The Heavy-Duty Gantry Center for Large Parts represents the pinnacle of large-scale machining technology, engineered to handle oversized workpieces with uncompromising precision and stability.
| Quantity: | |
|---|---|
Its robust gantry structure, combined with high dynamic performance, makes it an indispensable solution for industries requiring machining of components exceeding standard size limitations. Unlike conventional machining centers, this gantry system offers exceptional rigidity across extended travel ranges, ensuring consistent accuracy even when processing workpieces weighing up to 150,000 kg — a capability that redefines productivity in heavy manufacturing sectors .
The machine features a double-column gantry design with a one-piece cast iron base, eliminating structural deformation during high-load operations. This architecture provides superior vibration damping, critical for maintaining precision in long-duration machining cycles.
Equipped with a 50 kW high-torque spindle, the gantry center delivers consistent power across its speed range (50-3,000 RPM), enabling efficient roughing and finishing of tough materials like alloy steel and cast iron . Optional 30,000 RPM high-speed spindles cater to applications demanding fine surface finishes.
Driven by precision servo motors, the X/Y/Z axes achieve rapid traverse rates of 7,500 mm/min on X-axis, ensuring minimal non-cutting time during large part positioning. The thermosymmetric design with active cooling systems minimizes thermal expansion effects on accuracy .
Parameter | Specification |
X/Y/Z Axis Travel | 18,000 mm / 4,500 mm / 2,000 mm |
Maximum Workpiece Weight | 150,000 kg |
Spindle Power | 50 kW (standard) |
Spindle Speed Range | 50-3,000 RPM |
Positioning Accuracy | ±0.005 mm/m |

Processing large structural components such as aircraft wing spars and rocket fuel tank assemblies, where the machine’s 15-meter X-axis travel enables one-piece machining of previously segmented parts .
Manufacturing critical components for wind turbines (main shafts, nacelle housings) and nuclear power equipment, where the gantry’s load capacity handles heavy forgings with diameters up to 4.5 meters.
Producing locomotive bogie frames and construction equipment bases, with customers reporting 2x efficiency gains compared to traditional multi-setup machining .
It efficiently machines carbon steel, alloy steel, cast iron, and non-ferrous metals like aluminum. Specialized tooling options extend capabilities to composite materials used in aerospace.
Integrated core cooling systems for spindle and guideways, combined with temperature-compensating software, maintain accuracy even in fluctuating shop environments.
Robotic workpiece loaders, automatic tool changers (up to 60 tools), and pallet systems can be integrated for lights-out production of large components.
