CAUTION: Lifting and carrying operations should be carried out by
skilled workers, such as a truck operator. Make sure the machine is well balanced.
Choose a location that will keep the machine free from vibration and dust from other
machinery. Keep in mind that having a large clearance area around the machine is
important for safe and efficient working conditions.
TRANSPORTING AND LIFTING
Follow these guidelines when lifting:
The lift truck must be able to lift at least 1.5 – 2 times the machines gross weight.
Make sure the machine is balanced. While transporting, avoid rough or jerky motion, and
maintain a safe clearance zone around the transport area.
Use a fork lift with sufficient lifting capacity and forks that are long enough to reach the
complete width of the machine.
Remove the securing bolts that attach the machine to the pallet.
Approaching the machine from the side, lift the machine on the frame taking care that there
are no cables or pipes in the area of the forks.
Move the machine to the required position and lower gently to the floor.

GENERAL DESIGN DESCRIPTION
You have made a practical choice in purchasing the RDB-500 Hydraulic Bending Machine. It
has been carefully built of high quality materials and designed to give many years of efficient
service. The simplicity of design and minimum effort required to operate the machine contributes
towards meeting schedules and producing greater profits.
The RDB-500 is an electric powered hydraulically operated “Rotary Draw” bending machine. To
bend material, a bending die and counter die are required. The material is hooked by the
bending dies’ hook arm and is powerfully rotated in the clockwise direction. As the bending die
rotates, the counter die arm also rotates about the same axis, forcing the material to conform to
the radius and shape of the bending die.
The RDB-500 Bending Machine you have purchased is built of solid steel ensuring maximum
rigidity. Tongue and groove design with grade 8 bolts throughout provides very high rigidity and
stability.
Throughout this manual are listed various safety-related descriptions for attention. These
matters for attention contain the essential information to the operators while operating, and
maintaining. Failure to follow these instructions may result in great damage to the machine or
injury to the operator.

CAUTION: HAVE ELECTRICAL UTILITIES CONNECTED TO MACHINE BY
A CERTIFIED ELECTRICIAN!
Check if the available power supply is the same as listed on the machine nameplate.
WARNING: Make sure the grounding wire (green) is properly connected
to avoid electric shock. DO NOT switch the position of the green grounding wire if
any electrical plug wires are switched during hookup.
WARNING: Baileigh Industrial is not responsible for any damage caused
by wiring up to an alternative 3-phase power source other than direct 3-phase. If you
are using an alternate power source, consult a certified electrician or contact
Baileigh Industrial prior to energizing the machine.
ELECTRICAL
Motor Specifications
Your tool is wired for 220 volt, 60Hz alternating current. Before connecting the tool to the power
source, make sure the machine is cut off from power source.
Considerations
Observe local electrical codes when connecting the machine.
The circuit should be protected with a time delay fuse or circuit breaker with a amperage
rating slightly higher than the full load current of machine.
A separate electrical circuit should be used for your tools. Before connecting the motor to the
power line, make sure the switch is in the “OFF” position and be sure that the electric current
is of the same characteristics as indicated on the tool.
All line connections should make good contact. Running on low voltage will damage the
motor.
In the event of a malfunction or breakdown, grounding provides a path of least resistance for
electric current to reduce the risk of electric shock. This tool is equipped with an electric cord
having an equipment-grounding conductor and a grounding plug. The plug must be plugged
into a matching outlet that is properly installed and grounded in accordance with all local
codes and ordinances.

No WIRE GAUGE
WARNING: In all cases, make certain the receptacle in question is
properly grounded. If you are not sure, have a qualified electrician check the
receptacle.
Improper connection of the equipment-grounding conductor can result in risk of electric
shock. The conductor with insulation having an outer surface that is green with or without
yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric
cord or plug is necessary, do not connect the equipment-grounding conductor to a live
terminal.
Check with a qualified electrician or service personnel if the grounding instructions are not
completely understood, or if in doubt as to whether the tool is properly grounded.
Repair or replace damaged or worn cord immediately.
Extension Cord Safety
Extension cord should be in good condition and meet the minimum wire gauge requirements
listed below:
An undersized cord decreases line voltage, causing loss of power and overheating. All cords
should use a ground wire and plug pin. Replace any damaged cords immediately.
17
17
CAUTION: Always wear proper eye protection with side shields, safety
footwear, and leather gloves to protect from burrs and sharp edges.
CAUTION: Keep hands and fingers clear of the dies and swing arms.
Stand to the front of the machine to avoid getting hit with the material during the
bending process. When handling large heavy materials make sure they are properly
supported.
OPERATION
Dry Running Machine
Before actually bending, several “dry runs” should be performed. This will remove any trapped
air from the cylinders and hoses. Also, this will familiarize you with the controls and functions of
the machine. To do this, set a bend angle and then activate the hydraulics to extend and retract
the cylinders to simulate a bend.
Setting Bend Angle
1. Reverse machine until both cylinders are fully retracted.
2. Set the digital controller to “0” by pressing the “F1/RST (reset)
button. The lower green number is preset position and the top
red number is the machine position.
3. In order for the machine to function the digital control needs to
have a stop point programmed for more than 5 degrees.
4. Press the “Right/Down” arrow key to activate the lower preset
degree field. Pressing the “Right/Down” arrow key will highlight
each digit field. The digit field will slowly blink when highlighted.
Machine will only bend to 200 degrees. The cylinders will
deadhead when the reach full extension.
5. When the digit is highlighted, press the “UP” arrow key to change
to the desired digit in that field.
6. When the desired bend degree is entered, press the “Circle”
button to save. The machine will now stop at this preset degree.
18
18
7. The digital control and preset should only be used in whole
degrees. For example 90, 91, 92 not 90.1 or 90.5. If any number
is entered after the decimal the control will add 1 to the final
degree. So it’s best to leave it at 0.
8. If you want to compensate for spring back the “0” position can
be set anywhere.
a. For example: Take a piece of material and insert it into
the die and close the counter die.
b. Activate the FWD pedal until the material just starts to
bend.
c. Set your “0” point here and that should compensate for
most of your spring back.
d. Now the preset value can be entered exactly to the
desired degree + / ‐.
9. Another way is to “Add on” spring back values to the preset.
a. To do this set your “0” position with the cylinders fully
retracted.
b. Insert material and bend a part to exactly 90° using a
framing square.
c. When still at the final position. Document the actual machine position.
d. For example: If the control reads 105° take 105‐90 = 15° (90 deg being your desired
bend angle). This will be the value you will add to your nominal degree setting when
entering preset values.
10. There is no right or wrong way to use this control. It is purely the user’s preference.
Home position with 90° Preset Stop Point. Stop position with 90° Preset Stop Point.

DIE SELECTION AND INSTALLATION
Before any bending can take place, the
proper die set must be chosen to match the
material being bent. (EX) 1-1/2” diameter
tubing requires a die set marked 1-1/2”
tube.
A Hook Arm
B Bend Die
C Hold down Bolts
D Plastic Slide
E Counter Die Mount
F Bronze Counter Die Insert
G “0” Mark
Note: Pipe and Tube are not
the same, (see table 1) for nominal pipe
sizes. All BAILEIGH INDUSTRIAL dies are
color coded to avoid confusion between
pipe and tube (see table 2).
IMPORTANT: Damaged or worn
tooling should be replaced before
attempting to bend material. This will
ensure that bends are correct and provide a longer life to machine components.
When handling large heavy dies and/or material, make sure it is properly lifted and supported.
1. To install the die, slip the die over the centering pin until the three unequally spaced drive
pins engage the receiving holes formed in the die.
Note: The die will only fit one way.
2. When the drive pins line up the die will drop all the way down to the spindle.
3. Install and tighten the 1/2-13 socket head bolts provided with the die. Tighten these bolts
enough to hold the die firmly down to the spindle. Approximately 30-40ft-lb. (40-50N•m).
IMPORTANT: FAILURE TO PROPERLY BOLT DOWN DIE WILL RESULT IN
DAMAGE TO MACHINE AND TOOLING.

4. To install the counter die, remove
the hitch pin and insert the counter
die in the opening in the counter die
mount until the 3/4” holes line up.
5. Now insert the hitch pin through all
the holes, reinstall clip on the hitch
pin with the engraved side of the
counter die facing up.
IMPORTANT: Be sure the
long end of the counter die points away from the
hook arm, or to the right of machine.

Bending some thicker or harder material may require the use of a special counterdie with a
1-1/4” pin mounting hole. To install the counterdie with the larger hole the two reducer collars
(N) must be removed.
To do this loosen the (2) set screw (casting type counter die mount) or the 5/16 socket head
screws (welded type counterdie mount) and slip them out of the holes. Counter dies that use
the 1-1/4” pin do not use these reducer collars.
Installing counterdie with 3/4" pin Remove reducer collars to install 1-1/4” counter die pin.
Material Insertion
1. Once the die set is properly installed, the material that matches the die can be inserted (I.E.
1-1/4”tube would go into a die mark D-1250T-R***).
2. Open the counter die assembly and insert the material past the hook arm. The start of bend
mark is engraved with an “O” on the top of the die. Once the material is placed properly, the
counter die slide block assembly can be tightened.
Inserting material to start Lubricating counter die bending
22
22
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.
23

Material Removal
1. After reaching the desired angle, the material needs to be removed.
2. Press the reverse (left) foot pedal. Both the die and the counter die will retract
simultaneously. Run in reverse until all bending pressure is released from the bend.
Activating the quick release lever
3. Activate the quick release counter die lever (A) and completely remove the material.
4. After the material is safely removed, press the reverse (left) foot pedal keeping hands clear
until both cylinders fully retract.
5. The machine is now at the “home” position and can be reloaded for the next bend.
6. Repeat previous steps.

Material Insertion Limitations
Left Right
The left figure shows the recommended minimum / correct amount of material remaining to
be fully supported in plastic slide.
The right figure shows the maximum amount the material can be pulled through the
counterdie. Pulling the material further than shown into the counter die, it will destroy the
plastic slide.
Extreme care must be taken when bending
material with an existing bend. There must
be enough straight material to complete the
bend. If there is not enough material the bent
part of the material will crash into the counter
die and damage the machine and tooling. In
the left figure, there is not enough material to
complete a 90deg. bend. This bend will
damage the dies.
IMPORTANT: Orienting your material in this fashion will cause damage to your tooling
and machine!! DO NOT pull bent material into the counter die! Make sure you have enough
straight material on the draw side of the material to create your bend.
25
25
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.
Bending More than 180 Degrees
This machine is capable of bending more than 180 degrees. Contact Baileigh Industrial
about your application.
o It will require a password to make the machine go past 200 degrees.
o Requires special tooling to allow removal of bent part. If standard tooling is used, the
material will be locked onto the die.
UNDERSTANDING SPRINGBACK
Springback can be difficult to understand. As material is bent, the materials yield strength resists
being formed. As a final degree is reached, the machine will have enough power to hold the
bend at a set degree, but as the pressure of the machine is released, the material has a
resistance built in, so it “springs back”
Springback will vary with every size, type and wall thickness, so it will never be consistent from
size to size.
The best way to determine a materials springback is to do sample bends to 90 degrees until a
perfect 90 is obtained.
At that point document the actual machine degrees.
Full manual mode is the best place to do these tests.
Use the overbend amount and enter that value into the springback field.
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.
26
26
Material Layout
In order to create accurate parts, you will have to layout the material in flat form. First you will
need to determine how much material is used per degree of bend. Use the multiplier table on
Table #3 to determine the arc lengths for the die in use. Or use the following formula:
0.1047x 90 degrees =9.425” of material used for a 90 degree bend.
Once the arc lengths are determined you can begin layout of the material using Diagram #1 as a
reference.
Diagram #1 shows a simple part bent on the same plane in the same direction.
Diagram #2 shows bending based off of a centerline in two directions.
For symmetrical bends, centerline bending is easiest.
For non-symmetrical bends, continuous one direction bending is best.
Another way to layout material is to draw them in a 2D computer software program like Auto
Cad. There are many free programs on the internet. In a 2D program you will draw the parts
centerline only with corresponding clr’s. Then you will be able to list individual segments of
the bent part. This data can be directly entered into the control.
Another program available is BEND-TECH which is a program specifically designed for tube
bending and will give you all of the required data to make a part. This software is available
from Baileigh Industrial.
Bending with a rotary draw bender requires determining the start of bend point which will line
up with the “0” mark on the die. The portion of the tube toward the hook arm will be locked to
the die, the portion toward the counter die is the draw side and will slide along the counter
die and conform to the dies shape/radius.

BENDING SUGGESTIONS
Aluminum Bending
If bending aluminum, lubrication is very important, if the results are less than desirable with WD40 other lubricants can be used such as:
Johnson Paste Wax (seems to work the best)
High Pressure grease
Highly rich dish soap
The bronze counter die must be polished and have no aluminum deposits or it will continue
to pick up metal.
If using BAILEIGH INDUSTRIAL’s standard counterdie is not producing desired results, roller
counter dies are also available.
BAILEIGH INDUSTRIAL has both steel rollers as well as plastic rollers. Plastic rollers are
used primarily for polished aluminum. Steel rollers would be used for non-polished materials.
Some aluminum will crack as it is being bent, 6061-T6 is very hard and may need to be
annealed or ordered in the “T-0” condition. Aluminum will age harden so if possible try to get
freshly run material.
Heavy Wall DOM tubing
If heavy wall materials are bent to a tight radius, they can tend to slip in the hook arm causing a
poor bend result, below are some suggestions
Use a vise clamp on the outside of the hook arm to “lock” the material in place.
Use a piece of two sided coarse emery cloth in between the hook arm and the material, this
works very well.
In only this application, high pressure grease applied to the DIE GROOVE also helps.
BAILEIGH INDUSTRIAL can make special clamps to hold material in place.

Die Parts
1 Main Bending Die
2 Die Cap
3 Quick Release Handles
4 Hook-Arm
5 Hook-Arm Clamp
6 Plastic Slide
7 Slide Mount
8 Quick Release Studs
Square Tooling Setup
1. Install the bending die (1) on to the spindle. Be careful not to pinch your fingers as you lower
the die on to the spindle. The die will only fit on the spindle one way. Bolt the die to the
spindle using the holes in the die.
2. Install the plastic counter die assembly (6, 7) with the long end pointing away from the hook
arm.
3. Snug up the cap clamps (3). Do not over tighten! Or they will be overly difficult to loosen after
the bend is complete. Note: tighten clamps without material in the die. The clamps are lift
and turn, so you can position them anywhere. This allows the handles to clear the counterdie mount during bending.
4. Insert the material in to the hook arm (4) and pull in to the die. It may be a tight fit. Continue
to pull until the material is fully seated in the die’s groove.
5. Lube the counter die and the material that will slide along the counter die. Bring the plastic
counter die assembly up to the material, leaving about 1/8” to 1/4" gap. (Note: on some
thinner material it helps to keep the counter die approx. 1” away from the material)
IMPORTANT: Do not lube the bending die surfaces. This will increase the possibility for
slippage. Make sure all the die cap clamp handles (3) are inside the die diameter. They could
catch the counter die mounting assembly and break off.
31
31
6. If the material slips during the bending operation, install the hook arm clamp (5). Do not use
it unless you have to.
7. Activate the bender and bend to the desired angle.
8. To remove the material, open the counter die and return bender to the “home position”.
Using a soft mallet, gently tap the cap clamps open and the material will spring out of the die
(1). Remove the material and re-snug the cap clamps.
9. Install the next piece of material to be bent and repeat these steps.
Large Size Square
When bending larger than 1.5” (38.1mm) thinner wall square tubing, the counter die position
seems to work better between 1/2" and 1” (12.7-25.4mm) farther away from the die. This seems
do reduce side wall distortion and inner wrinkling. Although this suggestion is to help on large
size, the same steps can be used for any square, if trying to achieve better results. If the square
material slips in the hook arm, use the supplied clamp and bolts to hold in place.
BAILEIGH INDUSTRIAL offer crush bend dies to form a concave crease on the inside of square
bends to reduce the possibility of wrinkling.

WARNING: Make sure the electrical disconnect is OFF before working on
the machine.
Maintenance should be performed on a regular basis by qualified personnel.
Always follow proper safety precautions when working on or around any machinery.
LUBRICATION AND MAINTENANCE
Check daily for any unsafe conditions and fix immediately.
Check that all nuts and bolts are properly tightened.
On a weekly basis clean the machine and the area around it.
Lubricate threaded components and sliding devices.
Apply rust inhibitive lubricant to all non-painted surfaces.
Note: Proper maintenance can increase the life expectancy of your machine.
The fluid level in the power unit’s reservoir should be checked monthly. If the level is below
1/2 full, fill to the top with AW-46 hydraulic fluid. Hydraulic fluid and the filter should be
changed when the filter gauge reads “Change Filter”.
Check periodically for leaks. If a leak is detected, consult Baileigh Industrial.
There are four grease zerks on the machine, at the main spindle pivots. Grease these zerks
every month with only two pumps from a standard grease gun.
Check for any loose or worn parts
If hoses or fittings are replaced, they must be rated for 4000psi (275 bars, 282 kg/cm).

Problem
Solution
Cylinders not retracting all the
way or not in sequence
Do the dry run sequence as outlined in section 8 of the
manual under operation
Machine doesn't move forward
or moves forward slowly and
does not build up pressure
Check that the solenoid valve has its wires connected. To
Check it's functionality extend the cylinder all the way, let
the machine deadhead and build up pressure
approximately 2000 (Psi). At that point rotate the autostop
dial the detent position and the pressure should drop to "0"
Psi.
Solenoid switch
Machine doesn't bend at
pressure (2000 Psi)
If trying to bend material and the machine builds up
pressure and stalls this usually means: The material is too
thick, the material has too high of a yield strength, or the
material is over the machines capacity.
Material slips in the hook arm
Too much lube on material and is transferring to the bend
die clean the bend die with degreaser.
The counter die should be lubed only
The material may need to be clamped
Wrong material for the die set
Spindle drive pins are damaged
If the bend dies are not bolted down properly the drive pins
will get damaged. Replace drive pins.
Poor Bend Results
Check proper tooling for material IE Pipe Vs Tube. Green
for pipe, Blue for tube, Red for metric and Gray for square
or rectangle tubing. See Appendix C for pipe sizing chart
Wall thickness is too thin
WARNING: Make sure the electrical disconnect is OFF before working on
the machine.
