Lathe machine Figure 4 3. In a lathe machine, the work piece is rotate against the tool. Bed 8 7. Head stock 3. d) Compound rest. 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. Operations Done by Holding Workpiece Between Centres Turning: It is the most common type of operation in all lathe machine operations. The many components of the typical lathe and the vast assortment of lathe parts create a complex maintenance schedule to ensure peak performance from the machine. Carriage is located between the headstock and tailstock on the lathe bed guideways. Every individual part performs an important task in a lathe. Carriage & Tool Post 5. Now come to its major mounting parts like headstock, tailstock, carriage, compound rest, cross slide, lead screw, feed rod etc. Definition of Lathe Machine. Tail Stock 4. Not to be confused with milling machines, lathes are designed to rotate a workpiece against a tool bit. Thread cutting mechanism. Functions of lathe Machine. The major parts of lathe machine are given as under: 1. Find out the parts and read about the functionality. Among other things, it can be used to cut, sand and turn workpieces. Cross-slide handwheel. tumble reverse. Lathe machine is also known as “ Center Lathe ” because of two centers between which the job can be held and rotated. The part of the lathe on the carriage that allows for angular adjustment of the cutting tool. • Chuck: allows the mounting of difficult workpieces that are not round, square or triangular. The bed of Lathe acts as the base on which the different fixed and operations parts of the Lathe are mounted. Lathe machine is a machine that holds the workpiece on a chuck and tool on a toolpost, the lathe machine rotates the workpiece about an axis to perform different operations such as turning, facing, chamfering, thread cutting, knurling, drilling, and more with tools that are applied to the workpiece to design an object with symmetry about that axis. carriage is a part of lathe which means to be support cutting tool to give feed to cutting tool and control cutting action. Bed; Headstock; Spindle; Tailstock; Carriage. Bed. Now understand bit about all these parts. The thread chasing dial works off the leadscrew and is used as a tracking device. It is used to get the required shape and size of the job. Saddle; Apron ; Cross-slide; Compound rest; Compound slide; Tool post; Feed mechanism; Leadscrew; Feed rod; Thread cutting mechanism; Bed. Lathe Machine Parts: Bed:. Bed 2. lathe bed. Main Parts of a LATHE 1. e) Compound slide. Previously I posted an article about the different parts of a lathe machine. The lathe bed is a mounting and aligning surface for the other machine components. Controls on the side of the head stock allow selection of any one of many speeds, which are arranged in logical geometric progression. These machines have a milling column rising up above the lathe bed, and they utilize the carriage and topslide as the X and Y axes for the milling column. If someone wants to start working in manufacturing industries, they must have to know how to operate a lathe machine. Generating changewheel charts. The mechanism of the carriage is being driven by the feedscrew and also the shaft of the machine itself. Principle parts of a lathe 7 6. Tailstock 10 9. Viewed from the operating position in front of the machine, the headstock is mounted on the left end of the bed and the tailstock on the right. The main function of the headstock is to transmit power... Tailstock:. Main Parts of a LATHE Lathe – Turning Machine 21. These guideways are made with precision to ensure the accurate alignment of other parts. Types of lathe 5 4. All are mounted on the machine in which headstock and tailstock are mounted in the longitudinal direction of machine with gear selector, rpm selector, feed selector in the former and barrel in the later one. The bed of a lathe machine is the base on which all other parts of lathe are mounted. Parts of Lathe Machine and there Functions Previously I posted an article about the different part of Lathe Machine. countershafts. The dial tells you when to engage the half nut lever so the tool follows the same thread groove every time.
