The invention relates to a method and a device for machining workpieces (6) comprising an annular-shaped section that is to be provided with a split bore (10). Said device comprises: a fracture-splitting device for fracture- splitting the annular-shaped workpiece section and for creating fracture-split workpiece parts (6.2, 6.4) corresponding with one another with a split bore (10); an applicator device for a plain-bearing material for applying at least one closed annular plain-bearing layer (12) to the inner periphery of the split bore (10) of the fracture-split workpiece (6.2, 6.4); and fracture- splitting device for the plain-bearing layer (2; 8, 8.2, 18, 20, 22, 24) for fracture-splitting the closed annular plain-bearing layer (12) of the previously fracture-split workpiece (6.2, 6.4).
L'invention concerne un procédé et un dispositif d'usinage de pièces (6) ayant une section annulaire dotée d'un orifice divisé (10). Ce dispositif comprend un dispositif de fragmentation destiné à fragmenter la section annulaire de la pièce et de produire des éléments de pièce (6.2, 6.4) fragmentés correspondants avec l'orifice divisé (10). Le dispositif comprend également un dispositif d'application de matière de palier lisse permettant d'appliquer au moins une couche de matériau de palier lisse (12) annulaire fermée sur la circonférence interne de l'orifice divisé (10) de la pièce fragmentée (6.2, 6.4); et un dispositif de fragmentation de couche de matériau de palier lisse (2; 8, 8.2, 18, 20, 22, 24) permettant de fragmenter la couche de matériau de palier lisse fermée (12) de la pièce (6.2, 6.4) préalablement fragmentée.
