Shoulder flexion and or opening is a physical phenomenon that can
never be avoided.
So you need a shoulder flexion control system to correct this problem.
The two side shoulders of the press brake go against a bending
resulting from the natural effort and tend to open in the hollow area.
This deflection increases the distance between the top beam and
the bench, thus generating an incorrect position.

The G-FLEX system of the LAG ORIGINAL MACHINERY controls this
shoulder opening thanks to a measuring device that communicates
in real time with the hydraulic system.

The system calculates in real time the real height at which
the punch is located, regardless of the deformations.
