1. PUTTING THE BAR FEED SYSTEM INTO OPERATION
Please read the safety instructions provided at the beginning of this manual
before handling the following devices.
1.1 Description
Any handling, adjustments and settings required by the bar feed system so that it can
undertake a specific task are part of putting it into operation.
The device may be prepared for a different range of diameters by means of some very simple
operations.
The process for putting the bar feed system into operation must be modified when :
CThe diameter of the bars changes
CThe profile of the bars changes
CThe length of the part changes
The procedures to be followed are shown in this chapter. When a setting needs to be done
on one of the devices, it is referenced in the chapter dealing with this subject.

2. SETTINGS RELATED TO INSTALLATION
2.1 End of bar position
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 - 1mm + Min

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.
The setting for the Top-cut position may be
adjusted at any time, in one of two ways :
1. By offset correction
2. By teach in
Top cut position setting :
Important : Before handling the barfeeder, stop the lathe at the end of part cycle.

CPress the key attributed to the icon [+/-].
The display reads the current top cut position.
CEnter the correction value with the numerical keys. Then, press the key attributed to

CPress the key attributed to the icon [TEACH IN].
CPress the key attributed to the icon [START].
The movable vise closes and advances the bar stock against the front stopper. The
bar is thus measured. The movable vise continues its travel and positions the bar
inside the spindle of the lathe. The guiding channel closes. The feeding pusher is
now facing the bar. The feeding pusher moves forward and positions the material
inside the collet of the bar feed system.
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
disappears.

STOCK DIAMETER]. Similarly, when the pusher is in the front rest, the motor (M3) adjusts
the gap according to the setting entered into the [ENTER NEW GUIDING CHANNEL
NUMBER] parameter.
