PR series hydraulic CNC bending machine



 The electric and hydraulic system controls the synchronized movemend of the two oil cylinders, thus ensures the high synchronized accuracy ,bending accuracy and repeat positiining accuracy.

 Featured with hydraulic automatic compensation system to avoid the effects on the workpiece due to the deformation of ram.The compensation is controlled by CNC system with high accuracy.

 Multi-functional backgauge which can be expanded into 6 axes ,the workpiece bending can be realized flexibly.

 The frame is assembled in one time after welding,it is processed by CNC pentahedron processing center,ensuring the rigidity and processing accuracy of the frame.

 Integrated hydraulic contrilling system decreases pipeline,thus avoids oil leakage and improves the stability if performance,  also the appearance of the machine is beautified.

 Holland Delem DA52/66T/T-3500T CNC system with the latest electric circuit and TFT display menu with high distinguish rate, is the most advanced CNC system for pressbrake.
