CENTER LATHE
Introduction
Lathe is the oldest tool invented, starting with the Egyptian tree lathe. In Egyptian tree lathe, one end of the rope wound round the work-piece is attached to a flexible branch of a tree, while the other end is pulled by the operator, thus giving rotary motion to the work-piece. It is one of the most fundamental and versatile device, used practically in all the manufacturing shops.
The principal form of surface produced in the lathe is the cylindrical surface. It is achieved by rotating the work-piece, while single-point cutting tool removes the material by traversing in a direction parallel to the axis of rotation.
A large number of variants of lathes are used in manufacturing shops. The variations are
1. Centre lathe(engine lathe)
Bench lathe
2. Tool room lathe
3. Special purpose lathes
Copying lathe
Gap bed lathe
Hollow spindle lathe
4. Capstan and turret lathe
5. Automatic lathe
The centre lathe (commonly used), which derives its name from the way a work-piece is clamped by centre in a lathe, though this is not the only way in which the job is mounted.
The tool room lathe is generally meant for tool making where accuracy is of higher priority. Thus, the machine would have a higher range of speeds and feeds along with greater rigidity with a larger range of accessories and attachments.
The special purpose lathes are developed from the centre lathe to crater to special forms of application, which cannot be handled by the conventional centre lathe.
Capstan and turret lathes are used for very special application as they have high rate of production.
