The special nature of the material has long inhibited the technological development of the sector, which relied rather on a "craft" approach based solely on experience. However, the evolution of design and the latest trends in the use of marble for interior architecture are pursuing increasingly complex geometries, for which the use of a CNC machine is essential.
There are also some specific problems associated with working with marble. In order to cut marble and prevent the tool from overheating and breaking, it is necessary to use a cooling liquid, usually water. This leads to very strong corrosion; for this reason, the machines are treated with special paints to preserve their integrity.
