Overview
Our heavy steel plate laser cutting service delivers precise, burr-free cuts for thick materials used in wind towers, machinery, and infrastructure. Leveraging 20kW fiber laser technology, we process plates up to 150mm thickness with micron-level accuracy, ideal for complex geometries and high-volume production.
Features
Cutting Precision
Positioning accuracy: ±0.05mm (for thickness ≤50mm), ±0.1mm (50mm-150mm), confirmed by coordinate measuring machine (CMM) inspections.
Bevel cutting capability (0°-45°) for direct weld preparation, reducing secondary processing time by 60%.
Material Capability
Processable materials: carbon steel (up to 150mm), stainless steel (up to 80mm), aluminum (up to 50mm), and alloy steel (e.g., quenched-tempered S690QL).
Oxygen cutting for carbon steel (kerf width: 0.3-1.2mm) and nitrogen cutting for non-ferrous metals, minimizing heat-affected zone (HAZ) ≤0.5mm.
Automation Excellence
Automatic nesting software optimizes material utilization to 92%, reducing waste compared to traditional plasma cutting (75% utilization).
Robotic loading/unloading systems handle plates up to 10 tons, enabling 24/7 unattended operation with OEE ≥85%.
Application
Wind Tower Flanges: Laser-cut bolt holes (100+ holes per flange) with H9 tolerance, meeting IEC 61400-1 flange connection standards.
Heavy Machinery: Cutting components for excavator arms (thickness: 100mm), with stress-relief notches designed via FEA to prevent crack propagation.
Energy Infrastructure: Custom shapes for nuclear reactor supports (304L stainless steel, thickness: 80mm), compliant with ASME BPVC Section III.
