ABSTRACT:
To optimize the results of rounding and therefore to optimize the high pressure resistance of the component, it is firstly proposed that prior to the machining step of hydro-erosive rounding, the edge (5) and the surfaces (4, 6) of the high pressure-resistant component (1) which adjoin the edge (5) are each placed under compressive stresses in the region of their surface by means of a grinding and/or honing process. Also with regard to the method, and with regard to an apparatus for the hydro-erosive rounding, it is proposed that a closure element (9) is inserted into the continuing first bore (2), downstream of the second bore (3), which branches off from the first bore, as seen in the main direction of flow (S) of the liquid (8) mixed with abrasives (7), in order to divert the liquid (8) mixed with abrasives (7) from the first bore (2) into the second bore (3).
