  • Page 26: Pusher Reversing Distance Adjustment

    PROCEDURES PUSHER REVERSING DISTANCE ADJUSTMENT The pusher reverses a specified distance, after the chuck closes, so that it is not making contact with the rotating bar or the spindle. Generally, the smaller the diameter of the pusher the greater the reversing distance. This is due to deflection (or sagging) of the pusher, which is caused when the pusher is far up in the spindle of the lathe and can no longer support its own weight so the tip of the pusher begins to sag.

  • Page 27: Magazine And Loading Finger Adjustment

    PROCEDURES MAGAZINE AND LOADING FINGER ADJUSTMENT The slope of the magazine rack needs to be adjusted when the shape of the material being loaded changes from round to profiled or visa versa. When loading round stock, if the slope of the magazine is too much it is possible for the material to stack up and cause double loading if the weight of the material is great enough (especially when loading smaller diameter stock).

    MECHANICAL EQUIPMENT LOADING TABLE DESCRIPTION When they are on the magazine, the bars (A) press against the loading stops (B). The stops are arranged on an axis (C) which is coupled to the loading table (D). The stops are adjusted automatically by the electric motor M2, at the same time as the loading table is configured.

  • Page 36: Pusher Carrier

    The length of the pushers is fixed and does not depend on the spindle length. As a safety measure, the pushers are equipped with a mechanical stop. For loading of tubes, profiled bars or short bars, optional elements may be installed. Please contact your local LNS agent for more information.

  • Page 37: Loading Pusher

    MECHANICAL EQUIPMENT LOADING PUSHER Contrary to the feeding pusher, the loading pusher (2) does not need to be replaced when the bar diameter changes. Same-length bars may be loaded directly with a loading pusher without using the feeding pusher. To do this, a special extended loading pusher, available as an option, is required.
  • Page 38 MECHANICAL EQUIPMENT MECHANICAL STOP The bar feeder pusher has a fixed length, which was determined to ensure it is suited to all types of lathes. To guarantee that they never collide with the collet (for example: end of bar incorrectly set or in manual mode), the bar feeder pushers are equipped with a mechanical safety stop.
  • Page 39 MECHANICAL EQUIPMENT 2. The second consists of replacing the pusher tip (C) with a special tip (D) with a diameter of 130 mm (available for the ø 25 mm pusher only). To enable it to penetrate the spindle (F), the tip must be turned at a diameter 4 millimeters less than the spindle passage (F).

  • Page 40: Retraction

    MECHANICAL EQUIPMENT RETRACTION When a lathe is equipped with a bar feeder, certain elements (motors, spindle reduction tubes, etc.) become inaccessible, and sometimes it is difficult, or even impossible, to proceed with their maintenance. To facilitate these tasks, the bar feeder is equipped with a retraction system which allows the operator to move it. Designation Description Rails...

  • Page 65: Settings

    SETTINGS 6. SETTINGS This chapter indicates the activating and setting procedures for these functions. DESCRIPTION The bar feeder has several parameters and functions allowing the operator to configure it so that it adapts as closely as possible to the lathe on which it is installed, as well as to the production mode being employed. Thanks to these parameters, when feeding, the material can be positioned in the lathe's clamping unit.

  • Page 66: Access To The Functions

    SETTINGS ACCESS TO THE FUNCTIONS By pressing the MENU key, it is possible to access the setting functions. INFORMATION To modify these parameters, the bar feed must be in STOP mode. To validate some values or parameters, hold the [ENTER] key until the icon disappears.
  • Page 67 SETTINGS PART SETUP Form and diameter of the bar, length of part, face-off variable distance Material shape Round bar: • Outside diameter Hexagonal / square bar: • Size on flat sides • Size on corners During the bar feed cycle, the bar feeder tries several times (during 2 minutes) to insert the bar in the lathe collet or chuck.
  • Page 68 SETTINGS Top-cut position(may not be visible) During feeding, the bar is inserted in the spindle and automatically positioned in the clamping unit of the lathe. 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.
  • Page 69 SETTINGS End of bar position (may be not visible) The end of bar position determines the moment when the bar feeder enters the loading cycle. In principle, the end of bar position is adjusted as closely as possible behind the lathe's clamping unit (approximately 5 mm) to ensure the shortest remnants.
  • Page 70 This parameter must only be used when a physical limiter is in place on the bar magazine to prevent longer bars from being loaded, which could damage the lathe. Please contact your LNS agent for more information on this application.
  • Page 71 SETTINGS Part feed out rate (may not be visible) This parameter is used to adapt the feed rate to the weight of the bar, for example when feeding out aluminum bars. APPLICATION SETUP Part feed out with/without turret Part feed out with turret This parameter determines whether the lathe controls the part feeding.
  • Page 72 The end of bar position does not require any particular setting for this type of work. Contact your LNS agent for more information on this application. Misc. Applications Auto cycle simulation function - Dry Run (may not be visible) This function allows the lathe to be used (in a production cycle) without the bar feeder (piece work, lathe preheating, etc.).
  • Page 73 SETTINGS POSITION End of bar position (may be not visible) The end of bar position determines the moment when the bar feeder enters the loading cycle. In principle, the end of bar position is adjusted as closely as possible behind the lathe's clamping unit (approximately 5 mm) to ensure the shortest remnants.
  • Page 74 SETTINGS Auxiliary end of bar position (may be not visible) Depending on the lathe and its options, the auxiliary end of bar may be used in several ways. For example, for the opening of an additional front rest installed at the rear of the lathe spindle. The procedure is the same as this for the end of bar signal. TORQUES Torque set according to the diameter for part feed out (%) Depending on the bar diameter, the feeder suggests a suitable thrust torque.
