AX48-120 Flange Facing Machine
29
DO NOT LIFT THE BASE USING THE BAR IN THE CENTRE OF THE UNIT. THE
BAR IS FITTED TO LOCATE THE MACHINE CENTRE SPIGOT AND IS NOT
INTENDED TO TAKE THE WEIGHT OF THE BASE ASSEMBLY. ALWAYS USE
THE DEDICATED LIFTING POINTS.
If the machine is to be used on a vertical flange then follow the lifting instructions in
section 5.2.7.
8. When the base assembly is correctly positioned within the bore, secure in the
bore (working on opposite pairs of jaws – using the upper jaws) by tightening the
ram bolts equally to maintain position.
5.2.3 Centralising the base within the bore
1. Position the clocking tower into spigot hole in the centre of the base unit (Fig. 15)
and slide the clocking bar into the pivoted bracket. Adjust the position of the
clocking arm to suit the flange diameter and clamp in position. Fit the spike to
the outer end of the bar and secure with the socket head screw.
2. Using the spike select the datum diameter (i.e. raised face, 'V' groove or bolt
holes) and rotate the clocking arm. Check the spike follows the datum and adjust
if necessary. To adjust the base, tighten and slacken opposite sets of ram bolts -
upper jaws (similar to a four jaw chuck operation) securing the unit progressively
in the flange until the desired accuracy has been achieved. It is possible to
achieve concentricity within 0.25mm with care.
3. Tighten up all eight lower jaw units to ensure the base is secure in the bore.
Recheck the base is still centred.
4. Remove the clocking tower and arm.
During centralising ensure that all the setting straps are fitted. When centralised,
the base should be tight enough within the bore to support its own weight and that
of the turntable assembly.
NEVER SLACKEN A RAMBOLT UNLESS ALL SETTING STRAPS ARE FITTED.
