G0600 20" x 60" Big Bore Lathe
Centers
The dead center is used in the tailstock to support
workpieces. When used in the tailstock, make
sure to keep the dead center tip and workpiece
lubricated.
This lathe is supplied with two MT#5 dead cen-
ters–one is HSS and one is carbide tipped. The
supplied MT#5-#7 sleeve fits into the spindle
taper to hold the MT#7 center.
To install a dead or live center:
1.
Feed the quill out about 1" so that the dead
center can be inserted.
2. Insert the dead center into the quill opening.
Matching tapers provide the locking action
(see
Figure 33 ).

NOTICE
Failure to keep dead center point well
lubricated will damage dead center and
workpiece.
The dead center can also be used in the spindle.
The most common application is when using the
faceplate (see
Figure 34
).
To install the dead center in the spindle:
1.
Remove the chuck from the spindle.
2.
Install the dead center in the spindle sleeve.
3.
Install the sleeve and center into the spindle
opening.
4. Attach the faceplate to the spindle.
Note: When using the dead center in the
spindle, use a lathe dog so that your part will
rotate with the spindle and not spin on the
dead center tip.
3.
Move the tailstock into position and lock in
place with the tailstock lock lever.
4. Feed the quill into the workpiece.
Note: Make sure there is a center drilled hole
in the end of workpiece for the dead center.
5.
Lock the quill into place once the live center
and the part rotate together. The quill may
need to be adjusted during operation.
6.
To remove the dead center, retract the quill
until the dead center pops free.
