Abstract

La présente invention décrit un procédé et un appareil de traitement d'un outil rotatif long (22) avec tranchant (30). Le procédé comporte un certain nombre d'étapes, consistant à projeter sous pression, à l'aide d'une buse (60), un jet de liquide abrasif contenant des grains abrasifs entraînés; et à amener ledit jet de liquide à heurter le tranchant (30) de l'outil rotatif long (22), pendant une période prédéterminée, de manière à affûter relativement uniformément le tranchant (30). L'appareil (50) comporte un porte-outil rotatif (54) déverrouillable pour l'outil rotatif long (22). Une buse (60) projette sur l'outil un jet de liquide abrasif sous pression. Ladite buse (60) et l'outil rotatif long (22) peuvent se déplacer l'une par rapport à l'autre de sorte que le jet abrasif puisse heurter le tranchant (30) sur toute sa longueur.
