Bending Camber Less System

Laser cutting and residual stress

One of the concerns that sheet metal workers may have is the camber effect. This camber phenomenon is caused by laser cutting which introduces residual stress into the material edge. This effect is particularly sensitive on long sheet metal parts, and the problem is that even after bending, the camber may still be apparent and will cause assembly problems and / or usage of the part.

Bending Camber Less System (BCLS) relieves residual stress in the material

The most common solution to get rid of the camber effect is to apply a proper level of force on the edge of the part, to release the stress. Easy to say, but not that easy to apply!

Amada has considered the problem and is now proposing a fully integrated system as an option of the HG series bending machines.

Precise and user friendly system

To ensure the best result, the force applied to release the stress has to be finely calculated. The numerical control of the machine, AMNC 3i, has the integrated calculation routines that allow it to determine this force.

Then, a mechanical mounting integrated into the lower beam of the machine makes the pressure application on the material very easy. After that, the usual bending can be done, resulting in almost no camber.

Hem bending as well…

The integrated device also makes it very easy to perform hem bending. After a pre-bend at 30°, the part is processed with the BCLS system and the hem edge is completed by applying force to the fold.
