Full hydraulic machines with three driven rolls with independent hydraulic motors and two bending rolls driven by massive hydraulic pistons. Roccia SR3W are developed on modern 3D CAD CAM stations to grant the structural stiffness typical of every Roccia machine and to develop the right geometry necessary to achieve a smooth and linear profile bending process.

 

The rolls are assembled on rigid electro welded frames machined on CNC boring machines to grant the precision that every Roccia machine offers even when pushed to their limit.
