Three models are available: GMC2017, GMC2517, and GMC3017.
Worktable sizes range from 1400 × 2200 mm to 1400 × 3200 mm.
Travel ranges:
X-axis up to 3200 mm
Y-axis 2000 mm
Z-axis 800 mm
This allows efficient machining of large and complex components.
The machine features a wide-span gantry structure with strong column support.
This design reduces vibration and deformation, ensuring stable performance and consistent accuracy during heavy cutting operations.
Equipped with a BT50 spindle, with speeds up to 6000 rpm.
Multiple drive options are available:
Belt drive
Gearbox drive
ZF gearbox with belt transmission
These options provide flexibility for different materials and machining requirements.
Rapid traverse: 16 m/min
Cutting feed: up to 10 m/min
High-precision ball screws and linear guides are used on X and Y axes, while the Z-axis uses a box guideway for higher rigidity.
Servo motors are directly connected to each axis, improving transmission efficiency and positioning accuracy.
Table load capacity: up to 6 tons
Machine weight: 14–17 tons
A hydraulic balancing system on the Z-axis improves stability and reduces mechanical wear during operation.
Widely used in:
 Mold manufacturing |  Aerospace components |  Heavy machinery |  Automotive tooling |  Energy equipment |
Ideal for large plates, frames, and complex structural parts.
