Objective:To study Lathe machine, Parts, Working principle, Operations and its Type.Introduction:The machine tool that is used to remove unwanted metals from the work piece to give the desired shape and size is called Lathe machine. Lathe machine is also known as “Center Lathe” because of two centers between which the job can be held and rotated.Lathe is one of the most important machine tools in the metal working industry. A lathe operates on the principle of a rotating work piece and a fixed cutting tool. The cutting tool is feed into the work piece, which rotates about its own axis, causing the work piece to be formed to the desired shape. Lathe machine is also known as “the mother/father of the entire tool family”. The lathe machine is one of the oldest and most important machine tools. As early as 1569, wood lathes were in use in France. The lathe machine was adapted to metal cutting in England during the Industrial Revolution.
Parts of lathe machine:The main parts of lathe machine are:Bed:The bed is the main body of a lathe which provides supports to all parts of the machine.The bed is heavy, rugged casting which is mounted on the working parts of the lathe.Head Stock:Head stock is the main body parts which are placed at left side of bed. It is serving as holding device for the gear chain, spindle, driving pulley etc. It is also made by cast iron.
