Autobalancing system for boring tool and boring tool incorporating same

摘要

A boring head comprises a housing disposed about a central longitudinal axis and a movement transmission mechanism disposed at least one of on or in the housing. The housing includes a first end adapted to be coupled to a machine tool and an opposite second end having a cutting insert movably coupled thereto. The movement transmission mechanism comprises a rotatable member mounted to be rotatable relative to the housing, a balancing mass, and a main shaft disposed in the housing. The main shaft is rotatable about the longitudinal axis and operationally coupled to the ring, the balancing mass, and the cutting insert. Rotation of the rotatable member a predetermined amount causes movement of the cutting insert a corresponding predetermined amount in a first radial direction with respect to the longitudinal axis and movement of the balancing mass a corresponding predetermined amount in a second radial direction opposite the first radial direction.
