Abstract
Full profile dressing roll () for dressing multi-start grinding worms for the generation grinding of small-module gears, comprising a groove-shaped axial section profile of the outer envelope surface (), covered with hard material grains, and profile-cut hard-material profile combs () embedded in this envelope surface and having a multi-ribbed rack tooth system profile, the profile of which touches the outer envelope surface () of the dressing roll () only in sections of the axial section profile of the dressing roll () which do not participate in the generation of the grinding worm flanks. As a result, the profile sections, highly stressed during the dressing, at the crest and root of the profile grooves () are protected from high wear and premature grain loss and the service life of the dressing roll is effectively increased without the inhomogeneity of the flank surface of the dressing roll () being disturbed by the profile combs ().
