The invention relates to a machine, for the working of the walls which define the cavity of a continuous casting mould, with machine-cutting and/or polishing tools (12). The machine comprises a machine stand (1), with an arm (6), for mounting the tool (12), which may be introduced into the cavity and a table (8), for fixing the mould (7) and devices for generating an N.C. controlled relative displacement between the tools (12) and the walls. A rotatory movement of the tools (12) about axes (13), which are arranged essentially transverse to the longitudinal axis of the arm (6), is disclosed, which, in combination with a swinging movement of the arm (6) about the longitudinal axis thereof, permits a high precision in the working, even in the case of a cavity with a taper varying in the longitudinal direction and/or along the circumference of a section thereof, or in the case of a cavity with a particular corner configuration.
Pour le traitement de parois délimitant la soufflure d'une coquille de coulage continu (7), on fait intervenir selon l'invention une machine comportant des outils d'usinage et/ou de polissage (12). Ladite machine est composée d'un montant de machine (1) comportant un bras (6) destiné à recevoir les outils (12), pouvant être introduit dans la soufflure, d'une table (8) destinée au montage de la coquille (7), ainsi que de dispositifs destinés à produire un mouvement relatif à commande numérique entre les outils (12) et les parois. Pour atteindre un degré de précision élevé lors de l'usinage, même lorsque la conicité varie dans le sens longitudinal et/ou périphérique d'une section transversale de la soufflure, ou lorsque la soufflure présente des configurations de coins spéciales, on combine un mouvement de rotation des outils (12) autour d'axes (13) essentiellement disposés perpendiculairement à l'axe longitudinal (4) du bras (6), avec un mouvement d'articulation du bras (6) autour de son axe longitudinal (4).
