Abstract
A tool head for the precision cutting of a surface of a rotating workpiece has a cutting tool which is movable in opposition to the force of a restoring spring from an initial position into an operating position with respect to the workpiece via an actuating drive. The actuating drive is formed by a translatorily movable driving element and a transfer element which converts the driving movement into an adjusting movement. The driving element used for adjusting the cutting tool from the initial position to a machining position is formed by an expansion bar actuated by magnetostrictive principles.
