Electro-Hydraulic CNC Press Brake- 4-6+1 Axis


LIANGJI
Performance Series | 4-6+1 Axis Electro-Hydraulic CNC Press Brake
The Ultimate Balance of Industrial Precision and Cost-Efficiency
LIANGJI Performance Series is a robust and highly versatile 4-6+1 axis electro-hydraulic CNC press brake, engineered with an impressive array of high-end features and customization options.
Delivering competitive pricing without sacrificing heavy-duty reliability, it comes standard with the intuitive CT16pro (4+1 Axis) or the advanced DELEM DA53T 2D graphical controls. Customers can also easily upgrade to the DE69T/58TX system for full 6+1 axis servo-driven precision, or choose from a versatile range of alternative CNC controllers, including the Spectrum S680 and ESA S630. Backed by a tempered frame and floor-type boring precision, it ensures years of deformation-free operation.
When reliability meets advanced electro-hydraulic synchronization, the Performance Series stands as your premier solution for efficient sheet metal processing.

FEA & Stress Analysis
Engineered using advanced SOLIDWORKS CAE, every LIANGJI machine frame undergoes rigorous Finite Element Analysis. By simulating complex stress and heavy loads, we guarantee maximum structural rigidity and zero deformation over years of operation.

Ultimate Structural Rigidity
Vibratory Stress Relief & High-Temperature Furnace Tempering
Built for decades of heavy-duty operation. Every LIANGJI machine frame undergoes advanced Vibratory Stress Relief (VSR) to eliminate internal welding stresses. Combined with a strictly tempered ram, this dual-treatment guarantees lifetime dimensional stability, zero deformation, and consistent bending precision.

Precision Anti-Deflection Tempered Plate
· Strategic Placement: Installed beneath the ram to directly absorb stress.
· High-Temperature Tempered: Exceptional rigidity and wear resistance.
· Deform-Resistant: Effectively minimizes ram deflection under heavy loads.
· Extended Lifespan: Protects critical surfaces, reducing maintenance costs.

CT16-Pro Touch CNC System
- Smart 2D/3D HMI: 15.6″ HD multi-touch screen with intuitive graphical programming for rapid setup.
- Multi-Axis Mastery: Standard multi-axis control, seamlessly expandable to 12 axes for robotic integration.
- Closed-Loop Precision: Electro-hydraulic servo core ensures absolute synchronization and pinpoint accuracy.
- Intelligent Database: Built-in tooling and material libraries with automatic crowning compensation.
- Anti-Collision Logic: Smart algorithms protect your tooling and ensure safe, error-free operations.

LIANGJI Center-Drive™ Precision Backgauge System
- “In-Line” central ball screw and HIWIN/TBI dual guides on X, R-axis.
- 10mm thick, 200mm wide heavy-duty beam for zero torque deflection.
- Rapid Axis X speed: 400 mm/s | Axis R speed: 200 mm/s.
- Guaranteed mechanical accuracy of ± 0.02 mm.
- Fully enclosed R-axis with customized accordion shielding.
- Sliding Z1, Z2-axis on linear guides with heavy-duty stop fingers.
- Back gauge finger: medium frequency quenched, hardness HRC 55-60.

CNC Mechanical Crowning System
- Erfect Angles Every Time: The CNC-controlled crowning motor automatically adjusts the lower table’s wedge system to compensate for frame deflection during heavy bending.
- Consistent Precision: Ensures the bending angle remains absolutely identical across the entire length of the sheet metal, eliminating the “canoe” effect.

High-Precision Tooling Configuration
- Fast Clamps: Ergonomic red levers for rapid, wrench-free upper tool changes.
- Standard Tooling Setup: Equipped with a 150mm height upper punch and a V8/V12 double-V lower die.
- Anti-Rust Treatment: Sandblasted and black-oxide treated to ensure exceptional corrosion resistance and longevity.
- Bespoke Tooling Solutions: Fully customizable punches and dies manufactured strictly according to your specific bending requirements or technical drawings.
- Extreme Durability: Hardened tool steel ensures precise bending on tough materials.
