The full CNC electro-hydraulic servo CNC bending machine adopts finite element mechanical analysis to ensure that the frame has the optimal size, thereby ensuring that the frame has high rigidity, high overall stability and high precision. Equipped with high-efficiency and high-precision back gauge positioning system, the back gauge is quickly positioned, and the slider runs at high speed, which greatly improves the bending efficiency. The CNC hydraulic press brake machine is equipped with imported hydraulic system, Siemens motor and oil cylinder with long service life, low noise and green bending.
