Summary: Enlarging and finishing holes.

Boring machines are machine tools designed to enlarge or finish existing holes with precision. Unlike drilling, which creates the initial hole, boring precisely controls the hole's diameter, roundness, and straightness.

Function: Boring machines are used to:

    * Enlarge holes to a specific size with tight tolerances.

    * Improve the roundness and straightness of holes.

    * Create internal tapers or other shapes within a hole.

Mechanism: They use a single-point cutting tool mounted on a boring bar, which is rotated and fed into the workpiece.

    Types: Boring machines vary in size and configuration, including:

    Horizontal boring mills: Versatile machines capable of machining large and complex parts.

  Vertical boring mills: Used for machining large, heavy workpieces that are difficult to hold horizontally.

    Jig borers: High-precision machines for accurately locating and boring holes.

   Boring machines are essential for producing accurate holes in engines, machinery, and other applications where precise internal dimensions are critical.
