Abstract
The present invention shows an apparatus for a chamfer machining of a toothed workpiece comprising a workpiece spindle having a workpiece holder rotatably supported about an axis of rotation for holding the workpiece, a tool spindle having a tool holder rotatably supported about an axis of rotation for holding a finger mill, wherein the tool spindle is travelable relative to the workpiece holder via at least one linear axis of the apparatus, and a control having a machining function that rotates the workpiece held in the workpiece holder by controlling the workpiece spindle for the chamfer machining of a toothed workpiece while a finger mill held in the tool holder engages at the edge to be machined. It is characterized in that the machining function varies the rotational speed of the workpiece during the chamfer machining.
