Equipment Structure:

The machine base is constructed from cast material and primarily comprises the worktable, movable gantry, sliding saddle, drilling and milling spindle head, automatic lubrication system, protective enclosure, circulating cooling system, digital control unit, electrical system, and additional components. It features hardened rolling rail pairs for support and guidance, as well as precision lead screw pairs for motion transmission. The machine is distinguished by high positioning accuracy and excellent repeatability.

Product Features

1. Machine Bed and Workbench:

The machine bed is constructed from cast material and comprises two main components. It undergoes high-temperature annealing before machining, followed by secondary stress-relief annealing after semi-finishing, and is then subjected to final machining. This multi-stage process ensures long-term stability and precision of the machine. The workbench is a single-piece casting made of gray iron (HT250), which is subsequently treated with secondary annealing and aging. This treatment provides outstanding dynamic and static rigidity, effectively preventing deformation. The work surface is equipped with a series of T-slots arranged in an optimized layout for secure clamping of workpieces.

Two high-precision linear guides are mounted on either side of the bed base to ensure uniform load distribution along the guide rails. This arrangement significantly enhances the machine’s rigidity, as well as its tensile and compressive strength. The drive system is powered by an AC servo motor paired with a precision ball screw, enabling accurate Y-axis movement of the gantry. Adjustable bolts are positioned beneath the bed to allow convenient leveling of the workbench.

2. Movable Gantry:

The movable gantry is fabricated from gray iron (HT250) and is fitted with two high-capacity linear guide rails on its front face. Movement of the power head slide along the X-axis is facilitated by a precision ball screw pair driven by a servo motor. The drilling power heads are mounted directly on this slide plate. Gantry motion is achieved through the rotation of the ball nut on the ball screw, which is actuated by the servo motor via a precision coupling.

3. Moving Saddle:

The movable sliding saddle is a precision-cast iron component. It is equipped with two high-capacity CNC linear slide tables, a precision ball screw pair, and a high-accuracy planetary reducer connected to the servo motor. Additionally, the saddle incorporates a nitrogen gas balance cylinder, which compensates for the weight of the power head, reducing the load on the screw and extending its service life. This system facilitates Z-axis movement of the drilling power head, enabling operations such as rapid approach, work feed, quick retraction, and precise stopping. It also features automatic chip removal, chip ejection, and pause functions to enhance operational efficiency.

This advanced CNC gantry system is purpose-built for high-efficiency drilling and marking of plate and sheet metal components. It has been precisely engineered to ensure accurate machining of plate-like workpieces and structural assemblies, making it well-suited for processing flanges, discs, ring-shaped components, flat plates, and similar items. A fundamental operational requirement is that the workpiece thickness must fall within the machine’s specified effective machining range.

In steel structure fabrication facilities, this equipment performs high-precision drilling and milling on structural plates and connection components, providing a solid foundation for the reliable assembly of steel frameworks. In the wind energy sector, it offers advanced, high-accuracy machining for wind turbine towers and flanges, ensuring these components are engineered to withstand severe environmental conditions, including extreme wind and temperature fluctuations. In bridge construction, the equipment machines bridge girders and support brackets, enabling the formation of durable, stable connections capable of withstanding dynamic loads throughout the structure’s extended service life.
