Introduction
The CNC Rolling Bending Machine is an advanced metal-forming equipment designed to bend and shape metal sheets, plates, tubes, and profiles with high precision. Utilizing Computer Numerical Control (CNC) technology, this machine ensures accurate, repeatable, and complex bending operations, making it indispensable in industries such as aerospace, automotive, shipbuilding, and construction.
Key Features & Advantages
1. CNC Precision & Automation
- Programmable control system allows for exact bending angles, radii, and shapes with minimal manual intervention.
- Memory storage saves multiple bending programs for quick setup and repeat production.
- Real-time monitoring ensures consistent quality and reduces material waste.
2. Versatile Bending Capabilities
- Handles a wide range of materials, including steel, aluminum, copper, and stainless steel.
- Suitable for various shapes: plates, tubes, pipes, H-beams, I-beams, and round/square profiles.
- Capable of cold bending and hot bending (for thick or hard metals).
3. High Efficiency & Productivity
- Hydraulic or electric servo-driven systems provide powerful and smooth bending force.
- Multi-roller designs (3-roll or 4-roll configurations) enable symmetrical and asymmetrical bending.
- Fast setup and adjustment reduce downtime between jobs.
4. Robust & Durable Construction
- Heavy-duty steel frame ensures stability under high load conditions.
- Precision-ground rollers minimize deflection and ensure uniform bending.
- Anti-wear coatings extend the lifespan of critical components.
5. Safety & User-Friendly Operation
- Emergency stop buttons and safety guards protect operators.
- Touch-screen interface simplifies programming and adjustments.
- Automatic lubrication systems reduce maintenance requirements.
Applications
CNC Rolling Bending Machines are widely used in:
✔ Aerospace – Forming aircraft fuselage panels and structural components.
✔ Automotive – Bending exhaust pipes, chassis parts, and roll cages.
✔ Shipbuilding – Curving hull plates and large metal sections.
✔ Construction – Producing arched roofs, staircases, and support beams.
✔ Oil & Gas – Bending pipelines and pressure vessels.
✔ Architectural Metalwork – Creating decorative metal curves and facades.
Types of CNC Rolling Bending Machines
| Type | Description | Best For |
|---|---|---|
| 3-Roll Bending Machine | One fixed + two adjustable rolls | Simple curves, moderate precision |
| 4-Roll Bending Machine | Two fixed + two adjustable rolls | Higher precision, tighter radii |
| Variable Geometry Bending Machine | Adjustable roll positions | Complex shapes, asymmetric bends |
| CNC Plate Rolling Machine | Heavy-duty plate bending | Thick metal sheets (10mm+) |
Choosing the Right Machine
When selecting a CNC Rolling Bending Machine, consider:
- Material type & thickness (determines required tonnage).
- Bending radius & length (machine capacity should match workpiece size).
- CNC control sophistication (basic vs. advanced programming features).
- Production volume (high-speed models for mass production).
Conclusion
The CNC Rolling Bending Machine revolutionizes metal forming by combining precision, automation, and versatility. Whether for industrial manufacturing or custom fabrication, its ability to produce complex, high-accuracy bends makes it a critical asset in modern metalworking.
