4000mm Hydraulic Press Brake with E21, 400-ton plate bending machine from China for sale.
● The whole welded machine structure achieves high rigidity; the machine is designed by ANSYS software which can ensure the reliability and precision of the press brake.
● The motors for Back-gauge and ram stroke are controlled by inverter, which can achieve high positioning accuracy of the Back-gauge and ram by changing the frequency and voltage of motor.
● X axis (Back-gauge) and Y axis (Ram stroke or cylinder stroke) can be programmed by the controller, which can make the bending job easy.
● Side and rear metal safety guard meets European safety standard.
● Hydraulic overload can be protected by overflow valve, System pressure can be regulated by pressure switch easily.
● Foot switch with emergency button can stop the machine immediately when accident happens.
