Tool Changer (TC) Alignment Verification
TC alignment must be verified before loading any tools. Any adjustment or change to the machine level will
affect TC alignment. Incorrect TC alignment can result in dropped tools, damaged waycovers, cambox damage,
excessive wear, and damage to the TC double-arm.
Verify tool changer alignment before operating the mill.
As a safety precaution the Service technician must ensure that the tool changer is aligned properly to the
spindle. The installation and leveling of a new machine will affect the tool changer alignment. Use the following
instructions to verify alignment. Do not load any tools into the tool changer or spindle until alignment is com-
plete.

1. With no tool in the machine, command a tool change. Press Emergency Stop before the double arm
reaches the spindle. This will cause the mill to move the Y and Z axes to the ATC position.
2. Verify the spindle is free to rotate without hitting the double arm. If necessary, use the T/C Recovery
commands to move the arm further from the spindle.
3. Using T/C Recovery, orient the spindle.
4. Using T/C Recovery, rotate the double arm in the forward direction. Continue rotating the double arm
until it reaches the spindle, then extends approximately 6" (152.4 mm) in front of the spindle.
5. Using the dowel pin as a handle, install the tapered half of the split tool into the spindle. Be careful to
not place your hands in the pinch point between the tool and the spindle. The Tool Release button
operates in a Toggle On/Off mode during Tool Recovery. Press once to activate the Tool Release; press
again to clamp.
6. Remove the dowel pin, and install the second half of the split tool into the end of the double arm in front
of the spindle. It will be necessary to manually press the tool lock plunger (near the center of the shaft
as shown in the Service manual) to allow the spilt tool to be inserted.
7. Using T/C Recovery in the reverse direction, move the double arm back toward the spindle until the
halves of the split tool are approximately 1" (25.4 mm) apart.
