Patent AT-E400402-T1: [Translated] DEVICE AND METHOD FOR GENERATING MICROSTRUCTURES

The device for producing microstructures has a rotating driven spindle (12) and a holder for clamping a workpiece (16). A fast drive is coupled to a tool (32) over a guidance arrangement, which permits adjustment of the tool in an axial direction of the fast drive against a return force. The drive has high rigidity in the plane perpendicular to the drive direction. An independent claim is made for an actuator (30) for moving the tool of a turning machine (10) to produce a micro-structured surface in a workpiece, especially using a piezoelectric drive.
