NC hydraulic press brake /bending machine limited for 2 axes only: X+Y

When you want to bend 90 degrees for a 3mm thick plate,

1. Testing a plate in Y=88mm, maybe you got 89 degrees, or maybe 91degree. This need to test some sheets to get what you want.

2. When you change a thickness, material or length or V-die, etc., each factor changed, you have to test again some sheets, so totally you have to test many sheets plate to get what you want, then make a record list.

CNC press brake /bending machine /folding machine is 4 Axis:

Y1+Y2+X+R, it can extend more ,such as 5/6/7/8/9/10 axis 

When you want to bend 90degree for a 3mm thick plate,

1. You put 3mm thick, put 90degree into the controller directly, choose the right tooling, test a bending, you may get 89 degrees or 91 degrees, then just amend several parameters in the controller.

2. Then do a second bending, you will get exactly what you want.

3. So this work is calculated by the controller.

NC controllerCNC controller

One set of main hydraulic system


nc 1


One set of the main hydraulic system + two sets of servo proportional valves (on the top of the left and right cylinder)

cnc 1

Mechanical torsion bar for ram balance  (manually adjustable)

nc 2
