Laser Cutting Service

SUDACNC delivers high-precision fiber laser cutting service for metal sheets and structural tubes. Our high-power CNC fiber laser systems achieve ±0.05mm repeatable tolerance, process intricate complex cutouts, micro holes and fine slits with minimal heat-affected zone and low burr edges. Compatible with carbon steel, stainless steel, aluminum, brass and copper materials, supporting single prototype samples and large nested mass production batches. All laser cut blanks can be directly processed in-house via deburring, bending, welding, sandblasting and powder coating to deliver finished sheet metal assemblies without third-party outsourcing.

What Is Fiber Laser Cutting?

Fiber laser cutting uses a focused high-energy fiber laser beam to instantly melt and blow away metal material via high-pressure auxiliary gas (nitrogen/oxygen), digitally controlled by CNC programs to cut custom 2D outlines and tubular profiles according to CAD drawings.

Compared with waterjet, plasma and guillotine shear cutting, fiber laser delivers the highest dimensional precision, smallest kerf width, fastest cutting speed for thin & medium metal sheets, and the ability to fabricate ultra-fine intricate geometries unachievable by traditional cutting methods. It features tiny heat-affected zones to reduce thermal warpage, minimal post-cut deburring labor, and intelligent nesting software to maximize raw sheet material utilization and lower unit blanking cost for mass orders.

Two Core Laser Cutting Modes: Flat Sheet & Structural Tube Laser Cutting

We operate independent flat sheet fiber laser production lines and dedicated tube laser cutting equipment to cover all 2D blanking and 3D tubular profile cutting demands. CNC fiber laser systems use programmable nitrogen/oxygen auxiliary gas to optimize edge finish for different metals and thicknesses, deliver consistent precision across single prototype samples and large nested mass production batches, with intelligent sheet nesting software to maximize raw material utilization and lower unit blanking cost.

Unique Strengths Of Our In-House Laser Cutting Lines

  • Micro Fine Feature Capability: Minimum 0.1mm internal holes and ultra-narrow slits unachievable by plasma or shear cutting
  • Controlled Minimal HAZ: Tiny heat-affected zone under 0.3mm to avoid thin sheet thermal warpage & deformation
  • Two Auxiliary Gas Options: Nitrogen for smooth dross-free cosmetic edges; oxygen for low-cost thick carbon steel cutting
  • Seamless Downstream Fabrication: Laser cut blanks directly flow to deburring, bending, punching, welding and coating stations without cross-factory transit

Full Metal Materials Compatible With Our Fiber Laser Cutting Service

Highly reflective copper & brass require optimized laser power and nitrogen assist gas to reduce reflection instability; ultra-thin foil parts adopt low-power precise laser parameters to avoid burn-through.

Mild cold rolled / hot rolled carbon steel, galvanized steel, wear-resistant NM400 plate, stainless steel 201, 304, 316L, 430

Carbon steel uses oxygen assist gas for fast low-cost cutting; stainless steel uses high-purity nitrogen to achieve dross-free mirror smooth edges for decorative cabinet panels.

Aluminum 1100, 5052, 6061, 6063, 7075 alloy sheets & hollow tubes

Aluminum high reflectivity requires high-power fiber laser + nitrogen assist gas; thin aluminum sheets strictly control cutting path sequence to minimize thermal warpage.

Pure copper C110, brass C2600 / C36000 bronze thin sheets for signage, conductive contact blanks, decorative hardware

Limited maximum cutting thickness (8~12mm), reserved for thin precision decorative & electrical conductive components only; thick copper alloys recommend waterjet cold cutting.

Material & Thickness Matching Consultation For Laser Cutting Projects

Laser Cutting Auxiliary Gas Options & Full Post-Cut Secondary Treatments

Nitrogen Gas Cutting: High-pressure inert gas blows molten metal away without oxidation, zero dross, smooth silver matte cutting edges, ideal for stainless steel, aluminum, brass cosmetic precision parts; higher gas consumption cost.

Oxygen Gas Cutting: Oxidation reaction accelerates carbon steel melting speed, low operating cost for thick structural carbon steel base plates; cut edge forms dark oxide dross requiring post grinding & deburring.

Automatic tumble deburring machine removes micro laser dross and sharp burrs on all cut edges; rotary edge rounding to R0.5~R2.0mm safe smooth edges for assembly handling, eliminate scratch risk during bending & welding.

Degreasing & oxide cleaning to remove laser melt residue; stainless steel passivation anti-rust treatment; sand blasting uniform matte texture to boost powder coating adhesion for finished painted assemblies.

Critical DFM Design Rules To Avoid Laser Cutting Defects & Rework

2D Drawing Design Feature Laser Cutting Mandatory Design Rule
Internal Hole Minimum Diameter≥1.2 × sheet material thickness; thin stainless can reach 0.1mm micro hole under special parameter
Narrow Slit Minimum Width≥0.15mm minimum; avoid slits thinner than kerf width to prevent material bridging
Inner Sharp CornersAdd minimum R0.1 fillet radius; sharp zero-radius corners create concentrated heat burn marks
Thin Long Rib FeaturesThin ribs below 1.0mm easily warp from thermal heat; add connection tabs during nesting to fix flatness
Material Border MarginReserve ≥0.8× thickness blank margin around all parts to prevent sheet edge cutting instability
Thick Plate Taper ControlPlates over 12mm generate slight beam taper; critical mating surfaces reserve tolerance allowance
