    Safety Introduction Before you work with your Bar Feeder, read this manual and the warning labels on the machine. Make sure that everyone who uses this equipment understands the hazards found in and around automatic equipment. Only trained operators should use this machine.
  • Page 18 Do not use the Bar Feeder beyond the recommended speed or material capacity limits. • Do not use the Bar Feeder without a correctly sized spindle liner installed in the lathe spindle. • In the event of vibration or unusual noise, immediately stop the lathe spindle. Do not operate the machine again until you find and correct the condition that causes the vibration or noise.

  • Page 19: Setup Safety

    Rolling bar stock can also pinch fingers. Operational Safety WARNING: The area between the Bar Feeder and the lathe is hazardous. Always press [EMERGENCY STOP] before you put anything between the Bar Feeder and the lathe. Before you run a program, always close the setup lid.

  • Page 24: Bar Feeder Positions

    Lockout / Lathe Setup Position: Press the release pedal [1] at the base, and then push the Bar Feeder back. This mode disables all Bar Feeder motion. With the Bar Feeder in this position, you have easy access to change spindle liners, clean the coolant collector, or do...

  • Page 25: Lathe Setup - Workholding

    3.1.2 Lathe Setup - Workholding A drawback collet is required for bar feed applications. The Bar Feeder holds the push rod in place while the lathe drawtube clamps. If the collet does not pull the bar stock against the push rod when the drawtube clamps, length variation can occur and accuracy cannot be guaranteed.

  • Page 26: Lathe Setup - Haas Spindle Liners

    Use a closer-fitting liner if possible. Put the Bar Feeder in the Lathe Setup position to install spindle liners. Haas manufactures (2) types of spindle liners; extruded spindle liners, which fit most Haas lathes, and a bar-guide-and-spacer spindle liner system for 4"-bar-capacity lathes.

  • Page 27: Bar Setup - Load Bars

    Operation Lathe Setup - Other Spindle Liners Haas extruded spindle liners are designed to fit a wide range of bar stock sizes, and their one-piece finned design helps keep the bar stock centered in the spindle. If you use the bar-guide-and-spacer system or another spindle liner, remember these points: •...
  • Page 28 The lead end of the bar should have a 30-degree chamfer. • Use M19 commands to set the spindle orientation to align the collet flats with the bar flats. in the bar feeder tray. Note that the spindle orientation option is necessary to do this.

  • Page 29: Bar Setup - Transfer Tray Adjustment

    Bar Setup - Push Rod Installation / Removal The Bar Feeder comes with push rods that are 3/4" and 3/8" in diameter. Use the 3/8" push rod for all round stock material that is smaller than 0.8" (20 mm) in diameter. Use the 3/4"...
  • Page 30 Bar Feeder Setup F3.4: Bushing Retainer [1] At the other end of the push rod, pull the retention blade off of the holder block. F3.5: Retention Blade [1] Remove the push rod. Follow this procedure in reverse to install the other push rod.

  • Page 31: Bar Feed Variable Setup

    #3101 (Initial Push Length): The distance the Bar Feeder pushes the material past the reference point (refer to page 17). The examples given in this manual use a reference point at the collet face. This is the distance that the Bar Feeder pushes each new bar for the first time.
  • Page 32 Bar Feeder Setup Press [PAGE UP] or [PAGE DOWN] to find the BAR FEEDER page. Highlight the variable that you want to edit. Type the value and press [ENTER]. Example: #3100=2.150 (2.0" long part + 0.125" cutoff tool width + 0.025" facing allowance) #3101=2.5 (2.5"...

  • Page 33: Reference Position Setup

    Operation 3.1.8 Reference Position Setup The reference position is the zero point that the Haas Bar Feeder uses for all push operations. You usually establish the reference point at the face of the collet or the chuck jaws. NOTE: You must reset the reference position each time you change the workholding or move the Bar Feeder.

  • Page 34: Bar Setup - Charging Tray Angle Adjustment

    Bar Length Reset Procedure If a bar feed does not complete successfully because of an EMERGENCY STOP or an alarm, the Bar Feeder can lose the current bar length and you need to reset it. Enter MDI mode. Press [V], and then [HANDLE JOG].

  • Page 37: Chapter 4 G-Code Reference

    The values stored in Current Commands are not modified. When you command G105, the Bar Feeder does one of these operations, based on the length of the current bar and the value of MINIMUM CLAMPING LENGTH (#3102 or K)
  • Page 38 #3100 or J, then clamps the workholding. The program continues. If the Bar Feeder cannot complete a bar feed operation because of an alarm or [EMERGENCY STOP], the system stops and displays the message Check Position. If you are confident that the bar position is correct, press [CYCLE START] to continue.

  • Page 39: G105 Q Modes

    G-Code Reference G105 Q Modes Q modes are special Bar Feeder commands that you use with a G105 command in MDI mode. They are generally for setup and troubleshooting purposes. This section describes the available Q modes. To use a Q mode, type G105 QX ; in MDI mode, where X is the Q mode number you want to command, and then press [CYCLE START].
  • Page 40 Make sure that the bar is within the space of the charging tray before you execute this command. G105 Q9 - Load Bar: This command causes the Bar Feeder to load a bar from the charging tray and put it in the transfer tray.

  • Page 43: Chapter 5 Programming

    Programming Chapter 5: Programming Program Examples This section has (3) program examples. • Example 1 calls a subprogram in the G105 command to cut off the part. This programming style is most appropriate for solid stock where the cutoff program must cut to the centerline.

  • Page 44: Example 1 - Cutoff Subprogram

    (#3100). • When the subprogram call repeats on a bar, the cutoff subprogram cuts off finished parts and leaves a clean bar end, and then the Bar Feeder pushes out the part length plus allowances (#3100). NOTE: When you write a bar feed program with a cutoff routine and then a bar...

  • Page 47: Example 3 - Double Push

    This example demonstrates a double push on the workpiece. The program contains (2) G105 commands. The first G105 uses the variables values set on the Bar Feeder current commands page. The second G105 uses J and K values to override the variable values.

  • Page 49: Counter

    Programming Counter The Bar Feeder can count either the numbers of bars used, the number of parts made, or the length of material run. A non-zero value set in Max # Parts (#3103), Max # Bars (#3104), or Max Length to Run (#3105) determines the active counting modes. The first non-zero value stops the cycle if more than one is present.

    Loading Short Bars Loading Short Bars F5.2: Short Bars Must Use At Least (2) Pick Arms To machine short bars: When you load short bars on the charging tray, make sure that at least (2) of the pick arms pick the bar up, or the bar may not load properly. NOTE: The actual minimum bar length depends on your setup.
