Automatic Tool Changer CNC Flange Metal Plate Sheet Drilling Machine 80mm Drilling Diameter
Application:
The CNC gantry-type drilling and milling machine for steel plates is primarily employed in the processing of tube sheets, flanges, bearings, heat exchangers, and other components across industries such as petrochemical, nuclear power, wind energy, boilers, and steel structures. It is capable of high-speed drilling using carbide drill bits with internal cooling or high-speed twist drill bits with external cooling. The machine supports a variety of functions, including drilling, chamfering, tapping, milling, and boring. Furthermore, it can be equipped with an optional automatic right-angle head for performing side drilling, tapping, and milling operations.

Product features
1.The plate sheet and flange drilling, milling, and marking machine consists of several key components, including a base, longitudinal slide, gantry, transverse slide, vertical feed unit, drilling and milling spindle, worktable, cooling system, automatic chip removal system, automatic lubrication system, pneumatic system, electrical system, and other essential parts.
2. The servo-driven sliding drilling power head of the CNC steel plate cutting machine is capable of performing drilling, reaming, tapping, chamfering, and groove milling operations. It can function either in conjunction with other units or independently. The drilling spindle is equipped with a precision Taiwan-made spindle (internal cooling) featuring a BT50 taper hole, and is integrated with a butterfly spring automatic broaching mechanism. This configuration facilitates easy tool replacement via a connecting rod and hydraulic cylinder tool loosening system, allowing for rapid changes between drill bits or milling cutters.
3. The structure of the drilling and marking machine is equipped with high-precision linear guides, ensuring seamless movement. An AC servo motor drives a synchronous belt and precision ball screw assemblies, ensuring exceptional accuracy.
4. The frame and gantry of the metal plate gantry machine are fabricated from castings or welded high-quality steel plates. These components undergo high-temperature annealing prior to machining, followed by a second annealing process after semi-finishing to alleviate internal stresses. They are then precision-machined to ensure consistent accuracy and stability.
The CNC gantry plate cutting machine is a high-performance industrial solution, carefully designed for the precise processing of plate-shaped components and structural elements. This equipment is specifically configured to handle workpieces such as flanges, discs, rings, and flat plates, with the key stipulation that the thickness of these workpieces remains within the machine's designated effective machining capacity.
In steel structure fabrication workshops, this plate drilling machine performs precise drilling and milling operations on structural plates and connecting components, providing a reliable foundation for the stable assembly of steel frameworks. In the wind energy sector, it offers high-precision machining for wind turbine towers and flanges—an essential process that ensures these components can endure challenging environmental conditions (e.g., high winds, temperature fluctuations). For bridge construction projects, the equipment processes bridge girders and supports, ensuring the creation of stable and durable connections capable of withstanding dynamic loads throughout the bridge's extended service life.
