For any types of manufacturing task, Factory Press WordPress Theme is the best choice.
Our VR-3 series variable-geometry plate rolls, which really operates more like a press brake than a traditional plate roll, makes not only extreme rolling possible, but much simpler. The two lower rolls are very similar to an adjustable V die, and the top roll can be operated like the ram of a press brake. That’s why we called his machine VR-3. They are suitable for medium and thick plate bending.
The PLC Electronic balancing system ensures the synchronous operation of the bottom and side rollers of the machine. This process is provided by PLC and touch operator panel which controls 6 axes. In addition, ease of use and time saving are provided by the ability to program up to 5 set points of the previously experienced bending values.
NC control system, in addition to the PLC control system, has the property to work manual, teach-in and automatic modes of operation. In manual mode, the use of all functions are provided by the operator. In teaching mode for the operator to do all the steps are recorded respectively. In automatic mode all recorded movements are repeated, respectively by the machine.
