Using Centers
The dead center is used in the tailstock and lathe spindle
to support workpieces. When used in the tailstock, make
sure to keep the MT#3 dead center tip and workpiece
lubricated to prevent tip galling.
This lathe/mill is also supplied with an MT#5 dead center
that fits into the lathe spindle taper.
To install a dead or live center, do these steps:
1.
Feed the quill out about 1" and insert the MT#3 dead
center (
Figure 30
). The mating tapers provide the
locking action.
2.
Move the tailstock into position and lock in place.
3.
Feed the quill into the workpiece.
Note:
Make sure there is a center drilled hole in
the end of the workpiece for the dead center.
4.
Lock the quill into place once the live center and
the part rotate together. The quill may need to be
adjusted during operation.
5.
To remove the dead center, retract the quill until
the dead center pops free.
To install the MT#5 dead center in the spindle, do
these steps:
1.
Remove the chuck from the spindle.
2.
Install the MT#5 dead center in the spindle.
3.
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.
