Abrasive water-jet cutting machine WJFB

for composite materialsfor aluminumfor stainless steel

Overview
The WJFB is an industrial abrasive waterjet cutting machine featuring a dynamic fly-bridge architecture. The moving bridge traverses the X and Y axes while the table remains open, enabling large-format cuts with consistent precision. Engineered for fabrication environments, the WJFB supports metals, stone, glass and advanced composites without thermal distortion. Compact packing and container-ready dimensions simplify transport and site deployment.

Key features

• Moving fly-bridge design for improved accessibility to oversized and irregular parts.
• Open-bed layout for loading large sheets and plates from overhead or sides.
• High-precision linear motion delivering ±0.03 mm linear accuracy and ±0.02 mm repeatability.
• Max traverse speed 12 m/min for efficient large-format processing.
• Compatible with Jekran direct-drive pumps (22 kW / 30 kW) up to ~4,000 bar.
• Suits metals, stone, glass, composites — no heat-affected zone from cutting.

Design / Use Cases
Designed for industrial-scale fabrication and custom workshops: the WJFB handles thick plate cutting, nested parts from large sheets, architectural stone panels and delicate composite or glass components where thermal-free cutting is required.
