The selection of press brake backgauge axis is much determined by the practical use. You can select the backgauge with 1 axis (X), or 2 axis (X, R), 4 axis (X, R, Z1, Z2) or 6 axis (X1, X2, R1, R2, Z1, Z2).
Generally the press brake will be sold with one set of standard punch and dies. However, as the end user, you should select the press brake top punch and bottom die based on your practical use.
