Key Technical Advantages

High-Precision Transmission

• Precision RV reducer with backlash ≤ 3 arc-min
• Ground helical gear transmission with backlash compensation
• Improved bending angle control and arc consistency

Heavy-Duty, High-Rigidity Structure

• Large-module rack and pinion transmission
• High-specification linear guideways

• Separate oil tank with a filtration system for easy maintenance

Drive System & Operating Principle

The AEK-3D 89CNC adopts a 3D CNC control system to precisely coordinate multi-axis motion and complete complex spatial bending operations.

• Feeding (Y-axis): Servo motor driven
• Pipe rotation (B-axis): Servo motor driven
• Bending (C-axis): Hydraulic drive with encoder closed-loop control
• Clamping & auxiliary actions: Pneumatic system (main clamp, guide clamp, pressure die, mandrel, etc.)

All movements are synchronized through CNC programs, ensuring high-speed response while maintaining bending stability and forming accuracy.
