Abstract: The invention relates to a brush comprising a support made of a plastically deformable plastic material for disposing bristle clusters (13) thereon, the support having a plurality of cluster holes (14) each serving to accommodate one bristle cluster (13), the bristle clusters (13) each being fixed in a cluster hole (14) by means of a clip (16), and the clips (16) being provided with discontinuous structural elements at least in the area of clip projections (23, 24) on at least one longitudinal side (22) disposed essentially parallel to a cluster hole axis, wherein the structural elements are disposed at a distance to the longitudinal edges of the clip (16).

Abstract: A brush including a support made of bamboo material having a plurality of cluster holes each accommodating one bristle cluster fixed in a cluster hole by a clip having a length l greater than the diameter D of the cluster hole to form clip projections on both longitudinal ends. The clips have at least two wedges on at least one side disposed one above the other in the direction of the vertical axis and widening upward, the upper ends of the wedges forming catch shoulders extending in the longitudinal direction of the clip, wherein a press-in end of the clip having a reduced width is formed at a lower end of the lower wedge.

Abstract: In order to achieve a reduction in wear of the wire guide rollers, apart from an improvement in the cutting speed and an improvement in current conduction, a wire electrode for spark erosion cutting of metals etc., comprising either a homogenous center (1) made of a metal or of a metal alloy, or a composite center, is provided with a sheath coating (2) whose surface is structured, wherein the indentations (3) created by the structure, are filled by a filler (4) made of an easily vapourable metal or of a metal alloy, so as to achieve a surface with little peak-to-valley height, i.e. with little surface roughness.

Abstract: A wire electrode for spark erosion cutting of metals, electrically-conducting ceramics etc., comprising either a homogenous centre (1) made of a metal or of a metal alloy, or a composite centre made from a steel core with a coating of copper or copper alloy, wherein the wire electrode comprises at least two sheath coatings made of zinc alloys, with said coatings wearing during erosion. In order to increase performance during high-speed cutting, such a wire electrode comprises an inner sheath coating (2) predominantly comprising &bgr;-brass, and an outer sheath coating (3) predominantly comprising &ggr;-brass, wherein the fraction of &bgr;/&bgr;′-phase or &ggr;-phase in the two sheath coatings is at least 60%. The ratio of the coating thickness of &bgr;-brass to &ggr;-brass is between 0.3 and 7. The sum of the thicknesses of both sheath coatings in relation to the external diameter of the electrode is between 0.1 and 0.3.
