Explanation of CNC press brake axis

What is NC axis?

It can be simply described as — in the NC press brake machine, the motion and functional components controlled by the NC system can be referred to as the NC axis for short.

In general, the name of NC 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 configuration selection of press brake axis

The functions defined by each axis are described in the following:

X axis – Semi closed loop mechanical motion shaft of rear stopper. If equipped with X1 axis, this is the left gear finger control axis.

X1 and X2 axis – the stop finger moves forward and backward

Y axis – the piston rod of the cylinder at the left & right end of the ram moves up and down.

Y1 axis – the piston rod of the cylinder at the left end of the ram moves up and down.

Y2 axis – 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 axes – the stop finger moves left and right

V1, V2 and V3 axes – the piston rod of the convex compensation cylinder of the lower cross beam move up and down.
