Gantry Milling Machine Gantry Moving GMT21

(Designed and made in Qingdao Shandong, China)

1.Brief introduction :

GMT21machine is Gantry-type machining center with movable cross-rail and column. It features longitudinal movable planner, up-down movement of the cross-rail, fixed stable, large bearing capacity and well accuracy. It can mill, bore, drill various complicated workpieces in manufacturing industries such as aircraft, mould, ship, automobile, and etc.

Machine adopts fixed worktable and gantry moving structure. The gantry (X axis ) is driven by double AC servo motor and moved on the slide base. All axes movement are driven by Siemens AC servo motor. The movement of cross-rail is driven by double AC servo motor.

GMT21 ismade by the standard of ISO and can achieve various machining, milling, boring, drilling, rigid tapping and profile milling. Multiple accessory head can be equipped with the machine, in order to perform one time step up and five face machining.

Machine has good character in high rigidity, excellent accuracy and big output power. Extralong distance gantry travel can ensure best machining accuracy and highest productionefficiency when machining long guide way of heavy duty machine tool. During machiningprocess for short work-piece, the operator can load and unload another part to save auxiliary time and improve efficiency. Thereby,GMT21is the best choice for machining of base component in follow industry, heavy duty machine tool, heavy duty machinery, steel rolling mill, steam turbine and big reduction equipment.
