Baileigh Industrial B8105 Operator's Manual page 23

Important: Liberally apply lubricant along the counterdie and the 1/2 of the
material that contacts the counter die (A) with a WD-40 style lubricant or equivalent. Do not
lubricate the bending die. Lubricating the bending die will encourage slipping of material in the
bending die.
3. The main leadscrew has a numerical counter fastened
to the shaft; this is used to display the current position.
This number should be documented for every size die,
this will allow you to return the counter die to the exact
position every time it's opened and closed. This will
ensure exact counter die position and repeatable
bends.
4. Tighten the counter die using light pressure on the three
legged handwheel documenting the position on the
counter.
5. After the material is installed, bending can take place.
6. Turn on the power switch.
7. Set the desired bend angle on the bend angle controller.
8. Keep hands away from the bending zone.
9. Press the right foot pedal switch to rotate the die forward. Keeping the foot pedal activated,
visually watch the digital display. The cylinders will stop when the forming die rotates to the
desired bend angle as shown on the controller. The 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.
10. If the bend requires more degrees. The controller will need to be set at a higher degree
number. 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. 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 machines degree 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.
