GMC-4025 Generous Working Stroke Gantry Machining Center

Specific Applications

This Generous Working Stroke Gantry Machining Center is specially designed for mass milling, drilling, and tapping of ultra-long, extra-wide oversized plates, cast aluminum components, and widened extended cast iron racks, suitable for mass production of various wide ultra-long heavy structural parts. Core applicable industries are listed as follows:

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
Steel Structures: Thick steel racks and large welded frames
Heavy Hardware: Large valve bases, protection frames and metal fixture pedestals

Core Functions

•  High-Rigidity Gantry Structure: The GMC-4025 Generous Working Stroke Gantry Machining Center uses an integral high-strength resin sand cast structure with multiple aging and stress-relief treatments. The extra-wide enclosed gantry helps resist deformation and vibration during long-travel heavy cutting. 
• BT50 High-Torque Spindle: The BT50 heavy-duty spindle uses an independent constant-temperature oil-air lubrication and cooling system to control temperature during continuous drilling, milling, and tapping, supporting heavy stock removal. 
•  Extra-Long Travel Transmission: Extra-wide heavy-duty roller linear guides and double-nut preloaded ball screws provide high load capacity and stable axis movement, helping reduce thermal deformation during ultra-long travel machining. 
•  Multi-Option CNC Platform: FANUC, Mitsubishi, Siemens, and Syntec CNC systems are available, with dedicated heavy-cutting process functions, ultra-long travel program processing, 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.
