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 "other" 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
The procedures to be followed are explained in this chapter and will be presented as concrete
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 system of the lathe
(approximately 5 mm or 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.
1. Press the key [STOP].
2. Press the key [MENU].
The display reads :

CTo validate the new end of bar position, keep [ENTER] pressed until the icon
disappears.
5. To exit the set mode, press the keys [MENU] or [STOP].
Note: If only the OFFSET function is needed, this can be accomplished by pressing [1] in
sequence 3 above, then pressing the key attributed to the icon [PAGE DOWN] until the
parameter is displayed. The "Teach In" function is not available in this menu.

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.
Top cut position setting :
Important : Before handling the barfeeder, stop the lathe at the end of part
cycle.

The loading channel raises and loads a bar as it passes by. The feeding pusher
inserts the bar into the lathe spindle. The feeding pusher returns to its reference
position. The loading channel goes down. The feeding pusher is now facing the
spindle.
CPress the key [FWD] and advance the bar stock to the desired position (see
previous page).
CTo validate the new top cut position, keep [ENTER] pressed until the icon
