High synchronization and bending accuracy is ensured due to harmonized movements of the two oil cylinders.The frame is assembled after welding, and is processed by CNC pentahedron processing center. The frame can be assembled in one time. After that the workpiece is processed by the CNC pentahedron processing center, ensuring the rigidity and processing accuracy of the frame.The integrated hydraulic control system minimizes pipe length, thus avoiding oil leakage, improving performance stability and enhancing the appearance of the machine.Equipped with the most advanced Holland Delem CNC system with modern electric circuits, a TFT display menu with high refresh rate.
