is achieved.
figure 55 shows the Mt#5 dead centers included
with the lathe. in addition, an Mt#7–Mt#5 tapered
spindle sleeve is included for mounting in the
spindle.
Dead centers
a dead center is a one-piece center that does not
rotate with the workpiece and is used to support
long, slender workpieces in the tailstock.
a carbide-tipped dead center (not included) can
better withstand the effects of friction than a typi-
cal dead center and is best used in the tailstock
where the workpiece will rotate against it. the tip
of a dead center must be generously lubricated
during the operation to avoid premature wear and
maximize smooth operation. Using low spindle
speeds will also reduce the heat and wear from
friction.
Use the dead center in the spindle for operations
where the workpiece rotates with the center and
does not generate friction.
