Abstract (en)
[origin: WO2021058142A1] The invention relates to a dressing tool which has profiled elements (11.1, 11.2, 12.1, 12.2, 12.3, 12.4) which are arranged coaxially with one another and which are each provided with a profile form, which is tapered or the like in its axial cross-section and has working surfaces (13, 14) which are provided with hard-material particles. The profiled elements (11.1, 11.2, 12.1, 12.2, 12.3, 12.4) are delimited at their outer circumference by at least one generated surface (23, 24). The dressing tool (10) comprises six profiled elements (11.1, 11.2, 12.1, 12.2, 12.3, 12.4) arranged coaxially with one another and a one-part or two-part metallic main body (19) for the entire dressing tool (10) or for a particular generated surface (23, 24). The profile forms with the hard-material particles of the profiled elements (11.1, 11.2, 12.1, 12.2, 12.3, 12.4) are produced here by a negative process with a casting compound (15) applied to the particular main body (19). This dressing tool can thus be used for a profiling of grinding worms extremely productively and precisely and also such that they can be corrected.
