Abstract

L'invention porte sur un affûteur universel d'outils comportant une meule (14) et un système de serrage universel (18) pouvant bloquer fermement l'outil dans un grand nombres de relations spatiales par rapport à la meule, et comportant deux supports incurvés (20, 22) présentant chacun un axe de rotation. Lesdits supports, interconnectés mécaniquement, peuvent se déplacer autour de leurs axes de rotation parallèles respectifs, de manière telle que leur rotation en sens opposé provoque un déplacement non rotatif de l'outil par rapport à la meule.
