The Haas Bar Feeder is for ST10/15/20/25/30/35 and DS-30 lathes.

It is not for ST-30/35 or DS-30 lathes with a gearbox.

This procedure tells you how to install a bar feeder that was made after June, 2017. If you have CHC machine please follow the procedure below.

Press [POWER OFF] on the lathe.

Set the main circuit breaker to the OFF position.

Lock the main circuit breaker. Use an approved lock with an approved safety tag.

If the lathe is an ST-35, or if the machine was made before 11/1/2015, install the coolant collector extension [1] onto the lathe.

Attach the spindle liner adapter [2] to the spindle. Refer to Lathe - Extruded Spindle Liner - Adaptor Kit - Installation. If the lathe is an ST-35, refer to Lathe - ST-30/30Y Big Bore, ST-35/35Y - Spindle Liner Kit - Installation.

Put the bar feeder adjacent to the lathe.

Make sure the frame ends [1] are parallel to the front [2] of the lathe.

Remove the shipping brackets [3] from the frame of the bar feeder.

Pull the bar feeder [1] forward until it locks into position.

Find the end of the bar feeder [2].

If the lathe is an ST-35, find the end of the coolant-collector extension [3].

If the lathe is an ST-10, ST-15, ST-20, ST-25, ST-30, or DS-30, find the edge of the coolant collector.

Make sure that the space [4] between them is approximately 0.50" (13 mm).

Find the (4) height adjustment screws [1].

Turn the screws [3] until the frame is 2.0" (51 mm) [2] above the floor [4].

Find the access door [2] at the bottom of the control cabinet [1].

Open the access door.

Install the conduit bracket [3] to the bottom of the control cabinet.

Use (2) screws to attach the bracket.

Find the cable conduit [2] under the bar feeder.

Put the cable conduit through the hole [1] in the side of the lathe enclosure.

 Note: Some lathes do not have the hole. If the lathe does not have a hole, make one with a 2.0" (51 mm) hole saw. No hole is necessary for the ST-10.

Put the conduit through the conduit bracket [3].

Push the conduit [5] up through the cable exit [4] in the bottom of the control cabinet.

Open the control cabinet.

 Danger: If the voltage indicator light is on, do not touch the electrical components. The high voltage in the control cabinet can kill you. Wait for the voltage indicator LED to go off fully.

Find the location on the amplifier bank that has the "BAR FEEDER /W AXIS" label [1].

Install the 30-Amp servo amplifier [2], included with the bar feeder, into that location.

Find the (3) bar feeder power wires that come through the conduit.

Connect the power wires to the high voltage terminals:

• red to RED [1]
• white to WHT [2]
• black to BLK [3]

Connect the ground wire [4] to the bracket for the amplifier fan.

Find the high-voltage terminals [5] on the nearest amplifier.

Find the high-voltage terminals [7] on the bar feeder 30-Amp amplifier.

Install the jumpers [6] from the installation kit between these terminals.

Connect the black wire to -H.V. Connect the red wire to +H.V.

Install a ferrite filter P/N 64-1252 bead around the red, white, black cables going to the bar feeder motor.

 

Connect the current command cable, included with the bar feeder, to the connector [1] at the top of the amplifier.

Connect the other end of the cable:

• Connect to channel 10 (P10) [2] on the Maincon PCB.

Find the servo motor encoder cable in the conduit.

Connect the servo encoder cable:

• Connect to channel 10 (P26) [3] on the Maincon PCB.

For Lathes equipped with the 34-348xA, 34-348xC  I/O PCB:

Connect these cables from the conduit to the I/O PCB:

• Cable 200 to P62 [1]
• Cable BF Input to P59[2] Install a ferrite filter P/N 64-1252 bead around the cable at the I/O board.
• Cable 810 to P58 [3] 

For Lathes equipped with the 34-349x

• Cable 200 to P62 [1]
• Cable BF Input to P59[2] Install a ferrite filter P/N 64-1252 bead around the cable at the I/O board.

For Lathes equipped with the 34-349x I/O PCB:

 Note:  Bar Feeders built after January 14, 2019 will have a Tool Changer PCB kit included in the electrical kit.

• Install the TC PCB on the standoffs.
  
• Connect cable P/N 33-0413 from J1 [2] on the TC PCB to P74 [3] on the I/O PCB.
• Connect cable P/N 33-0412 from P55A [4] on the TC PCB to P55 [5] on the I/O PCB.
• Connect cable P/N 33-0349 from P4 on PSUP PCB to the P55 [7] on the TC PCB.
• Connect the bar feeder cable to P58 [6].

Note: If the machine generates multiple Alarm 20014.1 SIO TOOL CHANGER PCB IS NOT PRESENT and 20014.0 SIO TOOL CHANGER PCB PRESENT after the I/O TC PCB is installed. The I/O or TC PCB firmware is outdated. Update I/O Main and TC firmware version to the latest.  Refer to Next Generation Control - I/O PCB Main Firmware - Update.

Look at the transfer table [1] on the bar feeder.

The groove in the transfer table aligns with the spindle adaptor.

Tap the frame ends [2] with a rubber mallet [3] to move the bar feeder.

Press [EMERGENCY STOP].

Turn the adjustment wheel [3] for the transfer table until the table is at the bottom.

Install the 0.75" push rod [2] on the push rod assembly [1].

Refer to the Operator's Manual for instructions to install the push rod.

Remove the left-hand rack for the spindle liners.

Remove the sticker [3] from the socket hole [4] on the bar feeder.

Put the sticker above the socket hole.

Find the (8) cart screws [5].

Each side of the bar feeder has (4) screws.

Loosen the (8) screws.

Put the adjustment tool [2] into the socket.

Release the [EMERGENCY STOP].

Press [RESET] to stop each alarm.

Press [RECOVER] to enter the bar feeder recovery mode:

Press [F2] to load the push rod.

The pusher clears the tray then the push rod assembly moves down.

Press [EMERGENCY STOP].

Use your hand to move the push rod actuator [1] toward the lathe.

Use the adjustment tool [3] to move the bar feeder [2] up or down until the push rod can go into the liner adaptor.

Perform the Haas Bar Feeder - Push Rod Alignment procedure.

Make sure the enclosure [1] is level to the ground.

Tighten the (8) cart screws [2].

Remove the adjustment tool.

Replace the racks for the spindle liners.

Find the (4) height adjustment screws [3].

Look at where the push rod [2] goes into the spindle adapter [1].

Turn the (4) height adjustment screws until the center of the push rod aligns with the center of the adapter.

Look at where the push rod [4] goes out of the spindle [3].

Turn the (4) height adjustment screws until the center of the push rod aligns with the center of the spindle.

 Note: Gravity pulls the end of the push rod down a small distance.

Tap the frame ends with a rubber mallet to move the bar feeder from side-to-side, if necessary.

Return the push rod to its home position.

Step on the release pedal.

Push the bar feeder backward to the end of its travel.

If the bar feeder is correctly leveled, the gas shock holds the bar feeder in the rear location.

If the bar feeder must be aligned, adjust the rear feet until the bar feeder smoothly locks in the forward position and moves fully backward.

Turn the rear feet [1] until they are parallel to the bottom rails, as shown.

The front feet [2] must remain perpendicular to the bottom rails, as shown.

Use a pen [1] to put a mark on the floor at the location of each foot.

 Note: Turn the feet to the sides of the bar feeder to avoid a tripping hazard.

Drill [2] a Ø 0.50" (13 mm) hole in each mark.

Drill the hole to a depth of 3.5" (89 mm).

Put a washer and a nut on the bolt [1].

Put the foot over the hole .  Put the anchor into the hole.

Use a hammer [2] to tap the anchor.

Tap the anchor [3] until it is at the bottom of the hole.

Torque each nut [4] to 55 ft-lb (75 Nm).

Press [RECOVERY] button to enter the bar feeder recovery mode.

Place a precision ground calibration bar with a known length on the charging table.

Press [ORIGIN], type in the length of the calibration bar and press [ENTER].

The pusher clears the tray then loads the calibration bar. It will then measure the length of the bar and apply the calibration.

Remove and properly store the calibration bar for future use. A bar feeder only needs calibration at installation, or if the EOB sensor, home switch, or trolley are disassembled or replaced.

Note: If the message No Material Found is displayed when the bar is pushed towards the spindle passed the EOB sensor during calibration. Update the I/O Main and TC firmware version to the latest. Refer to Next Generation Control - I/O PCB Main Firmware - Update for the latest firmware for the machines I/O  & TC PCB part number.
