What Is the LB-CNC Electro-Hydraulic Servo CNC Press Brake?
The LB-CNC is a synchronized CNC press brake that uses electro-hydraulic servo control to manage ram movement and bending accuracy. The Y1 and Y2 axes are controlled independently to maintain synchronization during bending, while the CNC system calculates bending pressure, angle correction, back gauge position and crowning compensation according to the selected program.
Compared with conventional hydraulic press brakes, an electro-hydraulic servo CNC press brake provides better repeatability, easier operation and higher bending accuracy for industrial sheet metal production.
Buyer Pain Points and LB-CNC Solutions
Customer Challenge | LB-CNC Solution |
|---|---|
Bending angle is inconsistent | Y1/Y2 synchronized control improves ram positioning accuracy |

Operators spend too much time calculating bending data | CNC system supports automatic calculation of pressure, opening distance and unfolding length |
Different parts need different back gauge movement | Optional 3+1, 4+1, 6+1 and 8+1 axis configurations support different bending complexity |
Machine frame deformation affects accuracy | Integral welded and machined structure improves rigidity |
Need reliable production for sheet metal workshops | ANSYS finite element analysis supports structural strength and long-term machine stability |
Key Advantages
Electro-Hydraulic Servo Synchronization
The LB-CNC uses electro-hydraulic servo control to synchronize the Y1 and Y2 axes, helping the ram move accurately during bending. This improves bending repeatability and is especially important for long workpieces and high-precision sheet metal parts.
Rigid Welded Machine Frame
The machine body adopts an integral welded and machined structure. Key structural components are analyzed with ANSYS finite element analysis to improve machine rigidity, reliability and overall precision.
Professional CNC Control System
The CNC system can be configured with DELEM from the Netherlands, ESA from Italy or CYBELEC from Switzerland. It supports graphic bending programming, angle correction, automatic pressure calculation and back gauge control.
Automatic Crowning Compensation
The CNC system automatically calculates worktable deformation compensation during bending. This helps maintain bending accuracy across the full working length, especially for longer sheet metal parts.
Flexible CNC Axis Options
The LB-CNC supports different axis configurations from 3+1 axes to 8+1 axes. Users can choose the required back gauge and servo-driven axes according to part complexity, bending accuracy and production needs.
Wide Material Compatibility
The machine can bend stainless steel, carbon steel, aluminum, copper, brass and alloy sheet materials. The suitable model should be selected according to material type, sheet thickness, bending length and required bending force.
CNC Axis Options
Y1, Y2 and V are essential axes for every CNC bending machine. Additional back gauge and servo-driven axes can be selected according to the parts being processed.

Material Type | Stainless steel and high-strength steel require higher bending force |
Sheet Thickness | Thicker sheets require larger nominal force |
Bending Length | Longer workpieces require longer workbench and better crowning compensation |
Bending Accuracy | Higher accuracy may require more CNC axes and better back gauge control |
Part Complexity | Complex parts may require 4+1, 6+1 or 8+1 axis configuration |
Production Volume | High-volume production benefits from faster CNC setup and repeatable programs |
Tooling Requirement | Different bend shapes require suitable punch and die selection |
