Adjust the Power Drawbar

If you have not yet done so, you must adjust the Power Drawbar. Complete the following steps in the order listed:

Adjust the Drawbar Tension

This adjustment sets the highest possible drawbar tension while still allowing the Power Drawbar cylinder to release the tool. For information, see"About Drawbar Tension" (page 22).

NOTICE! After the initial installation, you must examine the drawbar tension weekly. During periods of heavy use, examine the drawbar tension more frequently. If you don't, there's a risk of tool pull-out.

To adjust the drawbar tension:

1. Put an empty Tormach Tooling System (TTS) tool holder into the collet.

2. While using one hand to support the tool holder, use the other to push the Release Tool button.

3. Depending on whether the tool holder releases or not, do one of the following:

   1. If the Tool Holder Releases Tighten the Power Drawbar in quarter-turn increments with two adjustable wrenches. After each turn, push the Release Tool button. Stop when the tool holder does not release. Then, loosen the Power Drawbar one quarter-turn with two adjustable wrenches.

   2. If the Tool Holder Doesn't Release Loosen the Power Drawbar in quarter-turn increments with two adjustable wrenches while pushing the Release Tool button. Stop when the tool holder releases.

Make a visual reference to help you set or adjust the drawbar tension in the future: use a paint pen to make a witness mark on both the head of the drawbar and the end of the spindle.

About Drawbar Tension

While machining, the Tormach Tooling System (TTS) collet holds a Tormach Tooling System (TTS) tool holder in the spindle by applying a clamping force to both the shank and the shoulder of the tool. The tension force that is applied to the drawbar pulls the Tormach Tooling System (TTS) collet into the spindle taper, which then applies the clamping force to the Tormach Tooling System (TTS) tool.

The force on the drawbar — known as drawbar tension — is applied differently depending on the tool changing method:

• Automatic (using the Power Drawbar) Tension is applied by the compressed spring washers.

• Manual Tension is applied when you tighten the drawbar into the collet using a wrench.

Adjust the Initial Setup

In this adjustment, you'll verify that there's enough clearance between the end of the drawbar and the Power Drawbar cylinder.

NOTICE! If you don't do this adjustment, there's a risk that the drawbar can loosen, or that operations can be louder than normal.

1. Examine the space between the hex head screw on the Power Drawbar cylinder's rod and the top of the drawbar.

2. Verify that the gap is between 3/64 in. and 1/8 in. (1 mm and 3 mm). Depending on the size of the gap, do one of the following:

   1. Between 3/64 in. and 1/8 in. (1 mm and 3 mm) You have completed adjusting the initial setup. Go to Operation.

   2. Less Than 3/64 in. (1 mm) Go to Step 3.

3. Disconnect the shop's air supply from the Power Drawbar button.

4. Pull out the quick-release pin.

5. Pivot the Power Drawbar cylinder assembly to the left so that you can access the Power Drawbar cylinder's rod.

6. Remove the hex head screw on the Power Drawbar cylinder’s rod with an adjustable wrench, and set it aside.

7. Remove the M16 washer from the Power Drawbar cylinder’s rod, and set it aside.

8. Put the hex head screw back in, and then tighten it completely with an adjustable wrench.

9. Pivot the Power Drawbar cylinder to the original location.

10. Push in the quick-release pin.

11. Reconnect the shop's air supply to the Power Drawbar button.

12. Examine the space between the hex head screw on the Power Drawbar cylinder’s rod and the top of the drawbar.

13. Verify that the gap is between 3/64 in. and 1/8 in. (1 mm and 3 mm). Depending on the size of the gap, do one of the following:

    1. Between 3/64 in. and 1/8 in. (1 mm and 3 mm) You have completed adjusting the initial setup.

    2. Less Than 1/8 in. (1 mm) Go to Step 14.

14. Find the three provided M14 flat washers.

15. Put one M14 flat washer under each mounting post on the Power Drawbar cylinder.

Make Final Alignments to the Automatic Tool Changer (ATC)

Complete the following steps in the order listed:

Adjust the Tool Tray Load Position

1. Verify that there's no tool in the spindle.

2. From the PathPilot interface, on the ATC tab, select Ref Tool Tray.

The tool tray spins.

NOTE: You're only required to reference the tool tray once, unlike the mill axes’ referencing procedure.

3. Select Go to Tray Load Position.

4. When prompted, select OK.
   The tool tray moves forward.

5. Put the tool holder with the rod into the fork.

6. From the PathPilot interface, slowly jog the Z-axis down (-Z) to bring the spindle nose toward the tool in the tool tray.

7. Make sure that the tool’s shank is aligned concentrically with the collet in the spindle.

8. If the tool's shank isn't aligned, do the following:

   1. Adjust the Alignment of the Tool in the Y Direction (toward or away from the Z column) Determine if the tray must move clockwise or counterclockwise. From the PathPilot interface, in the ATC tab, either select -- to step the tool tray counterclockwise or ++ to step the tool tray clockwise.

b. Adjust the Alignment of the Tool in the X Direction (left or right) Determine if the tray must move left or right. Use two wrenches to loosen the jam nut on the end of the cylinder rod, making sure that you don't spin the rod end when adjusting the jam nut. Then, either turn the rod end one-half turn further on to the cylinder rod to move the tool tray to the left, or turn it one-half turn off of the cylinder rod to move the tool tray to the right. Once finished, tighten the jam nut.

Repeat adjustments until the tool's shank is concentric with the collet in the spindle.

9. From the PathPilot interface, on the ATC tab, select Retract.

Verify the Alignment

1. From the PathPilot interface, select Go to Tray Load Position.

2. Slowly jog the Z-axis down (-Z) over the tool’s shank.

3. Verify that the tool’s shank moves freely into the collet.

4. Depending on the tool's shank movement, do one of the following:

• Moves Freely Go to "Set the Tool Change Height" (page 32).

• Doesn't Move Freely This indicates that the ATC is misaligned and you must realign it. Go to "Adjust the Tool Tray Load Position" (page 25).

Set the Tool Change Height

1. From the PathPilot interface, slowly jog the Z-axis down (-Z) over the tool. Stop jogging when the spindle nose just makes contact with the shoulder of the tool holder.

2. On the ATC tab, select Set TC POS.

The tool change position is set.

Adjust for Rotational Play

There's a small amount of rotational play built into the Automatic Tool Changer (ATC) carousel. This play allows for some misalignment during tool changes, and you must adjust for it in both directions. The taper on the tool shank also helps align the tool during a tool change.

To adjust for rotational play:

1. From the PathPilot interface, on the ATC tab, select Tray Fwd to rotate the tray clockwise (forward) one full tool slot.

2. Select Tray Rev to rotate the tray counterclockwise (backward) one full tool slot.

3. Verify that the tool’s shank is aligned with the collet in the spindle.

4. Depending on the alignment, do one of the following:

   1. Aligned You have completed aligning the ATC. Remove the tool from the fork. Go to Step 5.

   2. Not Aligned You must readjust the tool tray rotation. Go to "Adjust the Tool Tray Load Position".

5. From the PathPilot interface, on the Main tab, drag the Maxvel Override slider to the left. This reduces the maximum velocity by the percentage shown.

6. Do a test tool change. Because the maximum velocity is reduced, it's easier to verify the alignment of the ATC and stop the machine if further adjustment is required.

Tip! Use the Spacebar key to pause the tool change, if needed.

Operation

NOTE: You must always have a tool holder in the while the machine is not in use. Retracting the Power Drawbar to the clamped position with no tool holder in the will eventually fatigue the , and may shorten its service life. For more information, refer to the Power Drawbar documentation.

1. From the PathPilot interface, slowly jog the Z-axis down (-Z) over the tool. Stop jogging when the spindle nose just makes contact with the shoulder of the tool holder.

2. On the ATC tab, select Set TC POS.

The tool change position is set.

Switch to Manual Tool Changes

From the PathPilot interface, on the Settings tab, select the Manual Tool Change radio button.
The Automatic Tool Changer (ATC) is prevented from making tool changes.

Troubleshooting

If you're having issues with the ATC, read the following sections:

Lubricate the Linear Rails

The linear rails are self-lubricating, so you don't need to lubricate them. If, after initial installation, you hear chatter from the linear rails, apply a thin layer of way oil to the linear rails.

Replace the Plastic Screws on a Fork

The plastic screws that hold the fork to the tool tray are designed to fail under greater-than-normal loads: when a tool crashes, the plastic screws snap to prevent damage to the Automatic Tool Changer (ATC). If the plastic screws that hold the fork to the tool tray break, you can replace them.

To replace the plastic screws on a fork:

1. Remove the broken screws from the fork.

2. Secure the fork to the tool tray with two of the included plastic screws. Make sure that the groove on the fork faces the machine table.

NOTICE! Don't use metal screws to replace broken screws on an ATC fork. If you do, it could cause machine damage.

You must adjust the tool tray rotation again: go to "Adjust the Tool Tray Load Position"
