Two Machines. One Synchronized Bending System.
The SDL Series Tandem CNC Press Brake integrates two CNC press brakes through an advanced synchronization control system. Both machines operate together to process extra-long workpieces that exceed the capacity of a single press brake.
With coordinated ram movement, synchronized positioning and integrated control, the system provides an effective solution for large-scale sheet metal fabrication.
Tandem working principle
How Tandem Bending Works
The two press brakes are connected through a coordinated CNC control system. During operation, the system synchronizes ram movement and machine positioning to achieve consistent bending across the entire working length.
Intelligent Control for Synchronized Bending
The integrated CNC control system coordinates the operation of both press brakes, ensuring synchronized ram movement and consistent bending performance throughout the working length.
CNC Synchronization Control
An integrated CNC control system coordinates the operation of both press brakes, monitoring ram positions and synchronizing their movements throughout the bending process.
Ram Position Monitoring
Real-time monitoring of the slide positions of the two press brakes ensures that they move in a coordinated manner, in accordance with synchronization control requirements.
Hydraulic System Coordination
How two hydraulic systems can be integrated with CNC synchronous control to achieve coordinated movement of the rams on two press brakes.Ensure the working well
Backgauge Synchronization
The backgauge systems of the two press brakes operate in coordinated positioning, ensuring a consistent reference point for extra-long workpieces during the bending process.
