Hydraulic press brake WyBend G

CNC8-axislarge

Overview
The WyBend G series is engineered for ultra-heavy metal fabrication, delivering 8000–20000 kN bending force with 6000–12000 mm bending length. Built for shipbuilding, bridge components, construction machinery and large structural steel, the series features a reinforced gantry frame, high-pressure hydraulic drive and multi-axis CNC control to ensure accurate bending of thick plates (up to 50 mm) and high-strength steels with minimal deflection.

Key features

• Heavy-duty gantry frame with FEA-optimized reinforcement to reduce deflection and torsion across ultra-long tables.
• High-pressure hydraulic drive providing uniform bending force along long rams; system pressure up to 35–40 MPa.
• Multi-axis CNC control (supports up to 8+1 axes) for precise multi-step bends and automatic angle calculation.
• Capable of bending very thick plates: carbon steel up to 50 mm; high-strength steels up to ~40 mm depending on model and tooling.
• Designed for large-scale applications: shipbuilding, bridges, wind towers, and heavy construction machinery.
