Product Overview
One Machine. Four Sides. Zero Repositioning.
The KAVDO Automatic Panel Bender replaces traditional press brake operations with fully automated 4-side bending. A programmable blank holder clamps the sheet while a universal bending blade forms up and down bends from all four sides — no manual repositioning required.
- Automatic 4-side bending without repositioning
- Universal blade for up/down bends in one setup
- No tooling changeover — one tool for all profiles
- Up to 80% labor reduction vs. manual bending
Why Panel Bending
Key Advantages
The automatic panel bender eliminates the bottlenecks of traditional press brake production — delivering higher throughput, consistent quality and dramatically lower labor costs.
Up to 17 Bends/Min
Automatic sheet manipulation, rotation and bending in a continuous cycle delivers throughput that is 3–5× faster than manual press brake operations — even for complex multi-bend panels.
Perfect Repeatability
CNC-controlled bending blade positioning with servo-driven axes guarantees identical bend angles and dimensions on every single panel — from the first piece to the ten-thousandth.
80% Labor Reduction
One operator can supervise multiple panel benders simultaneously. No skilled press brake operator required — the CNC handles all bending sequences, rotations and angle calculations automatically.
Zero Tooling Changeover
A single universal bending blade handles all bend angles and profiles. Switch from one panel design to another with just a program change — no physical tooling swap required.
Scratch-Free Bending
The bending blade and blank holder system forms the sheet without dragging across the surface — protecting pre-painted, brushed stainless steel and decorative-finish materials from marks or scratches.
Minimal Scrap Rate
Consistent automated bending with real-time angle compensation eliminates trial bends and operator errors. Scrap rates drop below 0.5% — saving material costs on every production run.

Core Components
Machine Structure
A fundamentally different approach to sheet metal bending — combining automated sheet manipulation with a universal bending blade for unmatched versatility and speed.
-
1
Programmable Blank Holder
Servo-controlled upper and lower blank holders clamp the sheet with adjustable force, adapting automatically to different material thicknesses and types.
-
2
Universal Bending Blade
A single CNC-driven bending blade performs both upward and downward bends at any angle from 0° to 180° — eliminating the need for multiple punch and die sets.
-
3
Automatic Sheet Manipulator
Servo-driven suction cup manipulator grips, advances, rotates and positions the sheet between each bend — enabling fully automatic 4-side processing.
-
4
CNC Controller & Software
Industrial PC-based controller with 3D graphical programming, automatic bend sequence optimization and real-time production monitoring.
-
5
Rigid Machine Frame
FEA-optimized heavy-duty steel frame with precision-machined surfaces provides structural rigidity and long-term geometric stability.
How It Works
Automatic Bending Process
From flat sheet to finished panel in one fully automated cycle — no manual handling between bends.
1
Sheet Loading
Flat sheet is loaded onto the machine table manually or via automatic feeder. Suction cup manipulator grips and positions the sheet precisely.
2
Clamping & Bending
Blank holder clamps the sheet at the bend line. The bending blade swings upward or downward to form the programmed angle with servo-controlled precision.
3
Auto Rotation
After completing bends on one side, the manipulator automatically advances and rotates the sheet to the next edge — no operator intervention needed.
4
Finished Panel Out
All four sides are bent to specification. The completed panel is released and conveyed to the output station — ready for assembly or further processing.
