A heavy gantry laser cutting machine is an industrial-grade laser cutting system characterized by its robust gantry structure, designed for large format and thick plate metal cutting (e.g., carbon steel, stainless steel, aluminum).

Cutting range: Up to 3m×6m (or larger)
Material thickness: 1-50mm (with 6kW+ laser power)

• (1) High Stability & Precision
  Heavy-duty gantry: Cast iron or welded steel construction, resistant to deformation (acceleration ≥1.5G, positioning accuracy ±0.05mm/m).
  Dual-drive synchronization: Servo motors + gear racks ensure stability during high-speed cutting.
• (2) High-Efficiency Cutting
  High-power lasers: 6-30kW fiber lasers cut 30mm stainless steel (N2) or 50mm carbon steel (O2).
  Smart piercing: Burst piercing technology achieves <0.8s piercing for 20mm carbon steel.
• (3) Automation Integration
  Auto loading/unloading: Pallet changers or FMS for 24/7 operation.
  Intelligent height control: Capacitive/laser sensors adapt to uneven plates.
• (4) Advanced Software
  Nesting optimization: Professional software boosts material utilization to >90%.
  Remote monitoring: IoT platforms enable real-time diagnostics.

Heavy gantry laser cutting machines are widely used in industries requiring high-power, large-format, and high-precision metal cutting. Below are key sectors and specific use cases:

• Ship Decks & Hulls: Cutting 20-40mm carbon steel plates for ship structural components. Bevel cutting (V/K/Y grooves) for welding preparation (e.g., 30° bevels on 25mm steel).
• Offshore Platforms: Processing high-strength steel (AH36/DH36) for oil rigs and support structures.

• Wind Turbine Towers: Cutting 30-50mm thick steel rings for tower sections (precision: ±0.1mm/m).
• Nuclear/Pressure Vessels: Stainless steel (SA-240 316L) head cutting with nitrogen-assisted oxidation-free edges.
• Oil & Gas Pipelines: Flange drilling (≥2" holes on 40mm carbon steel) and pipe-end profiling.

• High-Speed Train Chassis: Aluminum alloy (6xxx series) frame cutting (8-15mm thickness, dross-free). Stainless steel (EN 1.4301) body panels with fiber laser for minimal heat distortion.
• Commercial Vehicle Frames: Cutting high-tensile steel (S700MC) for truck beams.

• Crane Booms & Excavator Arms: Hardox 450/500 wear-resistant steel cutting (up to 30mm).
• Prefab Steel Structures: Batch processing H-beams and I-beams (plasma-laser hybrid options for >50mm).

• Aircraft Components: Titanium (Ti-6Al-4V) engine parts (3-10mm, argon-assisted cutting). Aluminum honeycomb panels (low-power mode to avoid melting).
• Vehicles: Armor plate (AR500) cutting with high-pressure O2 for clean edges.

• Hydraulic Cylinders: Precision cutting DOM tubes (Ø200-500mm) for cylinder barrels.
• Gearbox Housings: Cast iron (GGG60) machining with 3D laser heads for complex contours.

• Solar Panel Mounts: Galvanized steel (2-8mm) cutting at 20m/min (high-speed mode).
• Hydroelectric Turbines: Stainless steel (CA6NM) runner blades with 5-axis laser cutting.

• Two Years Quality Guarantee: Two years quality guarantee for the main parts of the machine, excluding consuming parts, and the main parts shall be changed free of charge during the warranty time.
• Lifelong Maintenance & Support: Lifelong maintenance for the machine, and lifelong technical support from sophisticated English-speaking engineer team.
• Free Training Course: Free training course at our plant.
• Affordable Replacement Parts: We will provide the machine consuming parts with factory price when you need replacement.
• 12 Hours Online Service: 12 hours online service each day, free technical support.

• 1. Anti-collision package edge: All parts of the machine are covered with some soft materials, mainly the use of pearl wool.
• 2. Fumigation wooden box: Our wooden box is fumigated, do not need to check the wood, saving the transport time.
• 3. Whole film packaging machine: Avoid all damage that may occur during delivery. Then we will cover the plastic package tightly to ensure that the soft material is covered intact, also avoiding water and rust. The outermost is a wooden box with a fixed template.
• 4. Wooden box bottom: Features a solid iron socket for easy handling and loading.
