Abstract
A workpiece is cut by a cutting tool that is attached to a cylindrical support body vibrated by at least two piezoelectric drive elements. The efficiency of the mechanical vibration is improved by attaching the piezoelectric drive elements to a cylindrical body portion (7,7.1,7.2) of the tool support body (2) and by providing the support body with a plurality of necked-down end sections. At least the cylindrical body portion (7,7.1,7.2) is a cylinder with a substantially circular cross-section or with a circular cross-section to provide a constant or a substantially constant bending rigidity of the cylindrical tool support body.
