Can you develop all the value-added products from the same type of lathe? The answer is no, not possible. So, there have been many types of lathe machine to make unprecedented products. Working Principle of Lathe Machine A lathe is a machine tool which is used to rotate a work piece to perform various operations such as turning, facing, knurling, grooving etc., with the help of tools that are applied to the work piece. The function of lathe is to remove metal from a piece of work to give it a desired shape and size. In a lathe machine, the work piece is rotate against the tool. The tool is used to remove material fro the work piece. The direction of motion of tool is called feed. Main Parts of Lathe Machine

The various main parts of lathe machine are 1. Headstock It is present at the left-hand side of the lathe. It holds the gear train, main spindle, chuck, gear speed control levers and feed controllers. It is aligned with the tailstock. The head stock is made up of cast iron. (i) Chuck It is that part of lathe machine which is used to hold the work piece. It is attached to the main spindle of the headstock. It rotates with the spindle and also rotates the work piece. In the lathe machine we generally use three jaw or four jaw check. The three jaw of the three jaw chuck is made to move simultaneously but the jaws of the four jaw chuck moves independently.

Tailstock It is present at right hand side of the lathe. It is used to provide supports to the work piece. It supports the work piece from one end i.e. right end. 3. Bed It is the main part of the lathe. All the parts of the lathe is bolted on the bed. It comprises of headstock, tailstock, carriage guide ways and other parts. It is made of cast iron. Guide ways Guide ways are present on the bed. As its name indicates it is used to guide the tail stock and carriage. The tailstock and carriage, slides over the guide ways. It is an inverted V. 4. Carriage The carriage is present in between the headstock and tailstock. It carries apron, saddle, compound rest, cross slide and tool post. (i) Tool Post: It is used to hold the tool. It has T-slot for holding the tool. Tool post is bolted on the carriage. (ii) Compound Rest: It is used to set the tool at desired angle for taper turning and other operations. (iii) Cross Slide: The cross slide is used to move the tool perpendicular to the axis of the lathe. (iv) Saddle: The top portion of the carriage is called saddle. Cross slide is mounted on the saddle.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
