          The table shows the average capacity (max force, t) for different pressbrake sizes (bending line, m). E.g. a 3-metre pressbrake can usually exert 100-200 tons of force which makes it suitable for 20 mm steel with a bending line of 1.5 m (check the calculator on the left).

          General bending force formula

          c – constant from formula 2
          Rm – material tensile strength (N/mm2 )
          V – V-width of bottom die (mm)
          L – bending length (m)
          t – sheet thickness (mm)
