CNC Servo Busbar Bending Machine Key Features
Engineered for High-Precision Busbar Bending
Closed-Frame Bending Structure
The closed-frame structure provides high rigidity and stable force distribution, helping maintain consistent bending accuracy under high loads.
Tooling for Different Bend Requirements
Flat and vertical bending tools accommodate different busbar shapes and radii. Optional twist tooling is available; tooling selection depends on the material and drawing.
Programmable CNC Positioning
The CNC stop supports controlled workpiece positioning, helping reduce repeated manual measurement between bends. The specified stop positioning accuracy is ±0.15 mm.
Beckhoff CNC Control System
Beckhoff control and the machine’s CAD/CAM software support programmable bending operations. The operator interface brings workpiece data and bending sequences together on screen.
