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
Press force
Bend allowance


Main intention of use

The primary purpose of this machine is precision bending of sheet metal parts.

Typical operations
Straight bends
Box shapes
U bends
Complex multi step formed parts

It is designed for medium to heavy gauge sheet metal over long bending lengths.
