The Difference between Hydraulic NC Press Brake and CNC Hydraulic Press Brake Machine

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.

One set of main hydraulic system

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

Mechanical torsion bar for ram balance  (manually adjustable)

The grating ruler at two sides for two cylinders’ balance (easy adjustment through the controller)

Stop finger can manually adjust up and down

Back gauge can extend to more axes: X1, X2, R1, R2, Z1, Z2
