Try using the tool with a sample piece of metal to get a feel for how it operates. Place the
material in the middle of the jaw box and step down on the foot pedal to form the metal. Work
the leading edge of the material first to break down the initial resistance of the metal. Move the
metal back and forth until the desired radius is obtained. You can control the pressure exerted
on the metal by how tight the gap is set between the jaw and how long you hold down the foot
pedal.
The jaws have fine toothed edges to hold the piece part in place. Marks left on your piece part
can be removed with either an abrasive cloth or a wheel for appearance.
MATERIAL SELECTION
When selecting materials keep these instructions in mind:
•
Material must be clean and dry. (without oil)
•
Material should have a smooth surface so it processes easily.
•
Dimensional properties of material must be consistent and not exceed the machine capacity
values.
•
Chemical structure of material must be consistent.
•
Buy certificated steel from the same vendor when possible.
UNDERSTANDING SPRINGBACK
Springback, also known as elastic recovery, is the result of the metal wanting to return to its
original shape after undergoing compression and stretch. After the bending leaf is removed from
the metal and the load is released, the piece part relaxes, forcing the bent portion of the metal to
return slightly to its original shape. The key to obtaining the correct bend angle is to over bend
the metal a little and allow it to spring back to the desired angle. All metals exhibit a certain
amount of spring back.
CAUTION:
It must be determined by the customer that materials being
processed through the machine are NOT potentially hazardous to operator or
personnel working nearby.
