GMC-2018 High Rigidity Gantry Machining Center

GMC-2018 High Rigidity Gantry Machining Center is a large CNC machining center designed for heavy cutting and precision machining of large workpieces. It uses a fixed gantry structure with a moving table, a high-power BT50 spindle, and heavy-duty guide systems for stable machining. With 2000 mm X-axis travel, 1800 mm Y-axis travel, and 800 mm Z-axis travel, it is suitable for large molds, metal plates, and structural components requiring milling, boring, drilling, and tapping.

Specific Applications

GMC-2018 High Rigidity Gantry Machining Center is suitable for:

Construction Machinery: Equipment racks, load-bearing frames, and mounting base plates
New Energy: Energy storage frames, battery bases, and aluminum box plates
Automation Equipment: Equipment bases, support girders, and assembly frames
Sheet Metal & Steel Structures: Thick steel racks and welded frames
Heavy Hardware: Valve bases, protection frames and fixture pedestals

The GMC-2018 High Rigidity Gantry Machining Center is designed for production environments requiring high load capacity, rigid cutting support, and large machining space.

Core Functions

•  High-Rigidity Gantry Frame: The GMC-2018 High-Rigidity Gantry Machining Center features an integral high-strength gray cast iron gantry frame with multiple stress-relief treatments. The rigid structure and box ways help reduce vibration and deformation during continuous heavy cutting. 
•  ISO50 Belt-Driven Spindle: The ISO 7:24 No. 50 belt-driven spindle delivers up to 6,000 rpm and 140/165 N•m torque, supporting milling, drilling, and tapping of steel and cast iron with BT50 tooling. 
•  Heavy-Duty 3-Axis Transmission: Size 45 roller linear guides and large ball screws (X: 6310, Y: 5512, Z: 5010) provide high load capacity and stable axis movement for long-duration machining. 
 Multi-Brand CNC Platform: FANUC, Mitsubishi, Siemens, and Syntec CNC systems are available, supporting machining cycles, complex contour programs, and self-diagnosis functions. Schneider electrical components are included as standard. 
•  Complete Protection & ATC: Fully enclosed guards, automatic central lubrication, and a spindle cooling device support reliable operation. The 24-station arm-type ATC accommodates BT50 tools with different sizes and weights.
