11 Ton, Chicago, Press Brake, 4' overall, 3/8" die opening, manual control

If you mean a 11-ton × 4-foot Chicago press brake, the maximum thickness depends heavily on the material and the V-die opening.

As a rough guide for mild steel:\\

If you mean a 11-ton × 4-foot Chicago press brake, the maximum thickness depends heavily on the material and the V-die opening.

As a rough guide for mild steel:

• 1/8" steel: easily within its range

• 3/16" steel: generally reasonable

• 1/4" steel: potentially, depending on the die/setup and actual tonnage

• 3/8" steel: generally beyond what I'd expect from an 11-ton machine across a 4-ft bend

If you tell me what material and thickness you're trying to bend (e.g. 1/4" mild steel, 304 stainless, aluminum) and whether you're bending the full 4 feet or a shorter section, I can calculate the approximate tonnage required.
