How Do You Use A Bending Brake On Aluminum Alloy?
Aluminum has a tendency to crack while bending. Properly adjusting the sheet metal bending brake will keep the aluminum alloy from cracking under the strain of bending. To set up the hand brake to perform the bend, you will need to recess the top clamping leaf of the hand brake. This will reduce the amount of strain applied to the aluminum and still allow you to get a proper bend on the aluminum alloy sheet. Mark the location of the bend on the aluminum sheet with the pencil. Avoid using a scribe or any object that will score the surface of the aluminum. Loosen the top clamping leaf adjustment bolts by turning them counterclockwise with the adjustable wrench. Place the scrap piece of aluminum vertically against the forward edge of the clamping die and turn the adjustment bolts until the rear side of the aluminum plate is 1/64 of an inch past the forward edge of the lower bending die. Tighten down the adjustment bolts with the adjustable wrench to hold the clamping leaf in position. Pus
