Abstract

a. Procédé destiné à compenser les affaissements dus à la sortie de la douille dans les aléseuses à montant mobile. b. Procédé selon lequel la compensation s'effectue en faisant tourner le chariot de l'aléseuse, en particulier en soulevant sélectivement les glissières sur lesquelles coulisse ledit chariot c. Aléseuse comprenant un systeme de compensation selon lequel les glissières du banc sont soumises à une pression qui tend à les soulever différemment l'une par rapport à l'autre, en réalisant ainsi une rotation de l'ensemble de l'aléseuse elle-même, cette compensation de la déformation étant automatique et variable en relation à la sortie de la douille. d. Le procédé et le dispositif sus-indiqués peuvent être employés avec avantage particulier dans les aléseuses à montant mobile.
