How to adjust sheet metal brake.

Adjust the nose gap by turning the large brake nose gap adjustment knobs at the rear of the upper jaw to achieve its proper alignment. For clamp adjustment here are some suggestions. Adjust by means of clamping handle adjusting nuts as shown. Release clamping handles sufficiently to allow material to pass between the top leaf and the bed.

To tighten clamping pressure release the top nut and tighten the bottom nut. Set the clamping pressure so that it is enough to keep the material from slipping during a bend. Check clamping pressure by placing test strips in the brake about 3 or 4 inches away from each end of the brake. Radius set back refers to the distance between the leading edge of the clamp and the inside edge of the apron.

Figure 5 the perfect setting is obtained when the bending leaf is held up to the angle of the finished bend and there is one material thickness between the bending leaf and the nose radius piece. Tighten down each casting with the allen wrench until it is just tight enough that you can t pull it out. Check end to end clamp alignment by placing a test strip. Adjust the brake cut five cards of aluminum coil stock and slide them in at each casting.

Do this on both sides of the brake. Adjust top leaf with top adjustment on side that is overbending.
