INTRODUcTION

functional Overview

the primary purpose of the metal lathe is to
make concentric cuts in metal stock. With the
lathe, round stock can be made perfectly con-
centric, threaded, drilled, knurled, bored, tapered,
etc. square stock can be made into precision
round shafts used for axles, spindles, leadscrews,
punches, etc.
the maximum size of workpiece a lathe can cut
is determined by the swing, which is the distance
from the center line of the spindle to the bed,
and the throw, which is the maximum distance
between the tailstock and the spindle. however,
this lathe features an open spindle that allows lon-
ger workpieces to extend through the headstock.
during typical operations, the lathe cuts with a
fixed cutting tool that is positioned against a rotat-
ing workpiece. to rotate a workpiece, the operator
centers it on a clamping device called a chuck
or faceplate, then securely clamps the chuck or
faceplate to the spindle so it will not fly loose dur-
ing operation.
the spindle connects to the motor through a
series of pulleys that control the speed the spindle
can rotate, which allows the operator different
options for cutting based on the type of metal and
size of workpiece.
the cutting tool is mounted on a tool post, which
is positioned by three different bases that move
linearly in their own designated direction. the
bottom base is the carriage, which moves left and
right, and is equipped with a power feed system
for automated cutting and threading operations.
the middle base is the cross slide, which moves
in and out. the top base is the compound slide,
which moves diagonally.
the lathe is also outfitted with a support device
called a tailstock. the tailstock is mounted on the
lathe bed opposite of the spindle, and it moves
toward or away from the spindle and can be
locked against the bed to firmly support the end
of a long workpiece.
