Understanding Lathe Machine
Turning is one of the most common of metal
cutting operations. In turning, a work piece is rotated about its axis as
single-point cutting tools are fed into it, shearing away unwanted material and
creating the desired part. Turning can occur on both external and internal
surfaces to produce an axially-symmetrical contoured part. Tolerances are the
most critical aspects in lathe machines and at Preet Lathe Udyog we take care
of tolerances to meet customer's job accuracy.
Parts ranging from pocket watch components to large diameter marine propeller shafts can be turned on a lathe. The capacity of a lathe is expressed in two dimensions. The maximum part diameter, or "swing," and the maximum part length, or "distance between centers." Customization of lathe machine in Batala, India by Preet Lathe is possible hence distance between the centers can be customized.

The work may be held on one or by
both its ends. Holding the work by one end involves gripping the work in one of
several types of chucks or collets. Chucks are mounted on the spindle nose of
the lathe, while collets usually seat in the spindle. The spindle is mounted in
the lathe's "head stock," which contains the motor and gear train
that makes rotation possible. Directly across from the headstock on the lathe
is the "tailstock." The tailstock can hold the work by either a live
or dead center. Work that is held at both ends is said to be "between
centers." Additionally, longer work pieces may have a "steady rest "mounted
between the headstock and tailstock to support the work. Typically work-pieces
are cylindrical, but square and odd shaped stock can also be turned using
special chucks or fixtures.
Lathe cutting tools brought to
the work may move in one or more directions. Tool movement on the engine lathe
is accomplished using a combination of the lathe's "carriage",
"cross slide", and "compound rest". The carriage travels
along the machine’s bed ways, parallel to the work-piece axis. This axis is
known as the "Z" axis. Motion perpendicular to the work is called the
"X" axis. On an engine lathe this motion is provided by the cross
slide mounted on the carriage.
