Abstract
A boring head includes a housing having a first end configured to be coupled to a machine tool and a second end positioned opposite from the first end with the housing defining a central passageway. The boring head also includes a diameter adjustment mechanism comprising a sliding holder received by the housing and movable relative to the housing with the sliding holder configured to be coupled to a cutting insert and a balancing mechanism having a balancing mass. The balancing mechanism is configured to move the balancing mass when the sliding holder is moved. The balancing mass is aligned with the sliding holder in a direction extending about perpendicular to a longitudinal axis of the housing.

A boring head comprising:
- a housing having a first end configured to be coupled to a machine tool and a second end positioned opposite from the first end, the housing defining a central passageway;
- a diameter adjustment mechanism comprising a sliding holder received by the housing and movable relative to the housing, the sliding holder configured to be coupled to a cutting insert;
- a balancing mechanism comprising a balancing mass, the balancing mechanism is configured to move the balancing mass when the sliding holder is moved, the balancing mass is aligned with the sliding holder in a direction extending about perpendicular to a longitudinal axis of the housing.
A boring head comprising:
- a housing having a first end configured to be coupled to a machine tool and a second end positioned opposite from the first end, the housing defining a central passageway;
- a diameter adjustment mechanism comprising:
- a sliding holder received by the housing and movable relative to the housing, the sliding holder configured to be coupled to a cutting insert;
- a sliding pin received within the passageway of the housing, the sliding pin having a main body, an angled portion extending from the main body, and a translation member having a threaded surface;
- a dial received by the housing and rotatable relative to the housing, the dial having a threaded surface that cooperates with the threaded surface of the translation member, wherein rotation of the dial causes movement of the sliding pin.
A method of automatically balancing a boring head having a housing, a sliding pin, and a diameter adjustment mechanism comprising a sliding holder movable relative to the housing and configured to be coupled to a cutting insert, the method comprising:
- connecting a balancing mass to the sliding holder via a lever that transmits radial movement of the sliding holder to the balancing mass;
- and
- aligning the balancing mass with the sliding holder in a direction extending about perpendicular to a longitudinal axis of the housing.
