Back Gauge Configuration

Select a back gauge configuration. The "+1" refers to the mechanical crowning device included on all Hudong CNC press brakes.

2+1 Axis

X · Y

Y — BeamX — Depth

Standard configuration. X-axis controls depth; Y-axis controls beam. Most economical option.

4+1 Axis

X · Y1·Y2 · R

Y1/Y2 — SyncX — DepthR — Height

Adds R-axis (finger height). Supports multi-step bending sequences. Most popular choice.

6+1 Axis

X · R · Z1·Z2

X — DepthR — HeightZ1/Z2 — Lateral

Adds Z1/Z2 lateral movement. Enables complex multi-reference parts without repositioning.

8+1 Axis

X1·X2·R1·R2·Z1·Z2

X1/X2 — IndependentR1/R2 — IndependentZ1/Z2 — Lateral

Dual independent arms. Maximum flexibility for asymmetric parts and full automation.
