Hybrid press brake WyBend H

CNC8-axishigh-speed

Overview
WEIYA WyBend H hybrid press brakes combine hydraulic force with servo-electric control to deliver energy-efficient, high-speed bending with precise angle control and repeatability. Machines are designed for industrial sheet metal production lines with automation interfaces for robotic handling and lights-out operation.

Key features

• Hybrid hydraulic‑servo drive: high-pressure hydraulic cylinders for force and servo motors for fast, energy-efficient control and adaptive compensation.
• Servo-electric angle control and closed-loop feedback for high accuracy and repeatable bends.
• Compliance: core components and assembly to ISO 9001 and CE standards.
• Low operating noise (≤65 dB(A)) and reduced energy consumption versus conventional hydraulic systems (typ. 40–48% savings).
• Preconfigured automation interfaces for sheet followers, loading/unloading systems and industrial robots.

Machine accessories (summary)
