Definition of Lathe Machine
A lathe machine is defined as a machine tool that holds a workpiece in a rotating chuck while a stationary cutting tool removes material to shape the workpiece. Lathes are used for a variety of operations such as turning, facing, threading, knurling, and drilling, allowing for the creation of symmetrical objects around an axis.
Parts of a Lathe Machine
Understanding the main components of a lathe machine is vital for effective operation and maintenance. Here are the key parts:
- Bed: The heavy base that supports all other parts.
- Headstock: Contains the motor and the spindle to hold the workpiece.
- Tailstock: Provides support for the free end of the workpiece.
- Carriage: Holds the tool post and allows for linear movement.
- Tool Post: Secures the cutting tool in place.
- Chuck: A device that holds the workpiece securely.
- Feed Mechanism: Controls the movement of the carriage and tool.
- Apron: Located on the front of the carriage, it houses the controls.
