*
Crank the motor by hand and bring the turret in de-clamped position. Declamped position can be sensed
by the reduction in pressure during hand cranking. If in doubt connect 24V DC supply to the turret. 'OFF'
condition of LED on proximity switch also indicates de-clamped position. Rotate motor shaft further two
revolutions in same direction. Slightly tap the bolt heads (15) using allen key to release the Ringfeder clamp.
(Insert allen key in bolt head socket and tap it with hammer).
*
In this position, it is possible to turn the indexing flange (27) by hand. If necessary, force the angular movement
of the flange to loosen the grip of ringfeder clamps. Bring the Indexing flange (along with tool disc, if it is not
removed) in proper angular position. Reference mark made on the coolant flanges (26) and (24) can serve
as a rough guide.
CAUTION : * If you make a mistake of one tooth, the tool disc position will change by 5°. The tool disc
will then sit in an angular position, making it impossible to align the tools.
* If you do not take care, you may position the indexing flange (and tool disc) at some other
tool position. In such a case, tool position number, and encoder feedback will not match.
*
Crank the motor and bring the turret in clamped position, as indicated by proximity switch LED.
*
Now tighten the bolts (15) to clamp indexing gear (13) on the spindle. Bolts should be tightened in gradual
manner, in 3 to 4 stages. Tighten opposite bolts in sequence (1,5,2,6,3,7,4,8 ).
*
Crank the motor by hand in both directions, and check for the correct indexing movement.
*
Fit flange (18).
*
Now the encoder can be fitted back in position.First roughly position the slot in drive dog (23) in the same
angular orientation as the pin (22) on the spindle.Then gently fit the encoder in position ensuring that slot
fits properly on the pin. Clamp the encoder in position,such that the orientation marks on encoder and flange
match.
*
Supply 24V DC power to encoder, and check that the encoder feed back position matches with the actual
position of tool disc.
*
Follow the procedure given on page (14) to adjust the encoder in proper position.
*
Fit back the cover (60).
*
Put the lubricating oil (Page 11 ).
*
Run the turret with power to check for proper functioning.
