Autobalancing system for boring tool and boring tool incorporating same

摘要

A boring head (10) having a movement transmission mechanism for selectively moving a cutting insert (20) a desired amount. The movement transmission mechanism includes a rotatable member selectively radially displacing the cutting insert the desired amount in a first direction and a primary member selectively radially displacing a balancing mass (50) in a second direction opposite the first direction while also axially displacing the balancing mass. The displacement of the balancing mass in the second direction effectively counters the displacement of the cutting insert in the first direction such that rotational balance of the boring head is automatically maintained.
