Vertical Bridge Gantry Mills
Product Description
Compared to traditional floor-type gantries, the vertical bridge gantry mills take an "overhead bridge" route, with all moving components above the table. Since the worktable is fixed, even if you put an 8-ton workpiece on it, it won't affect its dynamic performance during high-speed movement. It comes standard with a Siemens system, combined with a 54kW spindle motor and HSK-A100 taper. Milling high-temperature alloys is both fast and stable, making it perfect for high-intensity 5-axis simultaneous machining sessions that last over ten hours.

Product Features
Box-in-box structure resists deformation:
The crossbeam uses a symmetrical box design, with the spindle precisely at the center of the crossbeam and ram. When temperature fluctuates in the workshop, spindle center shift is minimal, preserving final machining accuracy.
Dual-gear backlash elimination + optional linear motors:
The standard X/Y axes use German Alpha racks, eliminating backlash through dual-gear pre-loading. For those needing extreme precision, THK linear motors can be installed directly, completely eliminating mechanical transmission friction.
Runs fast, stops accurately:
All three axes achieve 40 m/min rapid traverse and come standard with full closed-loop control (linear scales). Mechanical deviations are compensated in real-time by the system, ensuring no loss of steps during high-speed reciprocation.
High-rigidity spindle system:
The headstock has an independent constant-temperature oil cooling system, paired with a high-rigidity four-rail ram. Even during prolonged high-speed machining, thermal expansion won't cause spindle shift.
Product Advantages
When machining complex impellers, die-casting molds, and aerospace structural parts, the biggest advantage of this vertical bridge gantry mills lies in being "both stable and fast." Because all movement occurs above, even with an 8-ton workpiece, the machine's response remains agile. The full closed-loop system ensures smooth, refined curved surfaces, saving a lot of manual polishing labor costs. For customers looking to achieve "lights-out factories," this vertical bridge gantry mill comes standard with interfaces for robot loading/unloading, in-line inspection, and automatic workpiece calibration, making it easy to integrate into automated production lines. Moreover, among similar overhead gantry machines, its 3-meter wide table offers greater clamping space, and this vertical bridge gantry mill is the core confidence for taking on high-value-added orders.
Product Application
Vertical bridge gantry mills are widely used in aerospace (large frames, impellers, blades), automotive molds (large bumper and side panel cover dies), precision medical devices, and complex curved surface parts in high-end energy equipment. It is capable of milling, boring, drilling, rigid tapping, reaming, and counterboring, especially excelling in multi-angle, multi-face 5-axis simultaneous machining within a single setup.
Customization Options
Spindle & Milling Heads:
Standard IBAG Mepro; can be upgraded to Kessler 5-axis heads; supports optional right-angle and universal heads.
Drive Upgrades:
X/Y axes standard with Alpha racks, can be upgraded to THK linear motors (ideal for ultra-high-precision mirror mold machining).
System Expansion:
Standard Siemens; higher-end systems can be selected based on requirements; supports Renishaw probes and tool setters.
Travel Customization:
Z-axis travel can be extended to 1500mm, and spindle nose distance can be extended to 1700mm to handle taller box-type parts.
Logistics & Packaging
The heaviest lifting component of this machine is about 30 tons. It is shipped in segmented weatherproof packaging, with the bed, crossbeam, and columns fixed onto heavy-duty steel frames to prevent deformation from ocean transport. Since the overall machine dimensions can reach up to 10 meters long, we will provide a detailed packing list and foundation drawings. Upon delivery, we will send a dedicated engineer on-site to guide unloading and positioning to ensure safe placement before assembly. Please prepare the lifting wire ropes (rated for 30+ tons) in advance and confirm your workshop's ceiling height.
