Abstract
A tool 1 comprises a single rib dressing roll 5 and two semi-rib dressing rolls 10, 11 separated by spacers 13. The two flanks 31, 33 of a first lead 32 of a grinding worm 30 are dressed by the two flanks 6, 7 of the single rib dressing roll, and the two flanks 35, 38 of a second lead 36 are dressed by the two flanks 14, 16 of the semi-rib dressing rolls. Fast dressing with a long service life and a short dressing stroke are thus obtained.
