The lathe is a machine tool which is used for producing components, that are symmetrical about an axis. It can be used for machining cylindrical surfaces both external and internal, and also for the turning of conical surfaces or tapers. An additional feature of the lathe, is its ability to cut screw threads on a surface that has already been machined. The accuracy of the work done on a lathe, depends on the skill and experience of the operator. A lot of time is taken for tool setting, tool changing,etc., with the result that it is unsuitable for production work. It is mainly used in tool rooms and workshops for the making of prototypes, and also for maintenance work.
