The press force acts upon the machine bed during the bending process (action).
This leads to a counter-force arising in the C-frame of the side housings (reaction).
Deflection occurs, despite the robust construction of the side housings. This is the reason why the upper tool penetrates less deeply into the lower tool than the hydraulic cylinders travel on the stroke
by changing the material analysis, material hardness from one side to other side, changing the lengths and having holes in part of bend, while no holes on the other side, it leads to different deflection from one side to the other side of the body.
In order to have a precise bending and accuracy, we should compensate and control this deflection.
Some expensive devises can do it by using sensor, encoders and… and applying the deflection compensation on controller, but it is too expensive.

The Frame Name Is Hexa-C and under patent of Adira.
Adira Hexa-C Patent
The upper beam has guided and separated from the body so always will move straight on the lower beam.
