Application:

The CNC gantry-type drilling and milling machine is specifically designed to execute drilling, chamfering, tapping, and milling processes on plate-like and structural components—such as flanges, discs, rings, and flat plates—within its valid processing scope, irrespective of the components’ thickness. It possesses the capability to drill both through-holes and blind holes in workpieces made of single materials as well as composite materials. The machining workflow is governed by digital control, which guarantees a high level of operational user-friendliness.

Specifications:

Equipment Structure:

The CNC gantry flange plate sheet drilling machine is mainly constituted by a bed worktable, a movable gantry, a movable sliding saddle, a drilling and milling power head, an automatic lubrication system, a protective mechanism, a circulating cooling device, a numerical control system, and an electrical system. With support and guidance provided by rolling guide assemblies, and driven by precision lead screw assemblies, the machine tool exhibits excellent positioning accuracy and repeat positioning accuracy.

Machine Bed and Workbench:

The CNC drill and mill machine bed is first subjected to welding, followed by annealing treatment and precision machining processes. This multi-step manufacturing approach ensures the bed exhibits superior dynamic and static rigidity, along with permanent dimensional stability. Two sets of high-precision linear guides are installed on either side of the bed base. This configuration enables even force distribution across the guide sliders, thereby significantly enhancing the machine’s overall rigidity, tensile strength, and compressive resistance.

The gantry drilling and marking machine drive system adopts AC servo motors combined with precision ball screw assemblies to implement double-sided drive, which facilitates the gantry’s smooth movement along the Y-axis. Furthermore, the workbench is integrated with a hydraulic cylinder clamping system, which delivers reliable and secure fixation of workpieces during machining operations.

Mobile Gantry

The CNC mobile gantry is fabricated from gray cast iron (HT250). Two rolling linear guides with ultra-high load-bearing capacity are mounted on the front side of the gantry. A set of precision ball screws, in conjunction with a servo motor, enables the power head slide plate to move along the X-axis; the drilling power head is installed on this power head slide plate. The movement of the gantry is realized through a servo motor, which—via a precision coupling—drives the ball screw nut to rotate on the ball screw, thereby initiating the gantry’s motion.

The CNC gantry drilling and milling machine is a high-performance industrial equipment specially engineered for the precision machining of plate-type components and structural parts. This device is tailored to process workpieces such as flanges, discs, rings, and flat plates—with the core prerequisite that the thickness of these workpieces fully complies with the machine’s specified effective machining scope.

In steel structure workshops, the equipment carries out precise drilling and milling operations on structural plates and connecting components, thereby laying a solid foundation for the stable assembly of steel frames. For the wind power sector, it performs high-precision machining on wind turbine towers and flanges—a critical process that ensures these components can withstand severe environmental conditions (e.g., strong winds, temperature variations). In bridge construction projects, the equipment processes bridge girders and brackets, which in turn guarantees stable and durable connections. These connections are designed to bear dynamic loads throughout the bridge’s extended service life.
