Abstract (en)

A dressing method and apparatus is provided for dressing a lens grinding stone. A dressing disk (60) is constructed by uniting at least one rough dressing stone (61) with a finish-dressing stone (62). The rough dressing stone (61) is rougher than the lens grinding stone to be dressed. The finish-dressing stone (62) is substantially as fine as the lens grinding stone or is finer than the lens grinding stone. In order to dress the lens grinding stone, rough processing is first carried out with the rough dressing stone (61), and then finishing dressing is carried out with the finish-dressing stone (62). <IMAGE>
