A grid bending machine is provided for bending a workpiece. The machine includes first and second guides having inner surfaces defining a cavity therebetween. A stationary anvil is mounted to the first and second guides. A first die is releaseably connected to the stationary anvil. A body is disposed in the cavity and is movable between a first position release position and a second bending position. A second die is releaseably connected to the body and is aligned with the first die. The second die is axially spaced from the first die with the body in the release position and is adjacent the first die with the body in the bending position.
