Abstract

Appareil auxiliaire pour faciliter le réaffûtage de forets hélicoïdaux à l'aide de la surface latérale de la meule, montée sur un axe horizontal, d'une meuleuse, ou d'une rectifieuse d'outillage, munie d'un établi de rectifieuse. Cet appareil est constitué par un support 9 en forme de fourche agencé pour se fixer à un établi de rectifieuse 6, sur les fourchons 16, 17, dirigés vers le haut, duquel sont prévus des évidements 18 alignes l'un par rapport à l'autre, pour la fixation de l'axe, et par une pièce pivotante munie de deux tourillons 21, 22, agencée pour se mettre en place dans les évidements 18 de fixation de l'axe, qui comporte entre ses deux tourillons un canal 23 destiné à recevoir le foret 8 à réaffûter, lequel canal est placé plus bas que les tourillons de la pièce pivotante 10, la différence de niveau étant fonction de la dépouille désirée, et est orienté obliquement en direction de la surface latérale 5 de la meule, cette orientation étant fonction de l'angle d'inclinaison désiré.
