About This Machine
Foreword
"The screw cutting engine lathe is the oldest and
most important of machine tools and from it all
other machine tools have been developed. It was
the lathe that made possible the building of the
steamboat, the locomotive, the electric motor, the
automobile and all kinds of machinery used in
industry. Without the lathe our great industrial
progress of the last century would have been
impossible." —How To Run a Lathe, 15th
Edition, South Bend Lathe.
The lathe represented in this manual is a
modern day version of the screw cutting lathes
that trace their roots back to the 1700's, which
were themselves technological improvements of
the bow lathe that can be traced back thousands
of years to the ancient Egyptians.
Now, almost 300 years later, these modern
"screw cutting" lathes are not just a piece of
refined machinery, but a culmination of human
ingenuity and knowledge embodied into the
design and synergy of thousands of interworking
parts—some of which represent the life's work
and dreams of many inventors, mechanical
engineers, and world-class machinists—including
the likes of Leonardo da Vinci, Henry Maudsley,
and the founders of South Bend Lathe, John and
Miles O'Brien.
And now the torch is passed to you—to take
the oldest and most important type of machine
tool—and carry on the tradition. As the operator
of a South Bend Lathe, you now join the ranks
of some very famous and important customers,
such as Henry Ford, who used the machines he
purchased to help him change the world.
Features
Looking down the bore of the Big Bore Lathes is
like looking straight down the barrel of a huge
cannon. With an extra-large 9" spindle bore and
inside/outside spindle noses for mounting chucks
on both sides of the headstock, these lathes can
handle monster-sized workpieces such as large-
diameter oil pipes or hydraulic cylinders. They
are exquisitely built with ultra-tight tolerances,
and the headstocks and gearboxes are assembled
in a laboratory-like environment to ensure
absolutely pristine bearings and fittings for a
lifetime of rugged use. Each lathe is built to
order with chucks precision-fitted onto the lathe
at the factory.
The beds of these lathes are constructed with
Meehanite castings that are hardened and
precision-ground in the traditional three V-way
prismatic design—long used on South Bend
Lathes for its accuracy, durability, and rigidity.
The headstock features gear levers, and the
carriage includes an adjustable clutch that
disables automatic carriage feed when it contacts
the included 4-position apron stop or in the event
of a crash.
To further ensure a high degree of accuracy,
these lathes are equipped with high-quality
spindle bearings and a Fagor DRO. The spindle
nose is A2-15 with an MT#7 taper. The tailstock
has an MT#6 taper and 10" of quill travel. For
easy end drilling of large diameter holes and
chamfers with the tailstock handwheel, a 2-speed
gearbox is incorporated in the tailstock.
Also included is a remote-mounted control panel
on the carriage, and a rapid traverse motor with
controls for moving the cross and longitudinal
feeds for quick tooling positioning and returns.
These lathes are equipped with two types of
brakes: a band-style foot brake and an electric
motor brake.
Capabilities
These Big Bore Lathes are built for daily use
in busy gas and oil field settings. Loaded with
many nice features and high-precision parts,
these lathes excel when long drill pipes, shafts,
and flanges need to be surfaced, chamfered,
or threaded. Thick castings, heavy mass, and
quality construction throughout provide the
necessary brawn for demanding production and
manufacturing tasks.
