WJFB
Our WJFB machine redefines waterjet cutting with a dynamic fly bridge architecture—delivering exceptional reach, flexibility, and stability. Instead of a fixed gantry, the entire bridge glides smoothly across the X and Y axes, enabling expansive cuts with consistent accuracy.
Designed for large-format fabrication, its robust structure and precision motion system ensure clean, high-speed performance across metals, stone, glass, and advanced composites. The open-bed layout enhances accessibility for oversized materials—while its compact footprint makes it remarkably easy to install and prepare for containerized shipment.
Engineered for scale without compromise, the WJFB merges power, mobility, and precision in a form that adapts seamlessly to the demands of industrial-scale cutting—setting a new benchmark for flexibility and flow.
