12. Taper Turning It is the process in which a conical shape is produced on the work piece. During taper turning the feed is set at an angle to the work piece. 13. Threading The process of making threads on a cylindrical job is called threading

Types of Lathe Machine Lathe machine are generally divided into three types. 1. Engine lathe 2. Turret lathe 3. Special purpose lathe 1.Speed Lathe/ Wood Lathe Remember the Baseball bat, wooden bowl? These are some of the products which can be easily made on wooden lathes or speed lathes. As name suggest, there is a high-speed spindle which can be operate in 3 to 4 varying speeds, near 1000 to 2100 rpm, by shifting the position of the drive belts on the pulley system 2. ENGINE LATHE

Do you want to do operations like turning, drilling, boring, reaming, knurling etc. on a metal? (in short metal machining) Then have a glance on this. It is all started during the 19th and 20th century when the Engine lathes were considers as the ‘KING’ of all machines. It was one of the most common machines set up in every blacksmith shop. The usage of word “engine” is little confusing here. During its early days it was operated on the steam engines, as steam engines were the major invention and power source during the industrial revolution, and with the advancement of time it shifted its power source to the motors 3. TOOL–ROOM LATHE What if I want make precision tools and products?

Some products like metal die, precision tools, jigs and fixture require more precision and accuracy to work; in that case tool room lathe machines are used. Unlike engine lathes, these are much more precise and accurate. . 4. CAPSTAN AND TURRET LATHE What if someone wants to go for a mass production? Because mass production produce work piece in large quantities with duplicate products, which by nature known as interchangeability, reduces error, saves time. All this can be done by using capstan and turret types of lathe machine. 5. SPECIAL PURPOSE LATHE These lathes are constructed for special product making which cannot be performed on the standard lathes. As the name suggest, these lathes are used for special purpose such as heavy- duty production of identical parts. Some example of special lathes includes Automatic lathes, Crankshaft lathes, Vertical lathes, Wheel lathes, Multi spindle lathes, Production lathes, Bench type jewelers’ lathes etc. (i) Wheel Lathes

These are very large in size and made for turning solid wheels and tired wheel, worn out treads of locomotive wheels, roadways wheels etc. into a proper required profile by removing spots, shelling, unwanted shapes. (ii) Bench Type Jewelers Lathes These are the miniature of standard lathes which are designed for the machining of the small parts with greater precision. It contains collet type chuck, feed screw, precise manual cross feed etc. Since the controls and feeds are calibrated in smaller increment which result in better precision of the work piece.

    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.
