Abstract (en)
[origin: WO2004004974A1] The invention relates to a method and a device for the hydro-erosive rounding of an edge of a component, in particular, an edge in a channel of a high-pressure resistant component, whereby a fluid charged with abrasive bodies is run along the edge for rounding and the flow speed in the vicinity of the edge for rounding is increased by means of a body arranged in the fluid flow path. According to the invention, with relation to the method, the flow speed of the fluid (6) is increasingly raised along the course of the body (7) until the edge (5) for rounding is reached by means of the geometry of the body (7) and, with relation to the device, the cross-sectional area of the flow channel (10) continuously declines in the direction of flow (S) of the fluid (6) along the length of the body (7) at least as far as the edge (5).
