  • Page 92 8-10 CHAPTER 8: OPERATION MATERIAL SHAPE This parameter controls the sequence of the loading process at the point when the material must be passed through the clamping device. When round material is selected, the loading process is simple, because the material will pass through the clamping device regardless of the orientation of the bar stock or spindle.
  • Page 93 CHAPTER 8: OPERATION 8-11 The value entered into this parameter should correspond as follows: Part length (Lt) = Finished part length (Lp) + width of cutoff tool (C) + amount of facing (if applicable) NUMBER OF CLAMPING DEVICE OPENINGS FOR OVERALL PART LENGTH When the machining of a finished part requires several openings of the clamping device (for ex.: a long part, or transfer of the part to the sub- spindle), interface conflicts may occur during the feeding process.
  • Page 94 (with respect to the above mentioned part). For further details on this option, please contact LNS SA or its local representative. Notice: the lathe must be capable of supporting the spare interface signals required for this option.
  • Page 95 CHAPTER 8: OPERATION 8-13 3.2.2. APPLICATION SETUP Menu The APPLICATION SETUP menu contains an enumerated parameter that configures how the bar feed system will conduct the feeding process while in automatic production. Below is a layout which follows the same structure as seen on the actual control. The parameters outlined with the dash-dot lines may or may not be visible in the control, depending upon whether the features have been unmasked in the service section of the menu and also depending upon how certain applications are setup.

Clamping system Collets There are different kinds of collets that are more or less effective: a) Simple cone collet: The bar is held over about 350 degrees, over a length from 0.5 to 7 times the diameter. Efficiency : good to very good b) Bi-conical collet: Clamping over 1 or 2 x 350 degrees, over an...

    For inserting and removing the spindle reductions, move the bar feed system using the retraction device (Chapter 7). Spindle reduction tubes are available from LNS upon request. It is recommended to have spindle information available since these reduction tubes are custom made according to the specific spindle...

    8-30 CHAPTER 8: OPERATION 5. AUTOMATIC CYCLE The bar feed autonomy is depending on the bar stocks placed by the operator on the loading ramp. This task can be performed during the production cycle, unless the end of bar has been reached. Prior to starting the automatic cycle, it is recommended to check following points: On the loading ramp, the material must be loaded against the rear limiter.

    CHAPTER 9: MALFUNCTIONS 1. FACTORS AFFECTING PERFORMANCE 1.1. Installation The installation is a very important phase that, if neglected, could seriously impede the operation of the bar feed system. Distance The distance between the bar feed system and the lathe influences the quality of the guiding immensely.

    CHAPTER 9: MALFUNCTIONS 1.4. Material To obtain a perfect insertion inside the pusher collet, the bars must Solid bars be chamfered concentrically (at the rear) at 30° . It is also recommended to deburr the bar at the front, to avoid possible catching as the bar enters the spindle and/or clamping system.

    CHAPTER 9: MALFUNCTIONS 2. MAINTENANCE Please read the safety instructions provided at the beginning of this manual before handling the following devices. 2.1. Hydraulics It is important to clean the bars (even briefly) before loading them on the feed system magazine. Excessive dirt can form a deposit at the base of the bar feed system, which can in turn slow the oil return and can possibly cause premature pump failure if it enters the hydraulic pump.
