TROUBLESHOOTING
If you're having issues with the ATC, read the following sections:
Lubricate the Linear Rails
Replace the Plastic Screws on a Fork
Install the ATC Carousel Plate Spacer
Turn Over the Tool Forks
If the ATC is moounted too high on the machine column for the spindle nose to clear the Tormach Tooling System
(TTS) shank after completing the alignment procedures in the owner's guide, you may need to make adjustments
to lower the tool in the ATC carousel. First "Install the ATC Carousel Plate Spacer" (below), and then, if necessary,
"Turn Over the Tool Forks" (on the next page).
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.
3. You must adjust the tool tray rotation again: go to "Adjust the Tool Tray Load Position" (page 33).
Install the ATC Carousel Plate Spacer
To lower the tool height in the ATC, you can install the provided ATC Carousel Plate Spacer between the ATC
carousel and the tool carousel plate.
To install the ATC Carousel Plate Spacer:
1. Remove the three bolts that secure the tool carousel plate to the ATC carousel and set them aside. Then, set
aside the tool carousel plate.
Note: There are two sets of three bolts provided with this kit. You'll use one set to replace the
original bolts securing the tool carousel plate to the ATC carousel.
