10.0 Operation
10.1 Roll Adjustment
(Figure 1 identif ies m ac hine elem ents.)
Four adjustment screws (two in front and two in
the rear) have been built into the left and right
side frames.
The two front adjusting screws enable the
operator to raise or lower the pinch roll, so that
the correct gap between the stationary and
pinch rolls may be obtained to feed the desired
stock into the machine.
The rear adjusting screws raise or lower the idler
roll which determines the degree of bend in the
stock that is being fed through the machine. The
right and left side frames are each equipped with
a scale to aid the operator in determining.
To adjust the rolls for material thickness:
1. Insert the material between the rolls from the
front of the machine and raise the pinch roll
until the material fits tightly.
2. Raise the idler roll equal amounts at each
end, to desired position for the bend.
No exact formula can be followed when making
these roll adjustments because material "spring
back" varies with the kind of material being
formed. Only by test forming several pieces can
the correct adjustments be obtained. Also, keep
in mind that it is much easier to re-pass material
to make a smaller radius than it is to attempt to
increase a radius that was made too small.
Rolls must be adjusted exactly parallel or the
material will spiral during the rolling process.
Measure each end of the opening with calipers if
greater precision is required.
NOTE: Deliberately setting the rolls non-parallel
can be used to make cone shapes.
11.0 Forming the Workpiece
The rolls present a pinch
point and/or crush hazard. Do not place
hands in close proximity to the rolls while
operating.
11.1 Material Size Considerations
To determine the approximate length of material
needed for a desired size tube, use the following
formula:
where
and
For example: To find the length of material
needed (C) to form a tube 4" in diameter,
multiply 3.1417 by 4". Result: 12.5667" is the
circumference of approximate length of material
needed. Cut several pieces of material to this
length for a forming test run. Material may have
to be lengthened or shortened depending upon
results of the test run.
If the workpiece is large, make sure it receives
proper support as it exits the slip roll machine.
11.2 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 pinch roll for thickness, lower
the idler roll all the way down, and feed the
workpiece through (Figure 5).
NOTE: The idler 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.
DC
is the circumference,
C
equals 3.1417
is the diameter.
The stationary, or top, roll is secured at its left
end to the gear side of the machine with the cap
screw and jam nut (see Figure 1). These can be
adjusted if needed.
10.2 Foot Pedal Operation
The shrouded foot control has pedals for instant
forward or reverse motion.

Figure 5
11.3 Forming a Radius
1. Adjust the pinch roll as needed.
2. Turn on the slip roller and insert the
workpiece from the front. Make sure the
stationary roll is rotating counter-clockwise.
3. When the material reaches the point where
the radius is to begin (Figure 6a), stop the
machine and raise the idler roll an equal
amount on each end to achieve the desired
bend.
Figure 8
4. Re-start the rolls and continue until the bend
is completed (Figure 6b). Support the
workpiece as it exits the machine.
5. If a smaller radius is needed, adjust the roll
distance and re-feed the workpiece.
Figure 6
11.4 Forming a Tube
A tube can often be made with a single pass
through the machine, as follows:
1. Adjust the pinch roller as needed to
accommodate workpiece thickness.
2. Feed the workpiece into the machine. As it
nears the end (Figure 7a), stop the machine
and reverse direction (Figure 7b).
11.5 Bending Wire
There are three wire grooves at the end of the
pinch roll and idler roll, to accommodate a 5/16”,
3/8” and 1/2” wire. See Figure 9.
Use the smallest groove into which the wire will
comfortably fit. Bend the wire using the same
principles as described for forming a radius. To
make a complete loop of wire, use the
instructions for forming a tube.
Figure 9
12.0 Maintenance
Figure 7
3. To remove the tube from the stationary roll,
pull the sleeve outward until it clears the end
bracket; then pivot the roll outward, as
shown in Figure 8.
4. After the tube is removed, reposition the
stationary roll, making sure the sleeve is
pushed back in completely, as shown in
Figure 8.
1. Keep the rolls clean and rust-free, and
periodically apply a light film of oil.
2. Place a few drops of 30W oil into the holes
at each end of the rolls (see Figure 9). Then
operate the machine for a few seconds to
distribute the oil.
3. Apply a light coat of oil to the exposed end
of the stationary roll beneath the sleeve
(shown in Figure 8).
4. Keep the gears lubricated with a good
quality, non-hardening grease. (Remove end
cover to access gears and chain.) Operate
the machine to disperse the grease.
5. Apply a light coat of grease to the pinch roll
and idler roll adjustment screws (see Figure
1).
