New structural concept
The GBS structure is composed by:
- 2 closed ring movable side guides;
- 1 movable top beam
- 1 fi xed lower beam.
This guarantee the structural rigidity. Movement of the two side guides: during bending phase, the top beam, the side guides and cylinders are perfectly aligned.
High and costant bending precision
The structure allows the use of ball screw guides to guarantee an extended lifetime to the machine.
Eliminating the disalignment of the pushing axis (typical on the traditinal press brakes), allows the total elimination of the structural deflections.
New structure free from encumbrances
Front and rear side of machine free from encumbrances.
Free from encumbrance, fixed and perfectly aligned with the side guides, the top beam slides on 8 ball bearing thus allowing:
- total elimination of friction;
- constant precision of movement during descent;
- constant positioning precision over entire cylinder
- high approaching speed.
