The electro-hydraulic servo CNC bending machine is equipped with imported servo motors, which can efficiently drive the movement of the back gauge system through the servo motors, with stable functions, which can effectively reduce machine tool noise and save energy. The CNC hydraulic press brake machine is equipped with a mechanical deflection compensation worktable, which can effectively compensate according to the length, thickness and bending angle of the bending workpiece, and automatically calculate the compensation amount according to the processing program of the system, so as to ensure the bending of each workpiece are with high bending accuracy. Equipped with Delem DA66T CNC system, it can automatically calculate the bending pressure. The CNC bending machine is equipped with table compensation, which greatly improves the bending accuracy, and is especially suitable for processing high-precision products such as thin plates and stainless steel plates.
