    2. INSTALLATION When this instruction manual was printed, the information given was correct. However, since we are constantly improving the design of our Barfeed’s, it is possible that the illustrations and descriptions may vary from the Barfeed supplied. When supplied for installation within Europe, the Barfeed carries the CE mark of incorporation, and should be declared in conformity with the EC Directives after safe installation with the Lathe.

  • Page 7: Delivery And Inspection Of Barfeed

    3.4 Check that a suitable air supply (70psi 5bar) is available for connection to Barfeed. If the pressure is below 5bar the Barfeed will not respond, 5bar is to be a recognised pressure for the Barfeed to operate safely. Delivery and Inspection of Barfeed 3.10 The Barfeed should be removed from it’s packaging, exported Barfeed’s are supplied in a wooden transit box, in this case remove screws from around base, (usually about 16-off), and lift top section of box up and over the top of the Barfeed.
  • Page 8 Figure 30.3 Multifeed 3.24 Open the cover on the Barfeed and remove the black plastic transit spacers from the cross slide bars, then close the cover. 3.25 Connect air supply via filter bottle located at side of stand Note; Minimum air supply 70psi(5bar). 3.26 Check the transformer settings and the voltage output from the Lathe, if these are specified for correct interface proceed to stage 3.27, otherwise contact the Lathe agent for alterations.

  • Page 9: Alignment Procedure

    Alignment Procedure 3.30 Latch the smallest bore Push Rod bushing into the front support block that is positioned Lathe side of Barfeed. 3.31 Clamp the line-up bung that’s supplied into the collet/chuck. 3.32 Feed a 2mm (5/64”) cord through the orifice of the Pusher block, and then be sure that it’s tied behind the block using the aid of a knot or clamping device.
  • Page 10 OPERATION 3.40 You are able to manually operate the Barfeed’s basic functions through the screen. Loading Cams Cross Slide Insert Pusher Main Pusher This just simply allows the operator to manoeuvre the positions of the working functions for whatever reason. After set-up, the pushrod pushes the material forward as requested by the Lathe until the bar is fed to a Lathe stop.

  • Page 11: The Barfeed Master Spindle Reduction Liner System

    The Barfeed is supplied with the necessary master liner, five sets of bushings and one set of steel spacers to suit the CNC Lathe as standard. Extra sets of bushings can be supplied blank or bored from Hydrafeed Limited, or made ‘in house’ to the specifications in the drawings.
  • Page 12 The clearance between the O.D. of the bar and the remainder of the liner or liner bushings should be approximately 0.5 mm over the bar O.D. and the effective length of the support bushings should not be greater than 25mm, except with very small diameter bar, i.e.

  • Page 17: Height Adjustment Of The Support Channel

    4.4. HEIGHT ADJUSTMENT OF THE SUPPORT CHANNEL Ensure that Cross Slide and support channel are in the ‘out’ position. Place the material to be used on the support channel, and slide material forward by hand towards the lathe spindle. Unclamp the two locking handles indicated in figure Raise or lower the channel to the height at which the material can easily be inserted into the spindle with out much interference.
  • Page 18 Move the stops so that the material is against the stops in the position shown in figure 13. Then adjust the stops so that only one piece of material is lifted into the V-channel. Once this has been established be sure to tighten the stop screws securely. Figure 13 Adjustment stops Cam lever...

  • Page 19: Changing Or Removing The Push Rod

    4.6. CHANGING OR REMOVING THE PUSH ROD The mechanical Pusher latch is designed so that when the push rod is in line with the spindle the Push rod is latched to the main carriage therefore allowing insertion of material to be fed through the collet section. When the Insert Pusher is in line with the spindle the push rod will be detached from the carriage therefore allowing insertion of material to be loaded into the spindle section.

  • Page 20: Pusher Forward Movement Sensor

    5.1 PUSHER FORWARD MOVEMENT SENSOR Figure 20 This sensor detects the forward movement of the Main Pusher. This signal information is used to finish the M-Code signal (that is generated from the Lathe), when the Main Pusher has stopped moving, ie fed to Lathe stop, the Barfeed will then generate an M-Finish signal to the Lathe to cancel the M-Code so machining can continue.

  • Page 21: Location Of Cross Slide Sensors

    5.2 LOCATION OF CROSS SLIDE SENSORS Figure 21 Cross Slide Out Sensor Cross Slide In Sensor (X15 input) (X14 input) Cross Slide Out Sensor: this sensor is only activated when the Insert Pusher is aligned with the spindle centre line. Cross Slide In Sensor: this sensor is only activated when the Main Pusher is aligned with the spindle centre line.
  • Page 22 5.4 LOCATION OF GUARD SWITCH Figure 23 This switch comes in two parts, (switch and actuator) and they are separately mounted, the switch is fixed to the front apron of the Barfeed and the actuator is fixed to the guard hood. When the hood is closed the actuator locates in the switch and this will allow electrical operations in the Barfeed to be carried out.

  • Page 23: Location Of Material Sensor

    5.5 LOCATION OF MATERIAL SENSOR Figure 24 This sensor is capable of detecting the different types of materials that is used, the characteristics of this sensor is that there is a light beam that deflects from a reflector which is mounted opposite the sensor inside the front cover, so when the beam becomes broken a signal is generated to the control system.
