Can CNC Hydraulic Press Brakes Perform Multi-Step Complex Bending? Are Special Dies Required?

1. Can CNC Press Brakes Handle Complex Multi-Bend Tasks?

Yes, absolutely. CNC hydraulic press brakes, equipped with advanced CNC systems (e.g., Delem DA-52/DA-58, Cybelec, ESA), can precisely control axes like Y1/Y2/X/R/Z to automatically execute multi-step bending with varying angles and directions. With one programmed sequence, the machine can complete several bends without manual repositioning—ideal for complex part production.

2. What Is Considered Complex Bending?

Multi-step complex bending refers to:

• Performing multiple bends with different angles on a single sheet

• Creating Z-shaped, C-shaped, U-shaped, or box-like profiles

• Bending closed structures or components with return flanges

• Components requiring rotation and re-alignment between bends

Common applications include:

• Electrical cabinet frames and enclosures

• Kitchen equipment, elevator panels

• Machine covers and industrial sheet metal

• Window/door frames, HVAC connectors

3. Are Special Dies Necessary?

Not always. Many complex bends can be performed using standard tooling if setup is well-planned. However, in the following scenarios, specialized tooling is recommended:

• Use multi-axis back gauge (X + R + Z) for automatic repositioning

• Choose graphical control systems (DA-66T / DA-69T) for bend simulation

• Equip quick clamping systems for fast tool changes

• Customize dies according to product geometry for batch consistency
