CNC Electro Hydraulic Servo Press Brake Machine

CNC Electro Hydraulic Servo Press Brake Machine：

Advanced Electro-Hydraulic Proportional Servo Synchronization (Y1/Y2 Dual Axis)

The XINNUO CNC Electro-Hydraulic Servo Press Brake Machine represents the pinnacle of modern sheet metal fabrication technology, delivering uncompromising bending accuracy, high dynamic response, and energy-efficient operation for industrial sheet metal workshops. Utilizing advanced dual-cylinder electro-hydraulic proportional servo control (Y1/Y2 axes), the system continuously monitors the ram position on both sides in real time using high-precision optical linear encoders with 0.005 mm resolution. The independent closed-loop feedback system dynamically modulates the flow through German high-response proportional servo valves, guaranteeing absolute synchronization and parallel leveling between the upper ram and lower worktable even under eccentric or off-center bending loads.

Robust Stress-Relieved Monoblock Frame & Precision Mechanical Crowning

Structural rigidity is the foundation of flawless sheet metal bending. The main frame of the press brake is constructed from high-tensile solid steel plates, welded as an integrated monoblock structure and processed through comprehensive thermal tempering and vibration stress-relief treatments. This eliminates internal welding stresses and prevents mechanical frame distortion under maximum operating tonnage. To ensure uniform angular consistency across full bending lengths without deflection, the machine is equipped with an automated CNC-controlled mechanical dynamic deflection compensation (crowning) system on the lower worktable. The CNC system automatically calculates the required compensation curve based on material thickness, tensile strength, tool parameters, and bending length, completely eliminating the center-angle deviation common in traditional bending machines.

Multi-Axis High-Speed Backgauge & Fast Tool Clamping System

To accommodate complex multi-step bending sequences with minimal cycle times, the press brake incorporates a heavy-duty CNC multi-axis backgauge system (standard X + R axes, expandable to Z1, Z2, X1, X2, R1, R2). Driven by high-dynamic AC servo motors through precision ground ball screws and dual linear guideways, the backgauge fingers achieve swift positioning speeds with positional repeatability within ±0.02 mm. The upper ram is equipped with a European standard quick-clamp mechanism, enabling rapid, tool-less punch replacement from the front side, dramatically reducing tooling setup and changeover times. Segmented precision-ground punches and multi-V lower dies made from 42CrMo high-alloy tool steel provide versatile processing flexibility for small intricate components as well as wide sheet enclosures.

Intelligent CNC Controller, Ergonomic Operation & International Safety Compliance

The machine is equipped with an intuitive color touchscreen CNC controller (such as Delem, Cybelec, or ESA) mounted on a 360-degree swiveling pendant arm, offering graphical 2D/3D programming, automatic bend sequence optimization, collision detection, and extensive material libraries. Operating ergonomics are enhanced by a mobile foot pedal console fitted with safety interlocks and an integrated emergency stop. For operator safety and CE compliance, the press brake incorporates dual optical safety light curtains, interlocking rear and side protective doors, and an intelligent overload hydraulic safety circuit. Manufactured in accordance with strict ISO9001 quality protocols, every XINNUO press brake undergoes comprehensive 72-hour full-load testing and laser angle verification before shipment, backed by lifetime engineering support, remote diagnostics, and prompt global spare parts delivery.
