Then, place the clamp bar back down on top of the aluminum crosswise. This limits the extent of any radius bends but makes straight, long bends much faster. STEP 3: ATTACHING THE FLAT METAL PIECES. During the bending cycle, these urethane forming pads behave like a bladder of hydraulic fluid, dissipating the press brake's downward force in all directions (see Figure 4).
