The electro-hydraulic servo CNC hydraulic press brake machine adopts servo motor as the power device, which meets the requirements of modern environmental protection and energy saving, and can process various metal workpieces with high efficiency and high precision. It adopts the overall welding structure and is equipped with a high-precision ESA630 numerical control system. It has the function of simulated bending and is easy to operate. The BOSCH hydraulic system imported from Germany is selected to ensure high working stability of the CNC hydrauclic press brake machine. The compensation method of the workbench can be selected from mechanical compensation or hydraulic compensation, which ensures the good straightness and bending angle of the processed workpiece. The ball screw and linear guide are selected from Taiwan HIWIN high-end configuration. The numerical control system can automatically adjust the compensation amount, which is easy to operate and has a long machine life.
