The machine uses a high-pressure waterjet directed at the surface, which produces cavities of variable depth. The level of texture depends on the structure and composition of the material being processed, and the process can be used on thicker slabs as well as thin stones, since the structure of the treated material does not suffer any loss of strength from the process, Pellegrini reports.
The working head has a nozzle system with six orifices, and the number of orifices in use can be adjusted as needed depending on the desired texture or the hardness of the material being processed. Additionally, the texture can vary based on the slab feed speed.
