Embodiment Construction

[0090] In FIG. 1 , a device according to the invention is shown very diagrammatically, indicated in its entirety by the reference numeral 10 .

[0091] The device 10 according to the invention is a lathe which is additionally equipped with an actuator 30 for fast piezo-controlled movements of the tool 32 relative to the workpiece 16 . The device 10 includes a main shaft 12 which can be driven to rotate about its main shaft axis 25 as indicated by arrow 28 . Mounted on the spindle 12 is a gripper 14 in the form of a chuck adapted to grip a workpiece 16 . Along a guide extending in the z-direction (parallel to the spindle axis 25 ), a drive 20 is provided on the bed 13 of the device 10 , by means of which the tool carrier 18 can be moved in the z-direction, as indicated by the double arrow 26 . The tool carrier 18 is provided with a drive 22 by means of which the tool carrier 24 can be moved in the vertical direction (y-direction), as indicated by the double arrow 27 . The too...

Abstract

The invention relates to a device and a method for the production of microstructures, comprising: a spindle driven in rotation about a spindle axis, on which a housing for clamping a workpiece is provided; and an actuator (30), which has a rapid drive (36), in particular a piezo-drive for generation of a rapid movement of a tool (32) in a direction essentially perpendicular to the workpiece surface, thereby the actuator (30) may be positioned by means of a further drive (24) for generation of a linear movement in a first direction along a workpiece surface for machining (24). The rapid drive (36) is coupled to the tool (32) by means of a guide device (38) which permits an adjustment of the tool (32) in the axial direction of the rapid drive (36) against a return force and which presents a high rigidity in a plane perpendicular thereto. The applied control technology permits a precise and reproducible production of microstructures using the dynamic system properties.

Description

technical field [0001] The invention relates to a device for forming microstructures by means of a spindle adapted to be driven in rotation about its longitudinal axis and provided with a clamp for clamping a workpiece, the device having an actuator provided with a fast drive, The fast drive is adapted to rapidly move the tool in a direction generally perpendicular to the surface of the workpiece, the actuator being positionable along the surface of the workpiece for operation with an additional drive adapted to produce a linear feed motion in a first direction. [0002] The invention also relates to an actuator suitable for such a device. [0003] Finally, the invention relates to a method for forming a microstructured surface on a workpiece rotatable by a spindle using a tool which can be driven by an actuator and which can be positioned along the workpiece by means of the drive in a linear direction, It is also movable towards the surface of the workpiece by the actuator i...
