Introduction
As heavy industries—steel structures, shipbuilding, construction machinery, and pressure vessels—shift toward automated, high-precision, long-part integrated processing, traditional gantry flame cutters face dimensional limitations, standard robot arms lack reach, and manual beveling suffers from poor consistency. Wuxi LEYOUNG Laser Technology, with over a decade of R&D in intelligent thermal cutting equipment, announces the launch of its 7‑axis floor‑track collaborative robotic oxy‑fuel cutting workstation. Featuring a fully linked 7‑axis kinematic architecture, a new BOCHU intelligent control system, AI vision perception, and code‑free programming, combined with reliable flame cutting technology and full‑process digital control, it addresses automation gaps in large carbon‑steel component blanking, delivering an efficient, cost‑effective, and highly consistent intelligent cutting solution for heavy plate fabrication.
Background: Addressing Core Pain Points in Heavy Plate Processing
Current domestic heavy component blanking faces multiple bottlenecks:
- – Traditional gantry cutters support only 2D planar cutting, unable to handle spatial profiles or multi‑angle continuous bevels, requiring secondary milling/grinding.
- – Fixed 6‑axis robots have limited reach; plates over 6m must be cut in segments, introducing step marks and cumulative dimensional errors.
- – Conventional equipment relies on manual teach‑programming and fixture positioning—high skill requirements, poor adaptability, and inflexible workpiece placement.
- – Bevel types are limited, failing to meet diverse fabrication needs.
- – Manual flame cutting depends heavily on operator experience, resulting in angle fluctuations, heavy dross, and extensive pre‑weld grinding.
- – For ultra‑thick plates (30mm+), plasma/laser consumables are costly; ordinary equipment cannot balance cost and quality for thick materials.
Our R&D team integrated multi‑axis motion algorithms, heavy‑duty floor transmission, precision flame gas control, and intelligent vision to develop this workstation, overcoming programming complexity, positioning constraints, and limited bevel variety while delivering long stroke, 3D flexible cutting, full automation, and economical thick‑plate processing.
Machine Architecture & Core Technical Advantages
The system uses a 6‑axis industrial arm plus a heavy‑duty ground seventh axis—fully synchronized for interpolation motion. It incorporates the BOCHU intelligent control system, laser stereo vision, AI trajectory optimization, servo torch height control, CNC proportional gas regulation, and multi‑layer safety protection. Modular hardware allows customization. Key advantages:
1 Full 7‑Axis Synchronization, Seamless Cutting of Extra‑Long Workpieces
The heavy‑duty pre‑embedded hardened floor track offers modular lengths from 3 to 20m. Dual servo rack‑and‑pinion drives with electronic correction ensure full interpolation between track and arm. Long steel plates, box girders, and tower sections are cut in one pass—no step marks. Dimensional tolerance ≤0.1mm/10m, bevel angle tolerance ±1°. The wrist supports J6 infinite rotation and bevel angles from –20° to +65°, enabling I, V, Y, K, and variable‑angle bevels in a single setup.
2 Rigid, Heavy‑Duty Construction for Long‑Term Precision
The base and moving carriage use thickened box‑welded structures with vibration + natural aging stress relief. Hardened guide rails and anti‑backlash helical gearing deliver repeatability ±0.02mm/m. The machine resists thermal vibration and deformation, supporting 24/7 continuous production with minimal accuracy degradation over years.
3 Superior Flame Cutting Quality
Processes 5–100mm carbon steel and low‑alloy manganese steel. Dual‑channel split CNC torches with THC servo height control produce uniform, straight cut faces with clean upper edges, minimal dross (easily removed), narrow HAZ, and smooth bevel surfaces (angle tolerance ±1°). Batch parts exhibit consistent quality, reducing grinding labor by over 60%. Supports propane, acetylene, or natural gas with four‑stage proportional valves for automatic gas adjustment during preheat, piercing, cutting, and arc‑closing—eliminating burn‑through or incomplete cuts.
4 BOCHU Smart System + Stereo Vision: Fully Automatic, Code‑Free, Teach‑Free
The BOCHU high‑end control system, paired with a high‑precision laser stereo camera, scans the entire worktable to precisely identify workpiece position, dimensions, and contours. The laser sensor auto‑locates the edges to be cut, plans optimal trajectories, and avoids idle passes—significantly boosting overall efficiency. This eliminates manual programming and teach‑point entry, lowering operator skill requirements and enabling rapid production ramp‑up.
5 Full Bevel Variety for Complex Geometries
Leveraging the BOCHU system’s powerful process algorithms, the workstation handles straight, circular, internal circular, continuously variable‑angle, and segmented bevels—perfect for diverse structural and welded assemblies, replacing multiple manual finishing steps and improving part integrity.
6 Free Workpiece Placement—No Fixturing Required
With laser vision and intelligent compensation, multiple workpieces can be placed at arbitrary positions and orientations on the same table without dedicated fixtures or manual alignment. The system automatically recognizes each part, matches the optimal cutting path, and compensates for positional deviations—greatly enhancing flexibility for multi‑variety, small‑batch, mixed‑line production.
7 Cost‑Effective Thick‑Plate Processing with Low Consumable/Maintenance Costs
For carbon steel over 30mm, flame cutting offers significant consumable savings versus plasma/laser—no electrodes or ceramic nozzles. The gas train includes multi‑stage pressure regulators, dry flashback arrestors, and gas shut‑off valves, ensuring controllable consumption. Enclosed steel drag chains protect hoses and cables, reducing failure rates and simplifying routine maintenance.
8 Modular Customization for Flexible Production Layouts
Track length, robot payload, reach, and bevel stroke are customizable. The system can operate as a standalone cell or integrate with material handling lines and smart racks for automated workflow. Ethernet and RS485 ports enable connection to MES and digital twin dashboards, with full traceability of cutting time, gas usage, and program parameters—supporting factory digitalization.
Key Application Industries
Designed for high‑volume blanking and automated beveling of heavy, long carbon‑steel components:
- Shipbuilding & offshore: deck sections, bulkhead plates, thick marine profiles.
- Bridge steel structures: box girders, H‑beams, load‑bearing plates with long bevels.
- Wind power: tower flanges, base frames with heavy profiles and bevels.
- Pressure vessels: head and shell plates, meeting various weld bevel standards.
- Construction & mining machinery: frames, counterweights, wear‑resistant heavy plates.
- Lifting equipment & heavy infrastructure: large frames, bases, structural blanks.
Value Summary
This new 7‑axis floor‑track robot workstation, powered by BOCHU control and laser‑vision AI, resolves the five major limitations of traditional thermal cutting—limited stroke, 2D‑only processing, complex programming, single bevel type, and fixture‑dependent positioning. It integrates five core benefits: ultra‑long reach, 3D flexible beveling, fully automatic code‑free operation, free workpiece placement, and economical high‑precision thick‑plate cutting.
Intelligent trajectory optimization reduces idle motion and boosts throughput; automation lowers labor costs; multi‑bevel capability reduces downstream processes; and free placement adapts to diverse production demands. Internally, it minimizes process steps, grinding labor, and defect rates while improving efficiency. Externally, it meets the trend toward larger, more precise, and smarter components in infrastructure, marine, and heavy engineering—balancing quality, productivity, and total cost.
