ENGINE LATHE
1. The engine lathe is the most commonly used machine-tool. It is used for great variety of metal operations, such as turning, drilling, screwcutting and many others.
2. The principal units of the lathe are the bed, the headstock, the tailstock and the carriage with the apron.
3. The bed is the base of any machine-tool and it is made of grey iron casting on which the saddle and the tailstock slide along special guideways. The headstock is also located and bolted on the bed.
4. The headstock contains the spindle and the speed gearbox. The spindle is the part of the machine to which power is applied to rotate the work. The changing of the spindle speed is effected by levers.
5. The tailstock consists of a casting fitted to the bed. The function of the tailstock is to support one end of the work turned between centres and to mount the tools.
6. The carriage of the lathe, which carries the tool, is made up of two principal parts: the saddle and the apron. The saddle travels along the guideways of the bed. The apron represents the front wall of the carriage. On the front of the apron are mounted the handles and levers by which the actions of the tool are controlled.
