Abstract: The invention relates to implement the sealing, porosity and sweeping functions, combined. For this purpose, the present invention proposes to confine the waste and to suction the waste at the ejection head by means of a sufficiently flexible connection, such as to remain in contact with the machining area. According to an embodiment, a portable machining machine (1) operated by a pressurized jet (112) includes a waste recovery system (5), an injection head (11) which is provided with a nozzle (111) having an axis (A1) that is substantially perpendicular to the surface to be machined (4a) and which is driven by a digitally controlled two-axle guide system, the ejection head (11) being extended by an enclosure (12) to the surface area to be machined (4a). In addition, the enclosure (12) comprises a tubular portion (121) consisting of two walls (12a, 12b) which slide coaxially along the axis (A1) and a double-pivot articulation device (123).
