FIELD: cutting out different materials by means of supersonic liquid jet. SUBSTANCE: apparatus includes supporting table, movable carriage with nozzle unit and receptacle for technological liquid. In upper portion of receptacle there are two reflectors forming slit widened downwards. In power portion of receptacle coaxially with slit, cone like jet splitter is arranged. Faces of splitter cone are parallel relative to respective sides of reflectors widened downwards. It provides reduced level of acoustic pressure at operation, eliminates splashing and water mist generation. EFFECT: enhanced ecology of method. 2 dwg
