250mm Thickness CNC Gantry Metal Plate Steel Drilling Machine 22/30KW Servo Spindle Motor Power

250mm Thickness CNC Gantry Metal Plate Steel Drilling Machine 22/30KW Servo Spindle Motor Power

Product Introduction:

The CNC gantry-type drilling and milling machine is primarily designed for the machining of tube sheets, flanges, bearings, heat exchangers, and other components in sectors such as petrochemicals, nuclear power, wind energy, boilers, and steel structures. It supports high-speed drilling operations using carbide drill bits with internal cooling or high-speed twist drills with external cooling. This versatile machine performs a variety of tasks, including drilling, chamfering, tapping, milling, and boring. Additionally, it can be fitted with an optional automatic right-angle head to enable side drilling, tapping, and milling functions.

Product features

1. The plate sheet and flange drilling, milling, and marking machine consists of several essential components, including the bed, 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 critical elements.

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 high-precision Taiwan-made spindle (featuring internal cooling) with a BT50 taper hole, and incorporates a butterfly spring automatic broaching mechanism. This configuration facilitates convenient tool changes through the use of a connecting rod and a hydraulic cylinder tool loosening system, allowing for quick interchangeability between drill bits and milling cutters.

3. The structure of the drilling and marking machine is equipped with high-precision linear guides, ensuring smooth and stable motion. 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 made from castings or welded high-quality steel plates. These components undergo a high-temperature annealing process prior to machining, followed by a second annealing after semi-finishing to alleviate internal stresses. Subsequently, they are precision-machined to guarantee consistent accuracy and stability.

The CNC gantry plate cutting machine is a high-performance industrial solution, expertly designed for the accurate machining of plate-like components and structural elements. This equipment is specifically intended to process workpieces such as flanges, discs, rings, and flat plates, with the critical condition that the thickness of these workpieces falls within the machine's designated effective machining range.

In steel structure manufacturing facilities, this plate drilling machine performs precise drilling and milling operations on structural plates and connecting components, providing a robust foundation for the stable assembly of steel frameworks. In the wind power sector, it offers high-precision machining for wind turbine towers and flanges—critical processes that ensure these components can endure demanding environmental conditions (e.g., strong winds, temperature variations). For bridge construction projects, the equipment processes bridge girders and supports, guaranteeing the creation of stable and resilient connections capable of withstanding dynamic loads throughout the bridge's extended service life.
