  • Page 66 CHAPTER 6: GENERAL DESCRIPTION 5.4. 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 67 CHAPTER 6: GENERAL DESCRIPTION 5.5. Loading of tubes Standard pushers may be used for loading of tubes, provided that the inner diameter of the tubes is less than the diameters of the pushers. If not, there are two courses of action: 1.

    CHAPTER 7: OPERATION SETTINGS Please read the safety instructions provided at the beginning of this manual before handling the following devices. 4.1. 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.
  • Page 84 CHAPTER 7: OPERATION 4.2. Access to the functions By pressing the MENU key, it is possible to access the setting functions. To edit these parameters, the bar feeder must be in STOP mode. To validate a new parameter or a new value, keep [ENTER] pressed until the icon disappears. Depending on your lathe or your production needs, some of the parameters may not be visible.
  • Page 85 CHAPTER 7: OPERATION 4.2.1. Part adjustment 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 86 CHAPTER 7: OPERATION 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 87 CHAPTER 7: OPERATION 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 91 CHAPTER 7: OPERATION 4.2.3. Positions 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 92 CHAPTER 7: OPERATION 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.
