Standard press brakes cannot meet precision requirements
For more stable angles, more complex workpieces and higher repeatability, electro-hydraulic servo CNC control provides a stronger platform for precision sheet-metal production.

Production Challenges
What Bending Problems Can It Solve?
Start with the real workpiece, production rhythm and consistency requirement before selecting axes, controls and tooling.
02
Frequent job changes require faster setup
CNC programs, stored bending steps, back-gauge positioning and a confirmed tooling plan reduce repeated manual measurement and setup work.
03
Long workpieces need better angle consistency
A rigid frame, suitable tooling and an optional crowning system can help manage deflection and improve consistency along the bending length.
04
Complex parts need multi-axis back gauge support
Optional multi-axis back gauges provide more positioning flexibility for multi-step bends, irregular parts and repeat batch production.
05
Production needs a higher-level CNC solution
Compared with basic NC or torsion-bar machines, this platform better serves customers needing Y1/Y2 closed-loop control, more axes and demanding production workflows.

06Brass Sheet
07Thin Metal Plate
The suitable bending thickness depends on material strength, bending length, V-die opening, bending angle, tooling and machine tonnage. Please confirm your material and bending requirement before quotation.
Bending Process
From Flat Sheet to Precision Bent Part
A seven-step process view connects prepared sheet, CNC setup, controlled forming and downstream manufacturing.
01
Sheet Cutting
Cut the sheet to the required size by fiber laser cutting machine, shearing machine or other cutting equipment.
02
Tooling Selection
Select suitable punch and die according to material, thickness, V opening, bending angle and part drawing.
03
CNC Program Setting
Set bending steps, back gauge positions, stroke and production data through the CNC controller.
04
Back Gauge Positioning
Use CNC-controlled back gauge axes to position the sheet for repeated and complex bending tasks.
05
Servo-Hydraulic Bending
The electro-hydraulic servo system controls ram movement to complete the bending process.
06
Angle Checking
Check the bending angle and adjust tooling, crowning or program settings when needed.
07
Next Process
Continue with welding, riveting, assembly, surface treatment or final product manufacturing.
Closed-loop ram control
Electro-Hydraulic Servo Synchronization
The machine uses CNC control, proportional servo valves, hydraulic cylinders, linear scales and sensor feedback to coordinate the left and right cylinders through independent Y1/Y2 axes.
- Closed-loop feedback detects ram position and supports continuous synchronization correction.
- Independent Y1/Y2 control provides a more controllable platform for asymmetric and complex workpieces.
- It is better suited than mechanical torsion-bar synchronization to precision, repeated and multi-step bending requirements.
- Final performance still depends on the workpiece, tooling, compensation, setup and selected machine configuration.
Programs, axes and production data
Advanced CNC Control for Complex Bending
The CNC system can coordinate bending steps, Y1/Y2 ram movement, back-gauge positions and compensation functions according to the selected controller and axes.
- Multi-step programs support complex parts, repeated orders and frequent job changes.
- Program storage reduces repeated manual measurement after a process has been confirmed.
- Graphical programming and 2D or 3D simulation depend on the selected controller model.
- Controller selection should follow part complexity, operator workflow and required axes.
Flexible part positioning
Multi-axis Back Gauge for Accurate Positioning
Back-gauge configuration directly affects positioning flexibility. Basic arrangements cover recurring straight bends, while additional axes support more complex flanges and part geometries.
- X-axis controls the primary positioning depth for recurring bends.
- R-axis height movement can support different tooling and flange positions.
- Z1/Z2 fingers can be positioned for irregular or wider workpieces.
- Ball screws, linear guides and servo drives support controlled back-gauge movement depending on configuration.
Angle consistency starts with process matching
Crowning and Tooling Matter
Long workpieces can be affected by frame and tooling deflection. Crowning and the correct punch-and-die combination help manage angle consistency across the bending length.
01
V-die opening affects bending force, minimum flange size and bending quality.
02
Stainless steel usually requires higher bending force than mild steel under comparable conditions.
03
Special profiles may require custom tooling and a drawing review.
04
Mechanical or CNC crowning should be selected from bending length, material, tooling and quality requirements.

Buyer Questions
Frequently Asked Questions
Answers use the current product information and keep controller, axes, tooling and compensation details configuration-dependent.
01What is an electro-hydraulic servo CNC press brake?
It is a sheet-metal bending machine that uses Y1/Y2 electro-hydraulic closed-loop control to coordinate both sides of the ram while a CNC system manages bending programs, back-gauge positions and configured machine functions.
02What materials can this machine bend?
It is commonly used for mild steel, stainless steel, galvanized sheet, aluminum and copper. Capacity depends on material strength, thickness, bending length, tooling and machine tonnage.
03What is the difference between electro-hydraulic CNC and torsion bar CNC press brakes?
A torsion-bar CNC press brake uses mechanical torsion-bar synchronization and suits standard CNC bending. The electro-hydraulic machine uses independent Y1/Y2 feedback control and is better suited to more axes, complex parts and demanding consistency requirements.
04What is the difference between an NC press brake and an electro-hydraulic CNC press brake?
An NC press brake is intended for basic and regular bending. An electro-hydraulic CNC press brake provides closed-loop ram control and broader axis and programming options for complex parts and frequent job changes.
05Is this machine suitable for precision sheet metal fabrication?
Yes. It is commonly selected for precision sheet metal, cabinets, enclosures, stainless-steel products and equipment housings, with the final configuration confirmed from part drawings and production requirements.
06Can it bend stainless steel?
Yes, provided tonnage and tooling are selected for the stainless-steel grade, strength, thickness, bending length, V-die opening and required angle.
07How do I choose the right tonnage?
Provide the material, thickness, bending length, V-die opening, angle and part drawing. An engineer should confirm tonnage and safety margin against the real application.
08What back gauge axes should I choose?
Basic positioning is suitable for regular bends. Parts with multiple flange heights or irregular geometry may benefit from X, R, Z1/Z2 or additional axes, confirmed from drawings.
09What controller can be used on this machine?
Delem, ESA, Cybelec and other CNC system options may be available. The exact controller and graphical functions depend on the final axis configuration and order.
10Does this machine need a crowning system?
Crowning is commonly considered for long workpieces or demanding angle consistency. The method should be selected from bending length, material, thickness, tooling and quality requirements.
11Can the machine be customized?
Tonnage, bending length, controller, back-gauge axes, voltage, tooling, safety configuration, clamps and crowning method can be reviewed before quotation.
12What information should I provide before quotation?
Provide material, thickness, bending length, angle, part drawings, production quantity, voltage, controller and back-gauge requirements, tooling needs and destination country or port.
