Lathe Machine

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.

Specification of a Lathe Machine

Specification of a Lathe Machine

Specification of a lathe machine is utterly dependent on the specifications required to turn a job. It is advisable to know the type of job, job maximum diameter & of course job length. So, when it comes to lathe machine specification there are may things which should be confirmed with the supplier to ensure machine fits your need.

Here are the list of few important things:
 
a.    Swing or maximum diameter that can be rotated over the bed ways.
b.    Maximum length of the job that can be held between head stock and tail stock centers
c.    Bed length, which may include head stock length also.
d.    Maximum diameter of the bar that can pass through spindle or collect chuck of lathe.
