#CMT# #/CMT# 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. #CMT# : #/CMT# 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. #CMT#USE : #/CMT# Microstructure machining tool, especially for producing templates for poly-elipsoid headlamp lenses, that are to be produced using hot-pressing. #CMT#ADVANTAGE : #/CMT# Can be used with hard metals such as cast gray iron and can be used to machine non-rotationally symmetric workpieces. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a schematic view of an inventive device. 10 : turning machine 12 : driven spindle 16 : workpiece 32 : tool 30 : actuator. |
