GMC2516 has a large-sized work table of 1400x2600mm and can hold up to 5 tonnes, much more so than other medium-sized gantry machines. The X/Y/Z-axis travel is up to 2500mm x 1700mm x 800mm; The gantry width is set at 1700mm and the passage height is fixed at 1080mm, providing stable processing conditions for large-mould-base work-pieces, heavy-structure-beam work-pieces, wind-power equipment bracket work-pieces, and marine-engine component work-pieces. A fixed-column-fixed-beam Design and reinforced-frame Structure to distribute forces evenly, reduce Deformation due to heavy load or long-term Continuous work.

The main components, including the gantry beam, columns and beds, of all parts have been produced in good quality Grade HT300 grey cast iron using the moulding technology after artificial aging combined with natural-ageing stress-relief treatment to ensure long-lasting accuracy. Based on the optimization of a closed box-beam that contains triangular-reinforcing-rib structures using finite element methods, it improves stiffness and damping performance to reduce vibrations during materials processing . A BT50 high-precision spindle is equipped; the precision ball screw is grade C3; Optional A total closure-of-grinding sensor scale control system has been selected to continuously correct for processing errors, resulting in an absolute positional error within 0.008mm/m and a repeatability of ±0.006mm..

A high-power, stable-spindle motor is used to provide sufficient power for heavy-duty work; the speed range covers three segments: low-speed 30-875RPM and medium-speed 40-6000 RPM within one range of operation including drill-milling-turning etc. Standard equips a 24-station disc-type tool magazine (optionally, 32/40 stations), with a tool-change time of less than three seconds; Multi-process continuous operation can be achieved to reduce non-processing time . The spindle has milling, boring, drilling, Tapping and Counter-boring function; optionally installed a right angle mill head or a four-axis CNC indexing table which can achieve multi-angle, five-sided processing during one clamp for complex parts' processing.

Compared with previous ones, this one uses a closed electrical cabinet and titanium-alloy-coated guiding parts to improve corrosion-resistant performance under humid and saline-saturated work environment; Under harsh workshop environmental conditions or tropical high-temperature-high-humidity circumstances. Having a convenient to operate CNC system (Fanuc OI-MF Plus, Siemens 828D or Mitsubishi M80A type) that supports three axis positioning; It is also able to perform program relocation at distance remotely and diagnose faults automatically . Also equipped with an automatic Centralized lubrication system for spindles, a water-jacketed spindle and a double spiral chip conveying device that can extend component lifespans; operates continuously during the entire day uninterrupted.
