LATHE

Introduction:

    Several metal cutting operations are carried out to produce a required shape and size. The metal cutting operations may be carried out either manually by using hand tools such as chisels, files, saw, etc, or using metal cutting machines. When machines perform the metal cutting operation by the cutting tool mounted on them, they are called “machine tools”. A machine tool may be defined as a power driven machine which accomplishes the cutting or matching operation on it. The fundamental machines tools that are used for most of the machining processes are lathe, drilling, tapping, planning, milling, and grinding machines.

LATHE:

  

A lathe is a machine tool employed generally to produce circular objects. It is said to be the mother of all machine tools, since it is so versatile, that all the machining operations which are performed on other machine tools like, drilling, grinding, shaping, milling, etc, can be performed on it.

Various types of lathes are being used in practice to perform variety of machining operations. Depending on their characteristics functions, lathes are classified as:

1. Engine Lathe

2. Speed Lathe

3. Turret Lathe

4. Capstun Lathe

5. Automatic Lathe

6. Computer Numerically Controlled (CNC) Lathe
