ABSTRACT:
A high-speed abrasive liquid jet is directed at the surface of the component (13) with an angle of incidence between 30.degree. and 90.degree.. The jet is moved so as to sweep over the internal surface of the component (13). At least two successive machining passes are made. The speed of sweeping increases from one machining pass to the next. The device (30), mounted so as to move in translation and in rotation inside the adaptor (13), consists of a tube assembly supplied with pressurized liquid onto which a nozzle (33) is fixed.
