Counterbalancing system for movable rotating machine tool parts incorporates additional counterweights to eliminate wobble of drive shaft

摘要

A machine tool has one or more tools (2) adjustably mounted on the axis of rotation (1) and a weight (3a) on an axis (1a) to balance the linear moments and a further weight (3b) on an axis (1b) to counter the wobble moment introduced to accurately balance the entire rotational forces.
