In modern metal fabrication, precision, flexibility, and productivity are the key elements that define manufacturing efficiency. When working with extra-long metal sheets or large components, traditional single press brakes often face limitations in bending length and synchronization accuracy. This is where the <\/span>tandem-afkantpers<\/strong><\/a>\u2014a highly synchronized metal forming solution\u2014proves its superiority. By combining two or more press brakes to operate as one system, manufacturers can achieve longer bending lengths, improved parallelism, and unmatched forming consistency.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A <\/span>tandem-afkantpers<\/strong> is essentially two CNC-controlled press brake machines working together under a synchronized control system. These machines share the same hydraulic and electronic coordination, enabling them to bend oversized workpieces that exceed the capacity of a single machine. Operators can also use each unit independently when working with smaller parts, providing maximum versatility in the workshop.<\/span><\/p>

This combination makes tandem press brake machines ideal for industries such as shipbuilding, bridge construction, wind power, and heavy equipment manufacturing\u2014where long, thick sheets of metal must be formed with high precision and stability.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The operational principle of a tandem press brake is based on precise synchronization between the two machines. While each press brake has its own frame, hydraulic cylinders, and CNC system, they communicate seamlessly through a master-slave connection. Let\u2019s explore how this process works step by step.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The core of a tandem press brake is its <\/span>electronic-hydraulic synchronization system<\/strong>. This system ensures that both bending beams (rams) move at the same speed and maintain identical positions throughout the bending process. Linear encoders and pressure sensors monitor every motion in real-time. If one side deviates even slightly, the system instantly compensates, keeping both press brakes perfectly aligned.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A <\/span>CNC control system<\/strong> (such as Delem, ESA, or Cybelec) governs the entire process. The operator inputs bending parameters\u2014like angle, sheet thickness, and bending sequence\u2014into the controller. The CNC system then automatically adjusts hydraulic pressure and beam movement across both machines. This precise control eliminates human error, enhances repeatability, and delivers consistent bending angles along the full sheet length.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Once the sheet is positioned and clamped by the back gauge system, both press brakes begin to lower their beams simultaneously. The hydraulic cylinders apply uniform pressure across the workpiece, bending it to the programmed angle. Throughout this operation, the synchronization system continuously balances the two machines, guaranteeing a flawless bend even on workpieces over 10 meters long.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
