CNC PRESS BRAKE BENDING SERVICE

V-grooving is a precise metal processing technique used to create sharp bends or folds by cutting a V-shaped groove along the bend line of a metal sheet. The groove reduces the material thickness at the bend point, allowing for a cleaner, sharper, and more accurate fold, especially on thicker or rigid materials.

Purpose of V-Grooving:

Achieves tight internal bend radii that can’t be done with regular press brake bending.
Enhances the aesthetic quality of architectural or decorative metalwork by producing crisp, sharp corners.
Allows bending thick sheets without distortion or cracking.
Reduces spring-back during bending, improving accuracy.

Common Applications

Materials Suitable

Benefits

Architectural panels & facades (e.g., elevator panels, column covers)
Furniture with sharp bends and modern finishes
Signage and decorative trims
Custom enclosures or casings for electronics
Kitchen equipment, especially when using stainless steel

How It Works:
1. A V-shaped groove is cut into the back side of the metal sheet using a CNC V-grooving machine.
2. The depth is carefully controlled, leaving a thin layer (typically 0.3–0.8 mm) uncut.
3. The sheet is then bent along the groove using a press brake or manual bending.
4. The result is a sharply defined outside corner with a minimal bend radius.
