SECTION BENDING MACHINE MC650
5. INSTRUCTIONS FOR USE
5.1. Bending principles
- The motor of the bending machine is controlled from the control panel.
- The radius of the curve is controlled by acting on the push buttons on the control panel, adjusting the
height of the two lower rollers.
- There is an emergency button on the panel.
- You can insert the material into the machine from either side. Use the position buttons to adjust the height
of the lower rollers and thus adjust admission of the material. By means of the limit switches, we can posi-
tion the final point of the lower rollers, separately, enabling you to obtain great position repeatability.
- To adjust the alignment of the material, it is necessary to modify the distance between the straighteners and
the work surface. This is done by acting on the nuts located at the back of the machine. These straighteners
guide the material so as to minimise lateral deformation. (The rollers of the straightener must press gently
against the section to be curved)
- In the event of not obtaining the proper results, the position of the guide rollers for deformation must be
adjusted.
- The roller mounting nuts must be tightened by manual force only .
