ABSTRACT:
The system of modular elements comprises a plurality of disc elements (11, 12 . . . ) with diamond outer rings (11a, 12a . . . ) for assembling on a single drive spindle with a spacing approximately equal to their thickness; mechanical fragmenting means (19, 20, 21, 22 . . . ) being provided in the spaces between the disc elements to operate essentially by impact, in contrast to the abrasive action of the diamond outer ring of the said disc elements; which disc elements have different diameters forming a broken line that corresponds substantially to the outline of the profile or shaping to be produced on marble, stone or the like; the arrangement being such that the disc elements (11, 12 . . . ) cut grooves by diamond abrasion and the mechanical fragmenting means (19, 20, 21, 22 . . . ) shatter the parts projecting from the grooves with an action of fragmentation by impact and by brittle fracture.
