Precision Sheet Metal Laser Cutting Techspecs

Our facility utilizes advanced, high-wattage CNC Fiber Laser systems engineered for extreme dimensional accuracy, clean edge quality, and rapid processing across diverse material grades.

1. Material Thickness Capabilities

Our laser power scaling allows us to cut everything from ultra-thin shims to heavy industrial plate. Maximum cutting thicknesses depend on the assist gas setup used to optimize edge quality.

Material Type	Max Thickness (mm)	Max Thickness (Inch)	Preferred Assist Gas
Carbon Steel / Mild Steel	20.0 mm	0.78"	Oxygen (O₂) for speed / Nitrogen (N₂) for clean cut
Stainless Steel (304 / 316)	12.0 mm	0.47"	Nitrogen (N₂) – Oxide-free edge
Aluminum (1000 - 6000 Series)	10.0 mm	0.39"	Nitrogen (N₂) or High-Pressure Air
Brass / Copper (Reflective)	5.0 mm	0.20"	High-Pressure Nitrogen (N₂)

Angle: ± 0.1° Kerf: 0.15 - 0.30 mm

3. Design-for-Manufacturing (DFM) Guidelines

To prevent heat distortion, structural warping, or part failure during the thermal cutting process, we recommend engineers adhere to the following baseline rules:

Minimum Hole Diameter

Must be ≥ 1.0 × the material thickness. For example, if cutting 4 mm stainless steel, the minimum hole diameter should be 4 mm to ensure a perfectly round, non-tapered cylinder.

Minimum Feature Spacing

Keep web bridges, slots, and cutouts at least 2 × the material thickness apart to avoid localized heat accumulation zones.

Internal Corner Radii

Sharp 90° internal corners are susceptible to thermal stress. A minimum internal radius equal to the material thickness is recommended where design allows.

💡

Edge & Finishing Note

All parts cut with Nitrogen assist gas feature a pristine, oxide-free edge that is instantly ready for structural welding or powder coating without secondary grinding. Parts are automatically deburred to eliminate sharp dross before final QC inspection.

Strategic Technology Selection: Fiber vs. CO₂ vs. YAG Lasers

At Lingyufab, we don't believe in a one-size-fits-all approach. Achieving cost-efficiency and premium edge quality requires deploying the exact laser wavelength and beam profile suited to your specific material chemistry and gauge thickness. Fiber Laser (~1.06 µm): Our Primary Choice. Best for thin-to-medium metals and highly reflective materials (Aluminum, Brass, Copper). It offers ultra-fast cutting speeds, high energy efficiency, and superior focus on thin electronic chassis. CO₂ Laser (~10.6 µm): Best for thick mild steels and non-metals. Deployed at our facility for ultra-smooth edge finishes on exceptionally thick, heavy-gauge industrial structural plates. YAG / Solid-State (~1.06 µm): Best for micro-cutting and thin shims. Utilized for specialized, high-precision micro-features where heat-affected zones must be kept near zero. Engineering Insight: Fiber lasers feature a wavelength 10x shorter than CO₂. This allows the beam to be absorbed much faster by metals, virtually eliminating the back-reflection danger that traditionally ruined optics when cutting highly reflective copper or brass.

Frequently Asked Questions

Q1: What CAD file extensions do you accept for custom orders?

We primarily utilize .DXF and .DWG files for 2D flat geometric profiles. For full 3D assembly models and folded enclosure analysis, please upload .STEP, .STP, or .IGS file vectors.

Q2: Why does the choice of assist gas matter (Nitrogen vs Oxygen)?

Oxygen cutting utilizes an exothermic reaction to cut thick carbon steels rapidly but leaves a dark oxide layer that must be mechanically sanded down before powder coating. Nitrogen cutting cuts through material strictly via heat, producing a silver, laser-clean, oxide-free profile surface ready for secondary coatings or seamless welding instantly.

Q3: What is your Minimum Order Quantity (MOQ)?

We maintain a Zero-MOQ policy for prototyping stages to support development engineering teams during functional tests. Once approved, we have the mechanical infrastructure to smoothly transition you into structural high-volume production batches.

Q4: How do you prevent heat distortion during the laser cutting process?

We use optimized CNC thermal pathing and advanced nesting logic that distributes heat evenly across the entire workpiece rather than concentrating it in one localized area. Additionally, for intricate features, we implement pulse cutting modes and proper spacing between cutouts to keep the heat-affected zone (HAZ) at an absolute minimum.

Q5: Can your fiber lasers cut highly reflective metals like brass and copper?

Yes. Unlike older CO₂ systems which suffer critical optical damage from reflective beam feedback, our advanced fiber laser wavelengths are absorbed much more efficiently by non-ferrous metals. This enables high-speed, continuous, and damage-free precision cutting for all reflective copper, brass, and premium aluminum alloys.
