The lathe is one of the most important machines is the machine shop. It removes material from a revolving work by using suitably formed cutting tools of hardened, and tempered steel. There are different types of lathes.
The engine lathe is used mostly in tool shops. Because of its ability to perform various kinds
of work it requires a great degree of skill to operate.
Engine lathes vary in size, ranging from the small lathe of only a few inches to one many feet in length. The size of the engine lathe is based upon two measurements – the approximate largest diameter that can be revolved over the way sand the total length of the bed.
The turret lathe is equipped with a turret that is of hexogen shape and isused for holding cutting tools.
The rapid production lathe and the automatic lathe are used for the production of small
The most important parts of the lathe are: bed, carriage, headstock and tailstocks, thread
cutting instruments and feeding mechanism.
The bed consists of two heavy metal sides with V-shaped ways formed upon them.
The carriage is the movable part which slides between the headstock and tailstock.
The headstock consists of the headstock casting which is located on the ways at the left of the operator, the spindle in which the live center is held by the necessary mechanisms for obtaining various spind lespeeds.
The tailstock is a movable casting located opposite the headstock on the ways. It contains the dead center, the adjusting screw and band wheel.
The thread-cutting mechanism includes any gear or mechanism, which transmits the motion
fromthemain spindleto thelead screw.
The feeding mechanism is a series of gears which transmits motion from the headstock or
main spindleto thefeed rod. Themotion isthen transmitted from the feed rod to variousgears.
The two lathe centers are used for supporting the workpiece. The dead center is located in the tailstock and does not revolve.The live center is contained in the spindle and revolves with the workpiece. The dead center is to be always kept well lubricated with oil.
