirements, Samshion Rapid utilizes advanced Fiber Laser Fine Cutting to reach an exceptional accuracy of ±0.05 mm on thin-gauge materials. We encourage you to leverage Samshion Rapid’s complimentary DFM review to confirm the tightest possible tolerance for your specific design.

What is the minimum hole size relative to material thickness?

We generally recommend a 1:2 ratio for hole diameter to material thickness to maintain optimal edge quality. However, with high-precision fiber technology, smaller apertures are often achievable. We suggest a quick technical review of your files to confirm the best approach for intricate features.
