Equipment Structure:

This equipment is primarily composed of a cast bed workbench, a movable gantry, a mobile saddle, a drilling and milling power head, an automatic lubrication and protection system, a circulating cooling unit, a numerical control system, and an electrical system. Rolling guideways offer stable support and precise guidance, while precision ball screw drives guarantee superior positioning accuracy and excellent repeatability.

Product Features

1. Bed and Worktable:
The bed and worktable are fabricated from gray cast iron (HT250) as one-piece castings, subjected to secondary annealing and aging treatments, followed by precision machining to ensure outstanding dynamic and static rigidity with no deformation. The worktable surface is furnished with precision-machined T-slots in an optimized layout, facilitating secure workpiece clamping. The bed base is equipped with two high-precision linear guideways on each side, ensuring even force distribution across the guideway carriages and substantially enhancing the machine tool’s rigidity as well as tensile and compressive resistance. The drive system adopts AC servo motors paired with precision ball screw assemblies for bilateral drive, enabling the gantry to traverse along the Y-axis. Adjustable leveling bolts are strategically positioned on the bed base, allowing for convenient calibration of the bed and worktable’s horizontal alignment.

2. Mobile Gantry:
The mobile gantry is constructed from gray cast iron (HT250), with two ultra-high load-bearing rolling linear guideways mounted on its front side. A set of precision ball screw assemblies, paired with a servo motor, facilitates the X-axis movement of the power head slide. Drilling power heads are affixed to the power head slide for operational execution.

3. Moving Saddle:
The moving saddle is a precision-cast iron structural component, engineered for optimal rigidity and operational stability. It is outfitted with two high-load-capacity CNC linear guideways, a set of precision ball screw assemblies, and a high-precision planetary gear reducer coupled to an AC servo motor. A nitrogen gas counterbalance cylinder is integrated into the design, offsetting the weight of the power head to minimize load on the ball screw and prolong its service lifespan. The assembly drives the drilling power head to execute Z-axis movement, enabling core functions including rapid traverse, working feed, rapid retraction, and precise positioning stop. It is also equipped with automatic chip breaking, chip evacuation, and program pause capabilities to enhance machining efficiency and process control.

This high-performance CNC gantry industrial machine is dedicated to drilling and marking operations for plate and sheet metal components. It is meticulously engineered to deliver precision machining of plate-type workpieces and structural parts, with specialized adaptability to the processing of flanges, discs, rings, flat plates, and analogous components. A core requirement is that the workpiece thickness must strictly conform to the machine’s preset effective machining parameters.

In steel structure manufacturing facilities, this equipment performs precision drilling and milling on structural plates and connecting components, establishing a solid foundation for the stable assembly of steel frameworks. Within the wind energy sector, it provides high-precision machining solutions for wind turbine towers and flanges — a critical process that ensures these components can withstand extreme environmental conditions (e.g., strong winds, temperature fluctuations). For bridge construction projects, the equipment processes bridge girders and support brackets, enabling the formation of stable, durable connections engineered to endure dynamic loads throughout the bridge’s prolonged service life.
