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

Note: Before you do this procedure, remove all shipping brackets and steady rest if equipped from the machine. Make sure that possible crash areas, such as the spindle, cross-slide, and tailstock, are clear.

Power-Up Cross-Slide Home Movement and Possible Crash Areas:

• Spindle[1]
• Cross-slide with tool post, riser block, or tool changer[2] 
• Tailstock[3]

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]. Make sure the motion path is clear. If equipped, the steady rest cannot be installed between the cross slide and tailstock during the zero return procedure. Stay away from the spindle, cross-slide, and tailstock.

5. Press [POWER UP]. The axes move slowly until the machine finds the home switch for each axis. This establishes the machine home position. A flashing message, INSTALL TOOL 1 PRESS CYCLE START, prompts you to install tool 1 and press [CYCLE START].

 Note: Some options, such as TT-4 or ATT8, disable the Power Up function. In this case, the zero return menu will be used to home the machine.

6. Check clearance before moving each axis. If needed, push [HANDLE JOG] and move axes to a safe position. Remove tools if necessary. If the eHandwheel is installed the pendant jog wheel is only used to scroll through the control. You must use the eHandwheel to jog the axes if installed. Zero return each axis separately. Press [T], and only the tool changer will find home. c) Press [A], and the Tool Turret will find home first then X and last the Z-axis. The control is now in OPERATION:MEM mode. 

eHandwheel Overview:

1. Power Feed
2. Handle Jog
3. Jog Increment
4. Power Feed Rate
5. Rapid Feed

Note: When the eHandweel is installed the pendent jog wheel will only scroll through the control page. It cannot be used to jog the machine.

Note: Feed Rocker switches only work when the spindle is turning or while Rapid Feed is pressed. 

Jog Chamfer:

Use the Jog Wheels to jog the tool to the starting point. While in the operator tab in handle jog mode, press [F3] to enable the chamfer option. The chamfer icon will appear on the screen. Enter a number value and press [F2] to set the chamfer angle. Use the Power Feed rocker switches to jog in or out of a chamfer. Press [F3] to exit chamfer mode.

TL-1/2 Tailstock:

• Quill Clamp Lock[1]
• Base Lock Wrench[2]
• Quill Adjustment Wheel[3]

To operate the tailstock:

1. Loosen the clamp bolt at the base of the tailstock casting with the Base Lock Wrench[2]. Move the wrench counterclockwise to loosen.

2. Position the tailstock base manually, then tighten the clamp bolt at the base of the tailstock casting with the Base Lock Wrench[2]. Move the wrench clockwise to lock.

3. To drive the quill in and out, rotate the quill clamp lock[1] away from the spindle and rotate the hand wheel on the rear of the casting[3] counterclockwise and clockwise.

Note: The TL-1/2 tailstock has a #4 Morse taper (MT4).

TT-4 Turret Detail:

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

To set up the TT-4 turret:

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

Caution: There is a clearance of 0.25" (6 mm) between the bottom of the lower TT-4 plate[1] and the top of the servo-motor cover. Do not use a tool that extends below the top of the servo-motor cover. Use a boring-bar holder[3] of the type shown.

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.

Make sure the tailstock[2] has sufficient clearance around the servo motor cover. To prevent interference between the tailstock and the servo-motor cover, extend the tool holder farther out of the turret.

TT-4 Turret and Servo-motor Cover Clearance:

1. Tailstock centerline
2. Tailstock
3. Clearance
4. Servo-motor Cover

Make sure the clearance[3] between the tailstock centerline[1] and the edge of the servo-motor cover[4] and the turret is more than 1.78" (45 mm).

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.

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.

To operate the C-type steady rest:

1. Turn the roller lock screws[1] to loosen the rollers.

2. Retract the rollers by turning the adjustment screws[2].

3. Clamp the workpiece into the chuck.

4. If a tailstock is to be used, engage the tailstock live center and engage the tailstock brake.

5. Turn the steady rest roller adjustment screws[2] to move the rollers against the workpiece.

6. Tighten the roller lock screws[1] to secure the rollers in place.

Note: Haas recommends that you do not place material with a rough finish in the steady rest. The steady rest holds more securely on a workpiece with a smooth surface.

7. Place a dial indicator on a Z-Axis linear guide and position the indicator tip near the outside edge of the workpiece.

8. Turn the workpiece by hand and check for deflection in the part.

9. Adjust and tighten the steady rest rollers as necessary.
