Bending Using Main Degree Wheel
1. After the material is installed, bending can take place.
2. Turn on the power switch
3. Keep hands away from the bending zone.
4. Press the right foot pedal switch to
rotate the die forward. Keeping the foot
pedal activated, visually watch the
degree dial (A). Hold until the desired
degree is displayed on the large
degree dial, bumping along as needed.
Material will need to be bent past
desired degree as all material has
some degree of "springback". This
varies by material and can even vary
between the same grades of material.
5. If the bend requires more degrees.
Increase the degrees by further
activating the forward foot pedal
switch. This allows the operator to
gradually reach a bend angle, on the
first set up piece.
6. To determine the amount of springback for a certain material, it is necessary to bend a
sample piece. Using a framing square or the like, bend a piece of material until a perfect 90°
bend is achieved, when checked with a square. At that point, document the main degree
dial's (A) position. For example, to a achieve a 90° on the piece in the picture, 105 degrees
was the total bend amount or 15 degrees of springback. Now you can add 15 degrees to any
nominal bend angle to achieve accurate results for this material.
