Abstract (en)
[origin: EP1977867A1] A high pressure fluid jet tool for surface working of slabs or blocks of stone, marble or the like, comprises a support plate (2) with a plurality of nozzles (3) mounted thereto for connection to a high pressure fluid line (4), means for removably anchoring the plate (2) to a spindle (6) that rotates about an axis of rotation (X) substantially perpendicular to the surface to be worked (S). The plurality of nozzles (3) includes at least two separate arrays of nozzles (7, 7') arranged over the plate (2) along respective mutually offset curved lines (8, 8'), so that, as the plate (2) is rotated, the fluid jets (J) interact with the surface to be worked (S) in apparently random paths. A tool holding head is provided for surface working of slabs and blocks of stone, marble, granite, stone and/or cementitious agglomerates.
