Abstract: The invention relates to a holding system (1) for holding substrates (12) for use in a surface processing system having a covering area (20), comprising a plurality of fixing elements (2), a body (24) arranged within the covering area (20) for receiving the fixing elements (2), and a positioning element (26) for adjusting the covering and a machining area (20, 22), wherein a plurality of substrates (12) can be fixed by the fixing elements (2) and processed within the machining area (22).

Abstract: The present invention relates to a method for producing coated substrate bodies, wherein a plurality of substrate bodies comprising surfaces to be coated are provided with a colored coating surface, the method comprising following steps: providing the substrate bodies to be coated in the interior of a vacuum coating chamber, depositing a coating on a surface of the substrate bodies to be coated, the deposition of the coating involving the deposition of a metallic layer comprising at least two different metals, forming a colored oxide layer exhibiting a colored surface by anodic oxidation of the metallic layer, wherein: the anodic oxidation takes place in an alkaline electrolyte bath with the coated substrate bodies connected as anodes.

Abstract: The invention relates to a deep-hole drill, comprising a first coating extending over the effective length of the guide section and a second coating that is applied to the tip of the drill in the cutting region, the region of which extends over an axial length that, at a maximum, corresponds to double the nominal diameter of the drill. In such a way, when the bore tip is worn by use, said tip can be recoated after sharpening without the nominal diameter of the drill tip substantially increasing, in particular even after being sharpened several times.
