GMC-3018 Heavy Load Capacity Gantry Machining Center

Specific Applications

This heavy-load-capacity gantry machining center is specially designed for mass milling, drilling, and tapping of ultra-long, extra-heavy plates, cast aluminum components, and cast iron racks, suitable for large-scale volume production of oversized heavy structural parts, widely used in component manufacturing of various industries:

Construction Machinery: Equipment racks, load-bearing frames and mounting base plates
Energy Storage: Energy storage frames, battery bases and aluminum box plates
Automation Equipment: Heavy equipment bases, support girders and assembly frames
Heavy Hardware: Large valve bases, protection frames and metal fixture pedestals

Core Functions

High-Rigidity Gantry Structure: The GMC-3018 Heavy Load Capacity Gantry Machining Center uses an integral high-strength resin sand casting with complete stress relief. The wide-span stepped crossbeam provides strong bending resistance for stable heavy-duty cutting with a maximum table load of 6,000 kg. 
BT50 High-Torque Spindle: The BT50 heavy-duty spindle uses an independent constant-temperature oil-air lubrication and cooling system to help control temperature during continuous drilling, milling, and tapping, supporting heavy stock removal. 
Heavy-Duty Large-Travel Transmission: Widened heavy-duty roller linear guides and double-nut preloaded ball screws provide high load capacity and stable movement across the 3,000 mm X-axis travel, helping maintain dimensional consistency during long-travel machining. 
Multi-Option CNC Platform: FANUC, Mitsubishi, Siemens, and Syntec CNC systems are available, supporting heavy-cutting process functions, long-travel machining programs, and self-diagnosis. 
Complete Protection & Chip Management: Fully enclosed guards, double-sided high-flow spiral chip conveyors, automatic lubrication, and spindle cooling support continuous machining. Optional 4th-axis and through-spindle coolant configurations are available.
