The head (8) with multiple nozzles (2) rotates on an axis passing through it. It can be slid in relation to the work (1), and is adjustable for angle in relation to it, so as to give a water jet variable from the perpendicular position to one at 45 deg. to the latter. The work and head are accommodated in a container (6) closed on all sides, and which has a drain (4) at the bottom containing a filter (7). The drain can lead to the pumping set (3) supplying the water, and the head can be arranged to slide at a constant distance from the work surface. It can work in a Cartesian coordinate system. |
