Bridge Type CNC Gantry Machining Center for Large Workpieces, High-Speed Milling and Precision Five-Axis Optional Processing
The Bridge Type CNC Gantry Machining Center is a high-rigidity CNC machine designed for large workpieces, precision milling, drilling, tapping, boring, contour machining, and complex surface processing. The equipment adopts a bridge-type gantry structure with a fixed bed and fixed worktable, making it especially suitable for large parts that require stable support during high-speed and high-precision machining.
During machining, the gantry crossbeam moves along the left and right guide rails in the X-axis direction, the slide seat moves along the crossbeam in the Y-axis direction, and the spindle box moves vertically in the Z-axis direction. This structure allows the worktable to remain fixed while the bridge gantry system performs coordinated movement, helping improve machining stability for heavy and large-size workpieces.
The equipment adopts a bridge type gantry structure. During processing, the overhead crane frame (crossbeam) moves along the left and right guide rails in the X-axis direction, the slide seat moves on the crossbeam in the Y-axis direction, and the spindle box moves up and down in the Z-axis direction on the slide seat. The bed and worktable are fixed.
The overall bed and foundation components are made of oil resin sand molding and high-strength cast iron material cast in one piece. The bed and worktable adopt a compact integrated U-shaped structure, providing a stable base for all axial movements. X, Y and Z axes adopt high-precision ball screw transmission, which combines machining accuracy and rigidity.

The Bridge Type CNC Gantry Machining Center is mainly used for milling, drilling, tapping, boring, contour machining, and precision processing of large workpieces. It is suitable for molds, aerospace components, automotive parts, rail transit parts, large aluminum alloy parts, and structural metal components.
The bridge-type gantry structure keeps the bed and worktable fixed while the gantry crossbeam, slide seat, and spindle box move along the X, Y, and Z axes. This design provides better support for large workpieces, improves machining stability, and helps maintain high precision during heavy or high-speed machining.
The integrated U-shaped structure provides a more stable foundation for all axial movements. It improves overall machine rigidity, reduces vibration, and helps ensure accurate machining performance for large and complex workpieces.
