To remove cylindrical shaped workpieces:
1. Loosen bolt (M, Figure 13)
2. Rotate the screw (N
1
, Figure 30) toward the
rear of the machine to release the roll catch
(N
2
).
3. Carefully grasp upper roll and swing out the
end.
Grasp the upper roll firmly,
to prevent it falling out of the machine.
4. Slip the workpiece off the end of the roll.
5. Re-install the upper roll, and rotate the
screw (N
1
) back toward the front to secure.
Flat Rolling
Softer metals (copper, aluminum, etc.) can be
processed through the slip roll machine to
straighten, flatten, or reduce their thickness.
Simply adjust the upper press roll for thickness,
lower the idle roll all the way down, and feed the
workpiece through (Figure 14).
NOTE: The idle roll will not descend completely
out of the path of the workpiece; thus, there may
be a slight bend in the workpiece. By flipping the
workpiece over and re-feeding it, this bend can
be minimized.
Forming a Radius
1. Adjust the upper press roll as needed.
2. Insert the workpiece from the front.
3. Operate the lever; when the material
reaches the point where the radius is to
begin (a, Figure 15), stop the machine and
raise the idle roll an equal amount on each
end to achieve the desired bend.
4. Re-start the rolls and continue until the bend
is completed (b, Figure 15). Support the
workpiece as it exits the machine.
5. Make further passes if needed, along with
incremental idle roll adjustments.
Forming a Tube
1. Adjust the upper press roll as needed for
workpiece thickness.
2. Feed the workpiece into the machine. As it
nears the end (a, Figure 16), stop and
reverse direction (b, Figure 16).
3. Make further passes if needed, along with
incremental idle roll adjustments.
