The insertion head casting height adjustment sets the distance from the
bottom of the plate under the CTA to the top of the rotary table. Failure to
correctly make this adjustment may cause interference between the CTA and
the components on the workboard.
Prerequisites:
Plate has been squared to the upper frame.
Comments:
When attempting to set the head height to the rotary table, do not change the
plate settings. The plate settings are set up at the factory and would require
Procedure:
1.Power down the machine and perform Lockout/Tagout according to local procedures.
2.Loosen the 4 mounting bolts on the head drive casting just enough to allow the casting to slide on the plate.
3.Position the positioning system so that the rotary table support bearing is under the CTA transfer plate.
4.Place the gauge block 34,37 mm (1.353 in.) next to the rear rotary table support bearing (reference point), adjust the setscrew (3/16 allen wrench) until the gauge block slides under and back out from below
the CTA transfer plate with only a slight amount of friction. Check the other side of the CTA transfer plate the same way.
5.After the correct distance has been set, retighten the four head casting bolts.
6.Recheck the setting. If the setting has shifted (become more or less than
it should be), repeat steps 1 through 4. If the setting has not changed,
apply torque seal over the set screw threads.
End of procedure.
