Lathe machine: Main Parts, Operation and Working

Lathe was actually the first machine tool which came into being as a useful machine for metal cutting. Lathe can be defined as a machine tool which holds the work between two rigid and strong supports, called centres, or in a chuck or Face plate while the lathe revolves. The following are some of the important Parts of lathe machine

There are many types of lathe machine but each machine consist some basic part which are essential for its proper working. These parts are bed, tool post, Chuck, head stock, tail stock, legs, Gear chain, lead screw, carriage, cross slide, split nut, apron, chip pan, guide ways etc. These parts work together to obtain desire motion of tool and work piece so it can be machined. Lathes are generally used in manufacturing technology and in the workshop.

Parts of Lathe Machine:

The lathe consist following parts.

1. Bed

The bed of Lathe acts as the base on which the different fixed and operations parts of the Lathe are mounted. Lathe beds are usually made as single piece casting of semi-steel (i.e., toughened cast iron),with the addition of small quantity of steel scrap to the cast iron during melting; the material ‘cast iron’ facilitating an easy sliding action. In case of extremely large machines, the bed may be in two or more pieces, bolted together to from the desired length.

Lathe Bed are heavy rigid structure which is having high damping capacity for the vibrations generated by machines during machining. The rigid structure will helps to avoid deflections. The guides and ways which are present on the top of the bed will act as rails and supports other parts like tail stock. The bed will be designed in such a way that easily bolted to the floor of the machine shop.
