5. When locating the base assembly into the flange bore, the need will arise to level
the base to check the machine is parallel to the flange. To check, attach and
secure a dial test indicator (DTI) to the toolpost, connect the machine to the air
supply (refer to section 5.3.1 and observe all Warnings and Cautions) and set the
gearbox traverse selector to neutral (N). Open the air control valve and slowly
move the surfacing arm around the flange. Check the DTI for variations and
adjust the swash of the machine, if necessary, by tightening the grub screw in
the centre of each setting strap plate against the flange face thus pulling the base
up the bore. Recheck the base for rigidity.
6. Should the degree of accuracy required be greater than that achievable by
location of the machine's spigot in the base unit, the machine can be centred
relative to the base by unscrewing the centre spigot from the machine base plate
and fitting a pusher plate to each of the bosses on the base unit (Fig. 15). The
machine can then be adjusted as required, by nipping the M12 hexagon head
screws to hold the position but allowing the machine to be pushed by turning the
adjusting screw on each of the pusher plates. Using the DTI for comparison
against the datum feature, check the base for alignment when the desired
accuracy is achieved, secure the machine and check again.
WARNING: DO NOT REMOVE THE SETTING PLATES UNTIL THE MACHINE IS
SECURE AND ALL ADJUSTMENTS ARE COMPLETE.
