Tailstock Positioning
Longitudinal Positioning
To adjust the tailstock longitudinally, do
these steps:
1.
Loosen the tailstock Quick lock shown in
Figure 12 .
2.
Slide the tailstock into position along the
bed, then tighten the clamp nut to secure the
tailstock in the new position.
Offset Positioning
The two offset adjustment screws (
Figure 12 )
position the tailstock away from the center line
for turning tapers.
To offset the tailstock to the left of the center
line, do these steps:
1.
Loosen the tailstock Quick lock, and using a
3mm hex wrench, loosen the lock screw.
2.
Using a 6mm hex wrench, loosen the front
offset adjustment screw.
3.
Tighten the rear offset adjustment screw to
move the tailstock to the desired position, then
tighten the front offset adjustment screw.
4.
Tighten the lock screw and clamp nut.
To offset the tailstock to the right of the
center line, follow the instructions above but
reverse Steps 3 & 4.

Cross Slide
The cross slide moves perpendicular to the
longitudinal axis and features a scale on the
handwheel that displays graduations of one
thousandths of an inch (0.002") or 0.05mm.
To adjust the cross slide, do these steps:
1.
Using the handwheel, back the cross slide
away from your starting point by at least 0.30,
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 accurate.
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 13 . 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.
