What is press brake axis? #
Press brake axis can be simply described as:
In the press brake machine, the motion and functional components controlled by the controller can be referred to as the press brake axis for short.
In general, the name of press brake axis is named according to the position where the spatial position of each axis in the machine conforms to the coordinate system, while some other motions and functional components are named according to conventional usage or international customary standards.
Then, a CNC press brake machine is configured with several axes, which are generally reasonably configured according to the process requirements of the user’s workpiece.
Setting and selection of press brake axis #
The functions defined by each press brake axis are described in the following:
Semi closed loop mechanical motion axis of rear stopper. If equipped with X1 axis, this is the left stop finger control axis.
X1 and X2 axis
The stop finger moves forward and backward
The piston rod of the cylinder at the left & right end of the ram moves up and down.
The piston rod of the cylinder at the left end of the ram moves up and down.
The piston rod of the cylinder at the right end of the ram moves up and down.
R, R1, R2 axis
The stop finger moves up and down.
Z, Z1 and Z2 axis
The stop finger moves left and right.
The piston rod of the convex compensation cylinder of the lower cross beam move up and down.
What does 3+1, 4+1, 6+1, 8+1 axis mean? #
First of all, we need to know that the “+1” axis refers to the press brake crowning axis, that is, the V axis.
And the Y1&Y2 axis refer to the up and down of the left and right oil cylinder separately.
Then, it is simple to understand the 3+1, 4+1, 6+1, 8+1 axis and the details are as follows:
3+1 axis: Y1, Y2, X, +V
4+1 axis: Y1, Y2, X, R, +V
6+1 axis: Y1, Y2, X, R, Z1, Z2, +V
8+1 axis: Y1, Y2, X1, X2, R1, R2, Z1, Z2, +V
