his machine is equipped with CNC numerical bending control.

Bending method
3 point bending, Normal mode

Measurement and positioning axes visible in control
Y1 and Y2 for ram positioning
X axis for backgauge depth
Z axis for backgauge lateral positioning
R axis for backgauge height

Typical positioning accuracy for this class of machine
Backgauge repeatability approx ±0.05 mm
Bending angle accuracy depends on tooling and material, typically ±0.3 to ±0.5 degrees

The control calculates bend angles based on
Material thickness
Tool geometry
