This is a general description of what machine tools do.

Machine Tools
The LatheThe lathe is used to make round parts, such as shafts and
bushings. The lathe can also make more complicated parts if
the right operations are used.
The milling machine
makes flat surfaces
and mills grooves; by
clamping a round work
piece in a v-block,
keyways or flats can
cut on shafts. With a
rotary table this
machine can also mill
circular grooves and
slots.
The Vertical Milling Machine
The Horizontal Milling Machine
The horizontal
milling machine
has been largely
replaced with the
vertical milling
machine. Like
the vertical mill,
the horizontal
mill can machine
flat surfaces and
grooves but with
a dividing head it
can also produce
gears.
The Upright drill press, as
the name implies, drills
holes. This type of drill
press also has automatic
feed which makes drilling
deep holes much easier.
Upright Drill Press
Radial Arm Drill Press
The radial arm drill press is
used to drill holes in work
pieces too large to fit on a
upright drill press. On this
machine the head unit
slides on the arm, this
allows the machine to drill
multiple holes without
moving the work piece.
If you need a
highly accurate,
extremely flat
surface, the
surface grinder
is the tool you
need. With this
machine
tolerances within
one ten-
thousandth
(0.0001) of an
inch are
possible.
Surface Grinder
CNC (Computer Numerical Control)
CNC machines are
computer controlled
machine tools, and
are generally much
faster than their
manual counter parts.
Turning Center
A turning center is
a CNC lathe.
These machines
have a automatic
tool changer which
speeds up
machining times
tremendously.
Parts produced by
these machines
usually only take a
few seconds to
produce, but larger
parts may take a
couple hours to
finish.
Machining Center
What the Turning center
is to the lathe what the
machining center is to
the milling machine.
From turbines to engine
blocks CNC mills can
produce some very
complex parts. With
their automatic tool
changers they are much
faster than manual
milling machines.
