Product Overview
The Duolek D51K CNC vertical ring rolling machine features servo motor drive (through reducer) for rolling feed, significantly reducing temperature influence while improving feed accuracy and stability. The PLC control system monitors the entire machining process according to preset parameters via touch screen interface, achieving precise control through electro-hydraulic proportional valves and encoder feedback.
The system utilizes a grating ruler to actively measure real-time ring size changes during rolling, automatically initiating rounding when preset dimensions are reached.
Advanced Features
- Enhanced precision and functionality compared to previous models
- Capable of larger rolling ratios and more complex product shapes
- Servo-controlled signal wheel actively compensates for rounded corner defects
- Redesigned HMI with one-click parameter storage and switching
- Eliminates manual mechanical adjustments - simple parameter input enables processing different products
- Operator-friendly design requiring minimal training
- Expanded loading/unloading space ideal for robotic arm integration
