Abstract:
1. A method for machining an edge of a high pressure-resistant component, in particular an edge of a bore intersection of a high pressure-resistant component of a fuel injection system, the method comprising the steps of: placing the edge and the surfaces of the high pressure-resistant component which adjoin the edge each under compressive stresses by means of a grinding and/or honing process, and rounding the edge hydro-erosively in one machining step thereby removing a particular depth of material from the surfaces of the component; wherein parameters of the grinding and/or honing process are selected for producing particular compressive stresses at particular depth below the surfaces of the component, and parameters of the hydro-erosive rounding process are selected for the removing of the particular depth of material from the surfaces of the component, such that after the hydro-erosive rounding process removes the particular depth of material from the surfaces of the component compressive stresses of at least 200 N/mm
