*
Disconnect power supply to the tur-
ret.
*
Drain Lube oil, using drain plug (160).
*
Remove back cover (60).
*
Bring the turret in a clamped position
by hand cranking, (refer page 11).
Note down the tool position. Also
make a reference mark by a marker
pen on coolant flange (26) as well as
on coolant ring (outer) (24). Even if
turret clamping is not possible at this
stage follow the next steps.
*
Take out the encoder (61). Do not
disconnect wiring.
*
Remove flange (19) .
*
In the clamped position of the turret,
bolts (15) are in line with the holes
drilled in flange (48). In case of a 12
station turret bolts (15) may not be in
line with the holes. Then crank the
turret through one or two stations to
get the alignment. In case turret clamp-
ing is not possible then rotate the
motor shaft in whichever direction
possible; in some intermediate posi-
tion bolts (15) will be in line with the
holes in flange (48). Use suitable allen
key (6 mm size for BTP-125, 5 mm
size for BTP-100, 80, 63) and loosen
all the bolts.

BI-DIRECTIONAL TOOL TURRETS
18. Adjustment of Ringfeder Clamps
In rare cases, it is possible that accident can occur while the turret is indexing spurious signals in control circuit
can unintentionally start the indexing cycle, causing the turret to index in the middle of a machining operation.
In some controls, a "block search" operation can cause the turret to index to a tool position expected after the
axis are repositioned after block search. If such a 'block search' is made without indexing the turret to a expected
tool no at the end of block search, then the turret tooling can hit a rotating chuck, or work piece, causing an
accident.
In such accidents, the friction joint of Ringfeder slips; and protects the internal mechanism from damage. In
such cases, it is necessary to put back the indexing mechanism into proper orientation by adjustment of ringfeder
clamps.
Such a condition is usually associated with the change in angular position of tool disc in the clamped position
or excessive noise in one direction during indexing.
