1. SETTINGS RELATED TO INSTALLATION
1.1 End of bar
The end of bar position determines the moment when the bar feed enters the loading cycle
Regardless of the length of the bars, or parts, the end of bar position is always the same.
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).
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

Regulation :
In manual, advance the pusher to just behind the chuck jaw, to the desired end-of-rod
position (see previous illustration).
•To the rear of the bar-feeder, undo the fixing screw (A) holding the end-of-rod probe
support (B) (SQ8).
•Slide the support (B) forwards (1) or backwards (2) until the probe indicator light
comes on.
1. The length of the remnant increases
2. The length of the remnant decreases
•Fix in that position.
•Draw back the pusher then advance it again to ensure that it stops in the set position.
Screw-cutters and lathes with mobile headstocks
•Set the end-of-bar 5 mm
behind the chuck jaw, when
the headstock is in the rear-of-
part position.

1.2 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 avalue (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.

1. Press the [STOP] key.
2. Press the [MENU] key.
The display reads :
PARAMETERS RELATED TO
START-UP
3. Press the key corresponding to the [ENTER] icon.
The following text appears on screen :

4. Advance the pusher out of the connector with the stationary control.
5. Unscrew (1) the collet (A) of the rotating ferrule (B), then strip (2) the elements.
Install the new collet.
6. With the stationary control, move pusher back into the connector.
7. To exit adjustment mode, to press the [MENU] or [STOP] key.

tubes, it is
recommended
to plug the
rear end of
the material
so that the oil
from the bar-
feeder and the
cutting fluid
do not mix
To order collets, indicate the article number, followed by the desired internal diameter.

(*) It is possible to replace the barrel and so to increase or decrease the capacity of the bar-
feeder. Other elements such as the connector must also be replaced. Instructions
indicating the replacement procedure is delivered with the material..
2.2 Feed pressure and speed
To adjust the feed pressure and speed, the bar-feeder must be in automatic mode. Block the
pusher at the exit of the barrel then proceed as follows :
•The hydraulic pressure indicated on the manometer (A), can be set to between 0.8 and
5 bar, according to the diameter of the bars and the guidance tubes. Screwing down the
regulator (B), increases the pressure.
•The feed speed can be adjusted to between 50 and 200mm per sec. Close the regulator
(C) slowly until the pressure falls. Reopen until the pressure stabilises. In this position,
the feed speed is at its minimum. To increase it, unscrew the regulator (C).

3. PUTTING THE LATHE INTO OPERATION
3.1 Spindle reduction tubes
Theefficiencyof thebarguiding whileinrotationinthelatheisdeterminedbythe clearance
between the spindle reduction tube and the rotating bar. The greater the clearance is, the
more frequent the vibrations are.
Using reduction tubes helps to decrease this clearance. Guiding is thus improved, but, in
addition, the insertion of the bar into the clamping device of the lathe is made much easier.
The inside diameter of the reduction tubes should be chosen in terms of the diameter of the
bar (diameter of the bar + 1 mm), but should always be larger than that of the diameter of
the feeding pusher.
Spindle reduction tubes are available from LNS, upon request
3.2 Shaped bars (hex and square)
It is possible to install abushing, inside the clamping device, with the same inside profile
(+ 0.2 mm) as the bar.
The rear of this collet and the front of the bars should be flat.
During the loading cycle, a slight rotation of the spindle (about 30 RPM) is desirable.
