G0492 12" X 36" Combo Lathe/Mill
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:
1.
Feed the quill out about 1" and insert the
MT#3 dead center (
Figure 24
). The mating
tapers provide the locking action.
