CNC Plate and H-Beam Cutting Machine | Structural Steel Profile Processing System
This CNC Plate and H-Beam Cutting Machine integrates flat sheet nesting and structural profile coping into a single workstation. Engineered for heavy fabrication yards, structural steel plants, and shipyards, it eliminates the need for separate cutting lines.
Dual-Function Architecture: Combines a heavy-duty rail-type plate cutting gantry with a dedicated rotary axis for H-beam, channel, and angle steel processing.
Rigid Structural Foundation: Stress-relieved steel gantry and heavy-wall box-type beam construction minimize vibration during high-speed plasma or oxy-fuel cutting.
Drive System: Dual-side AC servo motors paired with planetary gearboxes deliver smooth acceleration and deceleration under heavy load.

Application & Material Compatibility
Structural Steel Construction: Coping, slotting, and bolt-hole cutting on H-beams, I-beams, and channels for high-rise buildings and industrial plants.
Shipbuilding & Offshore: Processing web plates, stiffeners, and deck panels simultaneously to reduce material handling time.
Material Range: Carbon steel (Q235, Q345, ASTM A36), stainless steel (304/316L), and structural alloy steels up to 100 mm thickness (oxy-fuel) or 50 mm (HD plasma).
Manufacturing Process & Quality Control
Thermal Stress Relieving: All welded mainframes undergo vibration stress relief (VSR) and annealing furnaces at 650°C to eliminate residual welding stress before precision CNC machining.
Gantry Machining: Guide rail mounting surfaces are milled on a 12-meter floor boring machine in a constant-temperature workshop to ensure parallel alignment within 0.05 mm.
Factory Inspection: Every machine undergoes a 72-hour continuous dry-run test, laser interferometer calibration for positioning accuracy, and a strict gas/fluid leakage test before crating.
Supplier Evaluation & Commercial Terms
Standard Lead Time: 45 to 60 days from drawing approval.
Documentation Package: English operation manuals, electrical schematics (EPLAN format), foundation layout drawings, and CE compliance certificates.
Warranty & Support: 12-month warranty on core mechanical and electrical components (CNC controller, servo drives, gearboxes). Remote diagnostics via secure VPN module integrated into the control cabinet.
Frequently Asked Questions
Q: Can the machine switch between plate cutting and H-beam processing without manual reconfiguration?
A: Yes. The CNC controller utilizes multi-axis linkage (typically 4 to 6 axes). Operators select the cutting program via the HMI interface, and the system automatically engages the rotary chuck for beam indexing or switches to the flat table gantry without mechanical repositioning of the tracks.
Q: What CAD/CAM nesting software is compatible with the control system?
A: The system runs on industrial CNC units (such as Hypertherm Edge Connect or Burny 10LCD) that accept standard G-code and ESSI files. It is fully compatible with mainstream fabrication software including FastCAM, SigmaNEST, and ProNest for automated plate nesting and structural profile intersection programming.
Q: How is thermal deformation managed during thick plate oxy-fuel cutting?
A: The cutting table features a sectional down-draft fume extraction design with pneumatic zone valves that open only beneath the active cutting torch. For heavy plates exceeding 50 mm, the system applies programmable lead-ins, corner slowdown routines, and multi-torch spacing to dissipate localized heat concentration.
Q: What utilities and site preparations are required prior to installation?
A: Site requirements include a reinforced concrete foundation (minimum 250 mm thickness), 3-phase 380V/480V power supply (customizable), dry compressed air (0.7 MPa, oil/water filtered), and bulk gas supplies (Oxygen, Propane, or Nitrogen/Air for plasma depending on source specifications). Detailed civil engineering drawings are provided upon contract signing.
Q: How are replacement parts and consumables supplied internationally?
A: Standard wear parts (plasma nozzles, electrodes, shield caps, ceramic rings) are kept in stock for immediate dispatch via DHL/FedEx. Major electrical components (Siemens/Schneider contactors, Panasonic/Yaskawa servo drivers) are globally sourced standard industrial parts, allowing local sourcing to minimize equipment downtime.
