1. STARTING THE BAR FEED SYSTEM
Please read the safety measures explained at the beginning of the Instruction
manual before handling the following equipment.
1.1 Description
All handling, optional accessories and settings required by the bar feed system to carry out
a specific job are part of the set-up.
A few simple operations are necessary to prepare the device to handle another range of
diameters.
The set-up procedures have been divided into 4 categories:
Settings related to installation :
CEnd of bar position
CTop-cut position
Settings related to bar stock and machined parts :
CExample 1: Set-up for round bars
CExample 2: Set-up for hexagonal bars
CExample 3: Set-up for square bars
CExample 4: Set-up for "others" bars
Mechanical settings and optional accessories :
CReplacement of the feeding pusher
CSlope of the magazine table
CSettings of the loading fingers
CSettings of the loading table
Lathe set-up :
CSpindle reduction tubes
COptional accessories for profiled bars
Theprocedurestobe followed are explainedinthis chapter and willbepresentedasconcrete
examples, whenever possible.

2. SETTINGS RELATED TO INSTALLATION
2.1 End of bar
The end of bar position determines the moment when the bar feed enters the loading cycle.
Usually, the end of bar position is adjusted
as closely as possible behind the clamping
systemofthelathe(approximately5mmor
a 1/4" behind the chuck jaws or collet
pads).
This will provide minimum bar stock
remnant.
Regardless of the length of the bars, or
parts, the end of bar position is always the
same.
In very special cases, a different end of bar
setting needs to be selected.
The length of the remnant may vary :
CThe minimum remnant length (Min)
is obtained when the feeding pusher
is just behind the clamping device
while the last part is being
machined.
CThe maximum remnant length
(Max) is obtained when there is not
enough material for machining an
additional part (Lp - 1 mm).
Maximum remnant length =
Lp - 1 mm + Min
End of bar setting :
Important : Before handling the barfeeder, stop the lathe at the end of part cycle.

2.2 Top-cut position
During the loading cycle, the bar is
automatically loaded and positioned into
the spindle, outside the clamping device of
the lathe (chuck or actuator).
This positioning corresponds to a value (Z)
programmed by the operator, which is
equal to the distance between the
measuring cell and the position of the
material in the lathe clamping device.
With this system, the setting is the same for
any bar length.

4. MECHANICAL SETTINGS AND OPTIONAL ACCESSORIES
4.1 Feeding pusher
Three feeding pushers are necessary to cover the entire range of the Quick Load Servo II
bar feed system. Each pusher has a defined range of operation :
Pusher diameter Ordering Nr Diameter Range
**6,35 mm (1/4") *021.011.022 / 6 6 mm - 15 mm (1/4" - 1/2")
12 mm (1/2") *021.011.062 16 mm - 32 mm (>2/3" - 1 1/4")
25 mm (1") *021.011.022 / 25 33 mm - 120 mm (>1 1/4" - 4,7")
* This ordering number corresponds to the complete pusher, with all of the elements
indicated below. When a feeding pusher is ordered for the first time, use this
number.
** 2 extra roller supports, intended to bolster the support of bars of small diameter, are
furnished with the 6.35 mm diameter pushers. Their placement on the loading table
will be determined by the length of the bars to be loaded.
Replacement :
Bring the loading channel into working
mode position (down position), then place
the bar feed system into the STOP mode
(remote station).
1. Loosen the fastening screws (A)
sufficiently to free the groove (C)
that holds the pusher (B) in the
connecting piece (D).
2. Slide the pusher forward by making
into the guide bushing (E).
3. When the rear of the pusher is
sufficiently loosened to be able to
remove it, pull the guide bushing
(E) toward the back to dislodge it.
4. The pusher is now free and can be
removed.
• Place the new pusher into the
opening, and insert the guide
bushing.
• Introduce the rear of the pusher
into the connection piece and push
to a stop.
• Tighten the fastening screws so that they lodge into the groove of the pusher.
• Check to see that the mechanical stop sleeve is properly positioned (see next
section)

START UP MANUAL 17
QUICK LOAD SERVO III
4.1.1 Mechanical stop
The feeding pusher of the Quick Load Servo bar feed system has a set length, which was
determined so that it can function with all types of lathes.
To make sure that they never collide with the clamping device (end of bar improperly
adjusted, or in manual mode, for example), the feeding pusher of the Quick Load Servo
comes with a mechanical safety stop.
When the mechanical stop (stop sleeve) comes into contact with the guide bushing, the
feeding pusher is immediately stopped.
Procedure :
• Bring the loading channel into
work position (down position.
• Open the main access cover.
• Undo the set screws (A) of the stop
sleeve.
• Close the main access cover.
• Move the feeding pusher forward
to the end of the bar position (see
Chapter 7, Handling).
• Open the main access cover.
• Slide the mechanical stop against
the guide bushing (B), and then
move it back 2 mm (.08").
• Tighten the set screws.
• Close the main access cover.
This setting must be done on all feeding pushers when the bar feed system is
being installed, and should be modified ( not necessarily) only when the
clamping device is replaced (collet or chuck). In this case, the end of the bar
position should also be adjusted.

QUICK LOAD SERVO III
4.1.2 Tubing
With regard to loading the tubing, standard feeding pushers may be used as long as the
inside diameter of the tubes is smaller than the outside diameter of the pushers.
If this is not the case, there are two ways to proceed :
5. The first one consists in making
caps (A) and installing them
behind the tubes (B).
For the caps to stay in place while
the bar is rotating, they should be
fitted with an O-Ring.
2. The second one consists in
replacing the head of the pusher
(C) with a special nose (D), 130
mm in diameter (available for
pusher Ø25 mm only).
Des. Ord. Nr Description
D 021.11.104.130 130mm disk
To feed properly inside the spindle
(F), the outside diameter of the
disk (D) should be turned to a
diameter 4 mm (.015") smaller
than that the inside diameter of the
spindle (F) or of the spindle liner.
The head must be adjusted before
it is mounted onto the pusher.
Procedure :
CSwitch the bar feed system in
STOP mode (remote station).
• Undo the set screw (E) holding the
head (C) onto the pusher.
• Remove standard head.
• Install special disk (D), by pushing
it to a stop in the pusher.
• Secure disk with the set screw.

cylinders,
controlling
the vertical
movement of
the table,
release the
pressure to

setting. After
the setting is
complete, they

4.2 Calibration of the loading table
To obtain an optimal loading, the bar must be perfectly centered on the spindle,
regardless of its diameter or profile. Whenever the diameter or the profile is changed, the
position of the loading table is automatically adjusted according to the parameters entered
by the operator.
If, for any reason whatsoever, the position of the loading table would be incorrect (either
too low or too high), it can be corrected.
Procedure :
Conditions: Bars are on the magazine
The loading table is in the low position
1. Select manual mode by pressing the [F2]
key.
2. Bring the loading table in upper position
[F2].
The bar now faces the spindle of the
lathe.
3. The remote command offers icon [F4]
Forward. To obtain the icon [F3] Adjust
the height of the loading table, press the
[1] key.
4. Press the [F3] key.
5. Four icons are displayed :
[F1] raise the table
[F2] ESC (exit without saving)
[F3] ENTER (save)
[F4] lower the table
CEach time the [F1] or [F4] key is pressed,
the vertical position of the table is
modified by 0.25 mm. For substantial
adjustments, keep pressing the key to
keep the table moving in a continuous
motion
CWhen the desired position is reached,
press the [F3] ENTER key to validate the
choice and recalibrate the device at this new position. Since the calibration must be
changed, the command automatically accesses "Parameters related to set-up,
diameter, length, etc." (See Chapter 7 / point 5.2).
The command asks the operator to confirm the setting of the diameter. Using the
keypad, enter the diameter of the bar used to center the table. Press the [F3]
ENTER key twice to validate.
4.2.1 Profiled bars
The loading table of the Quick Load Servo II has been designed, in standard version, to
load various bar profiles. To load square bars, see the Instruction manual, Appendices /
Options for Quick Load Servo II.
