摘要
A water-jet operating head for cutting materials by a high pressure hydro-abrasive jet includes a main portion which is to be carried by an operating machine movably along one or more axes and a focusing nozzle for ejecting the high pressure hydro-abrasive jet, carried by a support removably connected to the main portion of the head. This support also carries a primary nozzle with an orifice having a predetermined diameter arranged upstream of the focusing nozzle. The high pressure water jet is added with an abrasive agent which is fed through at least one connecting element at a mixing chamber interposed between the primary nozzle and the focusing nozzle. The connecting element is associated to the main portion of the head and the nozzle-carrying support is adapted to be slidably received within a cylindrical cavity of a main support forming part of the main portion of the head.
