Abstract (en)
The present invention concerns an alternative machine for cutting stone blocks with a laminated diamond tool, in which the cutting is done vertically during the descendent stroke, the inverse stroke movement being passive for the cutting. Besides, the support structure of the diamond blades is compensated statically by another structure having the same mass which can be passive or active to cut if it bears or not a diamond tool and which describes a parallel movement to the first one but with a phase difference of half cycle. The present machine is useful to cut ornamental stones.
