6.1.5 Indexer Encoder Re-Alignment
This procedure is necessary only if the indexer does not return to a true home position
after initializing with Service Code 147. If the encoder is misaligned the turret will
consistently be off by some angle. In order to perform the operation it may be necessary
to use two people. One will adjust the encoder while the other watches the strobe 2
light inside the black box on top of the chip enclosure. If the encoder is misaligned, a
LED labeled strobe 2 will be lit.
1.
Remove the 4 screws that hold the back cover onto the indexer. The encoder is mounted
to the far right of the indexer if you are at the front of the machine and facing it. Please
refer to the Dorian manual that is included with the machine for an illustration.
2.
If initialization does not work, attempt to index the indexer until it sits in a true
position. A true position means the tool stations are parallel to the crosslide. This
can be done by reversing the air lines on the indexer. Reverse the blue and red air
lines and then use a breaker bar or piece of square stock to rotate the turret
manually to a true position. Make sure to reverse the air lines back when complete.
It will be obvious when the indexer is back to a true position. The indexer moves in
approximately 15° increments.
3.
Using an allen wrench, loosen the setscrew holding the encoder onto the shaft.
4.
Rotate the encoder with the allen wrench until the strobe 2 light turns off in the black
box. Carefully tighten down the setscrew making sure not to move the encoder. If
the encoder moves, the number in the box will disappear and it will be necessary to
re-align the encoder.
5.
Reassemble the unit.
6.1.6 Indexer Maintenance
Dorian recommends that the indexer be lubricated twice a year after the first year. The
worm and worm gear should be lubricated with quality lithium based grease every 6
months after the first year. Remove the side cover, top cover and stepper motor and
grease the gears. When re-mounting, be sure the O-ring and side seal are intact so that
no coolant can enter the turret. Refer to the Dorian manual that is supplied with each
machine for more information and drawings.
6.1.7 Warranty Issues
Dorian warrants the Dorian Indexer for 1 year. If it is determined that there is a problem
with the indexer it will need to be sent back to Dorian for repair. Please refer to the
Dorian manual that was shipped with the indexer.
