CNC Electro-Hydraulic Servo Press Brake for Sheet Metal Bending
High-Precision Dual Cylinder Synchronization: Fully closed-loop electro-hydraulic servo control system (Y1/Y2) driven by international brand servo valves and high-resolution optical linear scales for extreme repetitive positioning accuracy (±0.01 mm).
CNC Mechanical Crowning & 4+1 / 6+1 Axis Backgauge: Equipped with CNC-controlled dynamic wedge crowning on the lower worktable and high-speed servo backgauge running on precision dual linear guides and ball screws.
Intelligent Graphical CNC Control: Standard USA HACO 60 (15″ true-color multi-touchscreen with 2D graphical programming) or optional DELEM DA53T / DA58T / DA66T systems with automated bend sequencing and collision checking.
Heavy-Duty Construction & Quick-Clamp Tooling: Annealed whole steel plate welded body, 42CrMo heat-treated segmented precision punch & multi-V die tooling, and quick-acting upper clamp system for fast changeovers.
Overview & Closed-Loop Synchronous Control
The CNC Electro-Hydraulic Servo Press Brake represents the highest echelon of sheet metal bending precision and industrial productivity. Built upon an integrated whole-steel plate welded structure that undergoes high-temperature annealing furnace treatment, residual internal welding stresses are completely eliminated, guaranteeing permanent geometric accuracy and rigidity under maximum tonnage.
Featuring independent dual-axis electro-hydraulic synchronization (Y1 + Y2), both cylinders are monitored by high-precision optical linear scales that provide real-time position feedback to the CNC controller, delivering extraordinary repeatability (±0.01 mm) even during severe off-center bending operations.
Available Configurations & Style Variants
We offer flexible machine configurations tailored to different workshop aesthetic preferences and heavy-duty industrial fabrication requirements:
Style A: Classic Blue & White
Standard compact & mid-size series (e.g. 110T/3200) with ergonomic pendant arm CNC display and sliding front sheet supports.
Style B: Heavy-Tonnage Wide Bed
Heavy-duty wide series (e.g. 220T/4000) featuring deep throat depths, extended daylight openings, and reinforced bed structures.
Style C: Premium Industrial Dark Grey
High-end series (e.g. WBD-130T/3200) with laser optical safety curtains, integrated side shields, and premium industrial powder coating.
Precision Mechanics & Structural Advantages
- CNC Dynamic Mechanical Crowning: High-precision motorized wedge compensation on the lower worktable, automatically calculated by the CNC system to cancel upper beam deflection for uniform bending angles across full lengths.
- 42CrMo Hardened Segmented Tooling: Upper punches and multi-V lower dies forged from 42CrMo alloy steel, through-hardened to HRC 46–48 with surface precision grinding (accuracy within 0.02 mm).
- Rapid Clamping System: Quick-action segmented clamp blocks for one-touch upper tool loading/unloading, eliminating dropped tooling and slashing setup times.
- Integrated Hydraulic Manifold: High-performance block manifold reducing pipe connections, preventing hydraulic leaks and ensuring ultra-quiet, stable valve actuation.
