Servo-Driven CNC Aluminum PVC Bending Machine

• Multi-materiaThis CNC Aluminum & PVC Profile Bending Machine is engineered for high-precision arc forming of architectural profiles used in curtain walls, facades, arch windows, and PVC window frames. Equipped with a 3-roller synchronized bending system and servo-driven control, it delivers smooth, distortion-free curves with ±0.5mm bending accuracy. Compatible with both aluminum extrusions and PVC/UPVC profiles, the machine supports multi-radius bending in a single setup, significantly improving production efficiency while reducing material waste. CE certified and fully customizable, it is the ideal solution for modern architectural profile fabrication.l compatibility: The CNC Aluminum PVC Profile Bending Machine bends aluminum, PVC, UPVC, thermal break, stainless steel, and copper profiles.

How It Works

1. Profile Loading

Aluminum or PVC profiles are placed into the feeding guide and securely clamped to prevent slipping or twisting during the bending process.

2. 3-Roller Synchronized Bending

The machine adopts a three-roller synchronized drive system:

Top driving roller feeds the profile forward

Two side forming rollers move along CNC-controlled paths to apply uniform pressure

This synchronized movement ensures consistent arc formation without surface damage, wrinkles, or profile distortion.

3. Servo-Driven Precision Control

Servo motors control roller positioning in real time, providing accurate feedback and repeatable bending performance. The CNC system automatically compensates for material spring-back, ensuring the final radius matches the programmed value.

4. Multi-Radius & Complex Curve Programming

Operators can program multiple bending radii, arc segments, and full circles directly from CAD drawings. The system supports continuous bending of complex curves without manual repositioning.

5. Repeatable Mass Production

Once the bending program is saved, the machine executes identical bending cycles with high consistency, making it suitable for both custom architectural projects and high-volume production.

Process Flow:

Profile Loading → CNC Program Input → 3-Roller Synchronization → Servo Positioning → Multi-Radius Bending → Finished Curved Profile
