  • Patent number: 5690779
    Abstract: The invention relates to a method and an apparatus for the production of a plate with depressions or apertures which is coated on at least one side. Plates of this kind are employed, for example, as passage-containing plates in hydraulic blocks for ABS/ASR/VDC systems, the depressions or apertures serving as passages or holes and the coating being a seal. In this invention the depressions or apertures are formed in an uncoated plate and then the plate is coated. As a result, the life of the machining tools is extended, the machining tolerances become smaller and the rate of machining can be increased.
