What are the key advantages of a moving-column gantry machining center?
The moving-column design ensures a fixed quality of moving parts and requires a smaller footprint. Since the worktable remains stationary, the weight limit of the workpiece is relatively unlimited, making it ideal for heavy-duty industrial machining.
Which industries are the GMC series machining centers suitable for?
These machines are highly suitable for large-scale and high-precision fields such as automobile, shipbuilding, printing, packaging, textile, military industry, molds, construction machinery, turbines, and nuclear power.
Can the machine perform multi-surface operations in a single setup?
Yes. By equipping the machine with accessories like an automatic right-angle milling head, extension head, or universal angle head, the machining of holes and planes on multiple surfaces can be completed in a single clamping operation.
What CNC controllers are supported on the GMC series?
The standard configuration features the Fanuc 0i-MF PLUS CNC controller. Alternatively, customers can choose the Siemens 828D CNC controller as an option to suit their operational preferences.
What is the positioning accuracy of these machining centers?
The positioning accuracy (X/Y/Z) ranges from 0.055/0.032/0.022 mm for the GMC30100fm to (0.011/1000)/0.035/0.022 mm for the GMC40140fm model, ensuring high precision for large-volume parts.
