Follow this procedure to turn on a Chucker Lathe for the first time.

Before you do this procedure, make sure that possible crash areas, such as the spindle, and tool changer are clear and that all shipping brackets have been removed.

Power-Up X/Z-Axis Home Movement and Possible Crash Areas:

• Spindle[1]
• Cross-slide with tool post, riser block, or tool changer[2] 

1. Press and hold [POWER ON] until you see the Haas logo on the screen. After a self-test and boot sequence, the display shows the startup screen. The startup screen gives basic instructions to start the machine. Press [CANCEL] to dismiss the screen. You can also press [F1] to disable it.

2. Turn [EMERGENCY STOP] clockwise to reset it.

3. Press [RESET] to clear the startup alarms. If you cannot clear an alarm, the machine may need service. Contact your Haas Factory Outlet (HFO) for assistance.

4. Close the doors.

Warning: Before you do the next step, remember that automatic motion begins immediately when you press [POWER UP/RESTART]. Make sure the motion path is clear. Stay away from the spindle, tool changer.

5. Press [POWER UP]. The axes move slowly until the machine finds the home switch for each axis. This establishes the machine home position. The control is now in OPERATION:MEM mode. 

Installing a Collect:

1. Open the large operator door.

2. Press the CHUCK button[1] to unclamp the collet. The message “UNCLAMPED” appears on the control screen.

3. Push on the spindle lock pin[2] and turn the spindle by hand until the pin engages and the spindle can not turn.

4. Turn the knurled knob[3] at the end of the drawbar assembly clockwise until you can insert the collet[4] into the spindle nose. The spindle contains a collet anti-rotation pin to align the collet for installation. Turn the collet in the spindle head until you feel the anti-rotation pin engage with the pin slot on the collet.

5. Turn the knurled knob clockwise to draw the collet into the spindle. You will feel the draw bar tighten on the collet threads. 

 Note: Make sure the collet is correctly aligned with the anti-rotation pin. An incorrectly aligned collet can damage the spindle and the collet.

Collet Anti-rotation Pin:

1. Collet
2. Collet anti-rotation pin slot.

Collet Use Tips:

Some collets hold certain materials better than others, so make sure to choose the proper collet for the application (i.e., serrated vs. smooth). Standard collets pull back while they clamp material. If the part outer diameter (OD) varies, pullback (Z-distance) will vary. Because of their design, dead length (exact length) collets position parts more consistently.

Note: Do not try to adjust the length of the draw bar arm air cylinder. Contact Haas Service for adjustment. If roller bearings spin while the spindle turns, contact Haas Service.

Inserting a Workpiece:

1. Put a part into the open collet.

2. Turn the knurled knob clockwise until the part is tight in the collet, then loosen the knob about one half-turn.

3. Press the CHUCK button. Make sure that the part is clamped in the collet.

Warning: If the part is in place, but the collet and the part are not tight, do not operate the spindle.

4. Next, find the correct clamping force for your stock:

• Press the CHUCK button to unclamp the collet (‘UNCLAMPED’ will be displayed on the screen).
• Turn the knurled knob slightly; clockwise to tighten, counterclockwise to loosen.
• Press the CHUCK button to clamp the collet.The part is properly clamped when the draw bar arm hesitates during clamping, then continues to the end of the piston stroke. The mechanism makes a distinct sound when it clamps.

Warning: If the arm does not go to full stroke, the collet has not properly clamped the part. The machine will not start the spindle until the micro switch[5] is tripped when the collet is clamped.

 Warning: If the arm does not hesitate while the part is clamped, the part will not be clamped tightly and it may spin when the tool makes contact. The part may also come out, causing damage or injury.

5. Do a couple of test clamps to make sure the collet is set at the correct tension.

Note: A standard 5C collet has a maximum adjustment range of only around 0.010". Part diameter variation or bar stock variations may therefore cause improper clamping. Good machining practices include regular inspection of bar stock diameter and/or adjustment of the collet.

6. Make sure to disengage the spindle lock pin before you try to operate the spindle.

Removing a Collet:

1. Open the large operator door and press the CHUCK button to unclamp the collet.

2. Push on the pin and turn the spindle by hand until the pin engages and the spindle can not turn.

3. Turn the knurled knob counterclockwise to begin loosening the collet. If there is bar stock in the collet, remove it from the collet as soon as it is loose enough.

4. Keep turning the knurled knob until the collet is loose, then remove the collet from the spindle. Collet Use Tips Some collets hold certain materials better than others, so make sure to choose the proper collet for the application (i.e., serrated vs. smooth). Standard collets pull back while they clamp material. If the part outer diameter (OD) varies, pullback (Z-distance) will vary. Because of their design, dead length (exact length) collets position parts more consistently.

Installing a Chuck:

1. Engage the spindle lock pin while you do this procedure.
2. Attach the chuck to its back plate with the Socket Head Cap Screws (SHCS) supplied in the kit. Torque the SHCS to 25 ft-lbs.

Installing a Chuck:

1. Socket-head cap screw (SCHS)
2. Face plate
3. Chuck.
4. Gently turn the assembly onto the spindle nose until it seats against the spindle shoulder. Tighten the chuck with a strap wrench to approximately 70 ft-lbs.

Chuck Alignment: Follow this procedure to eliminate runout in the chuck.

1. Place a precision test bar in the chuck.
2. Set a dial indicator against the test bar and rotate the chuck.
3. Use the chuck adjustment screws to align the chuck until the dial indicator reads zero.

Chuck Removal:

1. Engage the spindle lock pin.
2. Use a strap wrench to unscrew the chuck. To avoid damaging the chuck, do not pry against the chuck jaws.

ATT8 Turret Detail:

1. Turret
2. Tool-Retention Screws
3. Tool Holder
4. Tool

Note: The ATT8 has a 1/2 inch turning tool height from the top of the turret.

To set up the ATT8 turret:

1. Loosen the tool-retention screws[2].
2. Put the tool[4] into the tool holder[3] and tighten the tool-retention screws[2].

Caution: It is not recommended to use the ATT8 tool changer on a machine with the tailstock option.

Caution: If you use the air gun to remove chips and coolant from the turret, do not blow air into the ring cover at the base of the turret. Compressed air can force chips and coolant into the mechanism. This damages the unit.

Use this program to test the tool changer:

Note: Use T-address codes to operate the tool changer. For example, T303 rotates the tool changer to the number 3 tool position, and uses offset 3. Add the T-address code to the program like the other lines of code. Refer to the Lathe Operator’s manual for more information on the T-codes and tool offsets.

Note: The bar pusher can only be used with a collet. Do not use a chuck with the pusher option.

To set up the bar pusher:

1. Check the bar pusher air pressure gauge[1], it should read 0 PSI/BAR. If not press [RESET] on the control.

2. With the operator door open, rotate the bar pusher tube to the load position.

3. Insert one piece of bar stock into the pusher tube[2] and install a two piece support collar [3] in the end of the pusher tube.

Note: The bar stock should have a slight chamfer on both ends to prevent binding and inconsistent push lengths. For bars over 0.750” add a chamfer to make sure they fit correctly on the cone.

4. Manually feed the bar using the manual feed switch[4]. Adjust the pusher air regulator[5] until the bar pushes out smoothly. Larger bar stock will require more air pressure. Stop feeding the bar when adjusted and push it back into the pusher tube.

5. Rotate the bar pusher tube back to the run position. Using the manual feed switch[1] manually feed the bar stock into the collet to the position where it will be cut off[2]. Turn the knurled knob clockwise[3] until the part is tight in the collet, then loosen the knob about one half-turn. Press the clamp button to clamp the collet[4]. The part is properly clamped when the draw bar arm hesitates during clampling, then continues to the end of the piston stroke. The mechanism makes a distinct sound when it clamps.

Warning: If the part is in place, but the collet and the part are not tight, do not operate the spindle.

 Warning: If the arm does not go to full stroke, the collet has not properly clamped the part. The machine will not start the spindle until the micro switch is tripped when the collet is clamped.

Warning: If the arm does not hesitate while the part is clamped, the part will not be clamped tightly and it may spin when the tool makes contact. The part may also come out, causing damage or injury.
