Equipment Structure:

This CNC gantry drilling and marking machine is primarily outfitted with a cast iron bed workbench, a movable gantry structure, a traversing saddle, a drilling-milling power head, an automatic lubrication and protection system, a circulating cooling unit, a numerical control (NC) system, and an electrical control assembly. Rolling guideways offer stable load-bearing capacity and precise motion guidance, while high-precision ball screw drive mechanisms guarantee superior positioning accuracy and excellent repeatability.

Product Features

1. Bed and Worktable:
The machine bed is constructed as a one-piece gray iron (HT250) casting, while the gantry and side beam base are fabricated from high-strength welded structures. Following secondary annealing and aging treatments, precision machining is performed to achieve exceptional dynamic and static rigidity, effectively preventing structural deformation. The worktable surface features precision-machined T-slots arranged in an optimized layout, facilitating secure workpiece clamping. Two high-precision linear guides are installed on each side of the bed base, ensuring uniform force distribution across the guide carriages and substantially enhancing the machine tool’s rigidity, tensile strength, and compressive resistance. The drive system adopts an AC servo motor paired with a precision ball screw assembly for dual-sided transmission, enabling smooth Y-axis movement of the gantry. Adjustable leveling bolts are strategically distributed on the bottom of the bed, allowing for convenient calibration of the worktable’s horizontal alignment.

2. Mobile Gantry:
The mobile gantry is constructed from gray iron (HT250) material, with two ultra-high load-bearing rolling linear guideways integrated on the front side of the gantry structure. 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 mounted on the power head slide to deliver machining functionality.

3. Moving Saddle:
The moving saddle is a precision cast iron structural assembly, outfitted with two high-load-bearing CNC linear guideways, a set of precision ball screw assemblies, and a high-precision planetary reducer coupled to a servo motor. It is further integrated with a nitrogen balance cylinder, which counterbalances the weight of the power head to minimize the load on the ball screw and prolong its operational lifespan. This component drives the drilling power head to execute Z-axis movement, enabling core functions including rapid feed, working feed, rapid retraction, and precise stopping. Additionally, it incorporates automatic chip breaking, chip evacuation, and pause capabilities to enhance machining efficiency and operational flexibility.

This high-performance CNC gantry industrial machine is specifically designed for drilling and marking applications on plate and sheet metal components. Meticulously engineered to ensure precision machining of plate-type workpieces and structural parts, it offers dedicated compatibility with the processing of flanges, discs, rings, flat plates, and analogous components. A fundamental requirement is that the workpiece thickness must strictly conform to the machine’s preset effective machining specifications.

Within steel structure manufacturing facilities, this equipment performs precision drilling and milling operations on structural plates and connecting components, establishing a solid foundation for the stable assembly of steel frameworks. In the wind energy industry, it provides high-precision machining solutions for wind turbine towers and flanges — a critical process that ensures these components can withstand severe 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.
