cross slide

the cross slide moves perpendicular to the longi-
tudinal axis and features a scale on the handwheel
that displays graduations of one thousandths of
an inch (0.001").
To adjust the cross slide:
1.
using the handwheel, back the cross slide
away from your starting point by at least
0.015", then move the cross slide forward to
your starting point.
Note: This procedure will clear any free
movement (or backlash) in the lead screw so
your handwheel scale reading will be accu-
rate. A small amount of free-play is normal,
and must always be taken into account when
using the cross slide.
2.
hold the handwheel still and turn the scale so
the "0" mark lines up with the "0.000" mark
on the cross slide, as shown in figure 22. as
long as you avoid backlash by continuing to
move the cross slide in the same direction,
the scale on the handwheel will be accurate.

3.
after backing the cross slide away from the
workpiece, remember to clear the backlash
before moving the cross slide forward to the
"0" mark for the next cut.

compound slide
Similar to the cross slide, the compound slide
features a scale that displays graduations of one
thousandths of an inch (0.001"). unlike the cross
slide, the compound slide can be rotated to a set
angle and then it can be moved back and forth
along the axis of that angle.
To adjust the compound slide:
1.
loosen the compound slide bolts shown in
figure 23 to allow it to be rotated.

2.
rotate the compound slide to the angle
needed for your procedure.
3.
tighten the compound slide bolts, and check
the angle again to make sure it did not move
during tightening.
4.
use the compound slide handwheel to move
the tool back and forth along the axis of the
new angle. Similar to adjusting the cross
slide handwheel, make sure the threads are
engaging and all backlash has been cleared
before you set the handwheel scale to "0", or
it will not be accurate.
