not supported at the free end. Micrometer reading at each end of the
turned length (at A and B of Fig.4) should be the same.
To correct a difference in readings, slacken and release the
four-headstock hold-down screws (J) shown in Fig.4 and adjust the
set-over screw (K) beneath the headstock. Then tighten all screws, after
adjustment and repeat the test-cut/micrometer-reading sequence until
micrometer readings are identical, so machine now cutting
absolutely parallel.
The Importance and Methods of Spindle Leveling Adjustment
1. Switch on to make the Spindle turn while the
Spindle is set up at 1170r.p.m. By putting the palm of
the left hand on the Headstock cover to fell its chatter.
An unrevealing Spindle will lead to lathe chatter.
Move Leveling Block (either “A” or “B”) left or right
to adjust until your left hand feels the minimum
chatter.
2. Afterwards, change the Spindle speed to 1800r.p.m. or
770r.p.m.and check the Leveling with the same way as we did at
770r.p.m.by adjusting the Leveling Block “A” or “B”.
8. Lathe Alignment Part.2
Using a 12in. (305mm.) ground steel bar fitted between headstock
and tailstock centers, check the alignment by fitting a dial-test indicator to
the topside and traversing the center line of the bar. (Fig.6).
