A lathe machine is a fundamental piece of industrial machining equipment used to shape materials such as metal, wood, or plastic. It works by rotating a workpiece around a fixed axis while a cutting tool removes material to create symmetrical shapes.
The basic principle of a turning machine is simple: the material spins, and the cutting tool remains stationary or moves along specific paths. This process is known as turning. Lathes are widely used in precision engineering, automotive manufacturing, aerospace components production, and tool making.
Historically, early versions of lathe machines appeared thousands of years ago in manual form. Over time, mechanical improvements introduced engine lathes, and modern technology led to the development of CNC lathe machines (Computer Numerical Control). Today, CNC turning centers use automated programming to produce complex components with high accuracy.
Common types of lathe machines include:
-
Engine lathe
