Tool, machine tool, and workpiece machining method

Abstract

A tool (20) has a machine-side machine connection (21) for connecting the tool to a machine tool (1) for driving the tool in rotation (27) about a rotation axis (29) and for advancing (26) the tool relative to a workpiece, a workpiece-side tool head (22) having one or more cutting edges (25) for machining a workpiece, wherein the diameter (D) of the tool head is greater than 20 mm and wherein the cutting edges (25) of the tool (20) are arranged such that they travel over an area perpendicular to the rotation axis (29), a vibration unit (23) which is designed to set the tool head into rotary vibration (28) about the rotation axis (29), and a power receiving means (24) for wirelessly receiving supplied energy and for supplying electrical energy to the vibration unit (23).
