Abstract (en)

[origin: WO2020074296A1] The invention relates to a method for machining the edge of the radial bores (21) in the connectors (2) for the branch of the injection nozzles to the axial chamber (11) of a common fuel line (100) of an injection system of an internal combustion engine, wherein, according to the method, the mouth of the radial bores (21) into the chamber (11) of the common fuel line is deburred. A connecting rim (3) in the form of a surface of revolution (3S) about the axis (ZZ) of the bore (21), said connecting rim (3) grinding down the edge (22) of the mouth of the radial bores (21) into the axial chamber (11) that protrudes from the surface (11S) of the axial chamber (11) and that (21S) of the radial bores (21), is produced.
