The CNC synchronised tandem press brake consists of two bending machines, which are synchronised in a double operation. The machines can work together or independently; the front and rear pushing devices are designed for large workpieces, reducing labour intensity and improving work efficiency. The machine consists of a table slider and left and right plates. Two cylinders are mounted on the left and right side of the machine. The hydraulic system drives the ram downwards under the action of the electrical operating system. The ram is equipped with an upper die, which, when in contact with the workpiece, exerts pressure to shape the workpiece.
