Technical Specifications of Large Diameter CNC Flanging Machine

What Is a Large Diameter CNC Flanging Machine?

A large diameter CNC flanging machine is specialized equipment used to form accurate flange edges on oversized cylindrical and conical metal components through controlled spinning and forming processes.

During operation, the workpiece is securely clamped and rotated while CNC-controlled forming rollers gradually shape the edge into the required flange profile. Compared with traditional welding or manual forming methods, CNC flanging provides better repeatability, improved dimensional accuracy and reduced secondary processing.

The BXFBJ2000-III is developed for manufacturers requiring stable flange forming performance on large industrial components.

Large Diameter Flanging Capability

The BXFBJ2000-III is designed for large-size components that require reliable forming quality and consistent flange dimensions.

• Large industrial fan barrels

• Fan inlet collectors

• Axial fan housings

• Centrifugal fan components

• Large ventilation ducts

• Pipe flange sections

• Conical transition components

• Environmental equipment shells

Integrated Flanging, Beading, Punching and Trimming

One of the main advantages of the BXFBJ2000-III is its integrated multi-process capability. Multiple forming operations can be completed without repeatedly removing and repositioning the workpiece.

• Flanging: Creates accurate flange edges for connection and assembly.

• Beading: Improves component strength and structural rigidity.

• CNC Punching: Creates precise bolt holes and mounting patterns.

• Trimming: Provides clean and consistent edge finishing.

This integrated production method helps reduce manual handling and improves production consistency for large diameter components.

2. CNC Forming

The workpiece rotates while forming rollers gradually shape the metal edge according to the programmed forming path.

3. Flange Formation

The CNC system controls roller movement to achieve consistent flange width, angle and profile.

4. Additional Processing

Beading, punching and trimming operations can be completed according to production requirements.

5. Final Inspection

The finished component is checked for dimensional accuracy and flange quality before moving to the next production stage.
