The invention relates to a work station for electrochemically machining a workpiece, having a number of recesses, including a base structure; a module which is fastened to the base structure and is configured to electrochemically machine the workpiece. A workpiece holder is fastened to the base structure. The workpiece holder is movable relative to the base structure along a feed axis which is parallel to the axis of rotation of the module. The module includes an electrode carrier arrangement, which is coupled to the module base body so the electrode carrier arrangement can be rotated together with the module base body about the axis of rotation of the module. The electrode carrier arrangement has a carrier frame and an electrode frame, where at least one electrode is detachably fastened to the electrode frame.

The invention relates to a device and a corresponding method for manufacturing brush seals with obliquely positioned bristles. The method comprises the following steps: As the first step, a metal filament or wire () comprising a material for bristles is wound over two wire cores () disposed at a distance from and running parallel to one another, to form a tightly packed metal filament or wire package (). As the next step, the metal filament or wire package () is fastened to at least one wire core (). Then the region around at least one of the two wire cores () is locally heated. Subsequently, at least one of the two wire cores () is displaced.
