Height - 90 mm - 1100 mm - 1100 mm
Unpacking
For practical and safety reasons, the bar feed system must be unpacked in a spacious, well-lit location.
Check to see that the lifting capacity of the hoisting crane, or lift truck, is adequate before
proceeding with the handling of the merchandise. No one should be near the hanging load,
or within the operating range of the overhead hoist/crane, forklift, or any other means used
for lifting and transportation.
1) If the bar feed system is received in a crate, start
by unscrewing the front panel.
2) Remove the top.
3) Remove the side-walls.

Préparation pour le montage
For mounting and installing the bar feed system, it is advisable to contact LNS or
one of its agents. The latter cannot be held responsible for any malfunction
resulting from an incorrect installation in which they did not take part.

It is essential that the lathe be levelled before installation of the bar-feeder. The lathe
must be fitted with a collet or chuck in order to perform the bar rotation tests.
2.2.2. Мounting
Preparing the feet
Please refer to points 2.1.2. for the designation of the components
Open the oblong case by unscrewing the front plate. Inside you will find the hydraulic unit, the front and
back feet, the tube supports and all the small material you will need.
Align the feet approximate on the head stock. Then place
the levelling plates (see point 3.2) under the feet and
centre them on the level-adjusting screws. Level the feet.
Place the rear support (25/A) with the two guide pins on
the swivelling plate (25/B) of the rear foot and insert the
guide pin into it (25/D).
Pass the fixing bolt (25/C) though the dowel and screw it
tightly to the support. As the dowel (25/D) is thicker than
the swivelling plate, the support (25/B) remains free.
Tighten the safety screw (25/E), preventing the bolt (25/C)
from coming unscrewed.
Next place the front support (30/A) bearing the two
centring plates on the front foot (30/B). Also install the
loading arm (it is impossible to do this when the support is
fixed)
Insert the 4 fixing bolts (30/C) into the support plate and fix
the front support. When the bolts are blocked, it should
still be possible to move the loading arm.

2-12 CHAPTER 2: DESCRIPTION
SUPER HYDROBAR HS
Positionning the feet
Open the tube case by
raising its lid.
Remove the tube (see lifting
instructions).
Measure the distance (Y)
between the front of the tube
and the centring lugs. Place
the front foot at a distance
equivalent to Y+150mm from
the spindle exit.
Place the rear foot, leaving a
space (X) being the distance
between the centring ring at
the front and the indexing
ring at the rear of the tube.
To define (X), the measurement has to
be made as follows:
FIG.32a
On the centring ring (32a),
measure to the middle of the
horizontal (PH) and vertical (PV)
centring lugs
On the front foot, this point is
located between the horizontal
(32a/AH) and vertical (32alAV)
support plates.
On the indexing ring, measure to the
middle of the positioning groove (32b/R).
On the rear foot this point corresponds to the centre of the positioning
lugs (32b/G).
When the tube is in place, the front must to be
150mm from the exit to the spindle (Fig.33).

CHAPTER 2: DESCRIPTION 2-13
SUPER HYDROBAR HS
Stripping the tube
On the indexing ring (rear support), there is a
groove which ensures the longitudinal positioning of
the tube when indexing.
Please make sure, when installing, that this groove
has engaged in its guidance system (35/B) and that
it is not damaged.
The lateral (40/C) and vertical (40/B) centring lugs
are screwed into the SUPER HYDROBAR HS
centring ring (front support). These lugs ensure the
centring of each tube.
The individual centring of the tubes was done at the
LNS factory.
The lugs must align with the corresponding cut-outs
on the front support. Therefore, the indexing ring
must not be moved otherwise the centring of the
tubes can no longer be guaranteed.
Carefully place the tube (35/A40/A) in its front and
rear supports. While turning the indexing ring by
means of the tool supplied with the SUPER
HYDROBAR HS, bring the largest diameter tube to
the 6 o'clock position.
Swing the fixing stem into its support while making
sure that the centring lug (35/C) is engaged in its
conical hole. Bring the blocking lever (35/D) to bear
on the cut-out in the stem and tighten it.
Check that the centring lugs (40/B,40/C) are positioned correctly in relation to the cut-outs in the
front support. Make any possible corrections by moving the foot and not by moving the centring
ring. Close down the fixing lever (40/D) and then fix by means of the handle (40/E).
The foot and the centring ring must always be perfectly parallel.

SUPER HYDROBAR HS
Alignment
Before proceeding with the alignment of the bar feed system, ensure that the lathe is
stable and preferably levelled.
During the alignment, ensure that there is no reduction unit in the spindle (spindle
liner).
The alignment of the SUPER HYDROBAR HS is unquestionably the most important point in ensuring
maximum performance and must be conducted with the utmost care.
An alignment error inevitably results in a reduction in rotational speed and can, in the worse of cases,
cause damage to the guide tubes, the pistons and the pushers.
If possible, this installation should be conducted using the LNS alignment checking tool (optical sight). If
the assembler does not have this tool, proceed as follows :
To conduct these checks, the pusher must firstly be removed (see point 3.1.2.) from the
biggest of the guide tubes (reference tube).
1) Insert a nylon thread into the reference tube (which will be aligned on the head stock).
2) Prepare a plug (55/A) with a 2.2 mm hole in its centre which is inserted into the rear of the guide
tube. Pass the nylon thread through this hole and knot it.
3) Bring the tube to the working position
4) Pass the nylon thread through the head stock and fix it with the collet (55/B).
5) Fix the collet in the material collet of the lathe, tension the nylon thread and block it.
6) Use centring disks to check the horizontal and vertical gaps at the exit of the SUPER HYDROBAR
HS (55/C) and entry to the head stock (55/D).
7) Move the front and rear feet until the nylon thread pass precisely through the centre of the guide
tube and the centre of the mouth of the head stock.
8) Tighten the screws (F) or the nuts (G) to raise the tube, loosen them to lower; when the height is
correct, tighten the flanges to secure the whole structure (G). (see points 2.1.2.)
9) Block all the securing screws
