The device is delivered in two cases. One containing the hydraulic unit, the feet and the accessories, the other containing the tube.

  • Page 17: Мounting

    2-11 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.
  • Page 18 2-12 CHAPTER 2: DESCRIPTION Positionning the feet  Open tube case 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.
  • Page 19 (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.
  • Page 20 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...
  • Page 21 CHAPTER 2: DESCRIPTION 2-15 Anchoring to the ground After centring, the feet should be fixed to the ground by means of 8 plugs. The anchorage is effected by passing bolts through the holes in the base plate. The ground must be hard to guarantee the suppression of vibrations. If the machine is installed on unstable ground, it is recommended that the feet be secured to concrete blocks.

    2-16 CHAPTER 2: DESCRIPTION 2.2.3. Security analysis for the correct incorporation Before considering assembling the machine, it is necessary to consider the following points:  Consider security strategies that reduce risks to an acceptable level;  Define the tasks required for applications to predict and assess the need of access and / or for the approach;...

  • Page 23: Hydraulic Connections

    CHAPTER 2: DESCRIPTION 2-17 Once the bar feed system has been aligned and anchored to the ground, the bar feeder must be connected to the interface of the lathe. At this stage, the hydraulic tank may be filled. 2.2.4. Hydraulic connections Procedure : ...
  • Page 24 2-18 CHAPTER 2: DESCRIPTION Operating pressure The operating pressure must be set according to the diameter of the guide tube. Altering the pressure (17) and changing of diameter of the working tube will cause the thrust force to vary. The operating pressure can be adjusted between 0.8 and 6 bar according to the diameters of the bar to be worked.

  • Page 25: Electric Connections

    CHAPTER 2: DESCRIPTION 2-19 2.2.5. Electric connections Connections End-of-bar cable: The end-of-bar cable will be found rolled up under the electric control box. It is protected by a plastic sheath and has a female connector on its end. Unwind the cable and plug it in. Once the plug has been inserted, it is necessary to fix it by screwing its cap to the male connector.
  • Page 26 Transformer T1 Hydraulic pump motor The LNS bar feed systems are equipped with their own thermal protection systems (breakers, thermal relays and fuses, etc.). The power supply for the bar feed system should be connected to the output of a breaker mounted in the electrical control box of the lathe (10 A max.).

  • Page 27: Maintenance

    2.3.3. Spare parts Without the written consent of LNS SA, no addition or modification of the machine or spare parts can be undertaken. LNS SA assumes no responsibility when using spare parts which were not provided by LNS SA.

  • Page 28: Safety Instructions

    Do not attempt to recharge the batteries of the PLC.  For the use and maintenance of the bar feeder, use only parts provided by or recommended by LNS.  If it is necessary to move the bar feeder once it has been originally installed, do not reinstall it before first contacting LNS or its local representative.

  • Page 29: Safety Devices

    By pressing the emergency stop button located on the remote control, the functions of the bar feed system and the lathe are immediately stopped. The LNS company, or its local representative, may not be held responsible for possible accidents or property damage, whether caused directly or not, by any means whatsoever, if certain safety devices have not been included.

    CHAPTER 3: INSTRUCTIONS 3.1. START UP PRODUTION 3.1.1. Change of diameter Thoroughly empty the working tube by repeatedly placing the A1 selector in position R. Remove the female hydraulic connector supplying the working tube. The end-of-bar cable plug must not be removed. Unscrew the wing-screws on the collector so that it is completely free.

  • Page 33: Pusher

    CHAPTER 3: INSTRUCTIONS Screw down the locking bar (69/D). By means of the lever (67/A), turn the jack opening system anti-clockwise (67/C) and the tube will descend. Once the tube is resting on the centring lugs, return the jack device (67/C) to its working position by turning it clockwise until it butts up against the end-stop.
  • Page 34 CHAPTER 3: INSTRUCTIONS Define pusher lenght  Insert a pusher into the spindle and push it until it is 10mm short of the lathe collet.  Make a mark at 190mm, measuring from the lathe spindle (T).  Using a punch (51/C), extract (51/1) the pin (51/G).
  • Page 35 CHAPTER 3: INSTRUCTIONS Internal valve of piston The internal valve of the piston serves to calibrate the quantity of oil that passes from the compression chamber (behind the piston) to the guide tube in which the bar turns. This valve is set in the factory but if, for any reason, the setting has to be adjusted, please proceed as follows: (this setting can be checked only when the bar-feeder is operational).
  • Page 36 CHAPTER 3: INSTRUCTIONS Rotating pushers (option) When extremely small diameter bars have to be guided, it is recommended that the front of the pusher (A) be fitted with a collet (B). The collet has then to be fitted to a rotating ferrule (C) so that the bar does not twist as it draws the pusher.

    CHAPTER 3: INSTRUCTIONS 3.1.3. Loading When the lathe stops and indicates that the bar is finished (end of bar), please proceed as follows: Place the A1 selector in position R  When the pump stops, check that the pusher has been drawn back and that it is no longer between the bar-feeder and the lathe, otherwise move it back by hand (it can happen that some large-diameter...

    CHAPTER 3: INSTRUCTIONS 3.2. Operations Please read the safety instructions provided at the beginning of this manual before handling the following devices. In case of alarm, switch the selector to R (reset function). O Position : The SUPER HYDROBAR HS is OFF. The lathe can be used without the bar-feeder device. Reloading must be done in position 0.

  • Page 39: End Of Bar Position

    CHAPTER 3: INSTRUCTIONS 3.2.1. End of bar position The end-of-bar signal is given when the piston (B) enters into contact with the stop ring (C). This moves up against the pusher disk (D) and releases the microswitch (F). In normal mode, the microswitch is held down by the spring (G).
