Answer :

A center lathe is a machine tool that rotates a workpiece about an axis of rotation to perform various operations, such as cutting, sanding, knurling, drilling, or deformation with tools that are applied to the workpiece. It's a fundamental machine used in mechanical engineering and manufacturing industries.

The main components of a center lathe include:

  1. Headstock: The headstock is located on the left side of the lathe and contains the motor which generates power to rotate the spindle. It is responsible for holding the workpiece in place and driving its rotation.

  2. Tailstock: Situated on the right end of the lathe, the tailstock supports the other end of the workpiece. It can be adjusted along the length of the bed for various lengths of workpieces and operations.

  3. Apron: The apron is part of the carriage and contains controls for movement of the carriage along the bed of the lathe. It facilitates the automatic movement of tools.

The term Arbor is not a component of a center lathe. An arbor is typically a shaft or spindle which may hold tools like mills or saws, used in combination with other machine tools such as milling machines.

Thus, among the options provided, the term 'Arbor' is not a part of a center lathe.
