Fine and coarse structured surface machining of workpieces, particularly printing rolls uses two different machining systems to produce fine and coarser details

摘要

Finely detailed areas and/or coarsely detailed areas of the workpiece (2) are marked out on the workpiece. A laser beam from a controlled laser source (4,5) is then used to produce finely detailed structures in the appropriate areas and the coarser details are created by a separate material removal unit (8). Independent claims are made for (1) equipment for machining workpieces which has a controllable laser source (4,5) producing a beam (6) for machining fine details and a controlled coarse material removal unit (8); (2) a printing plate whose layer (3) to be structured comprises a carrier layer, a first material layer with material properties suitable for producing coarsely detailed structures using a laser and/or a mechanical material removal tool and a second material layer whose properties are more suited to laser machining of fine structures.
