Abstract

Il comprend une tête adaptable dans la broche de la machine-outil et intérieurement un long alésage pour le logement à libre coulissement d'une barre porte-outil; une bague vissée extérieurement sur une partie filetée de ladite tête autorise de par son alésage épaulé, d'une part, le logement d'une pluralité de joncs toriques en matière souple avec rondelles métalliques intercalaires sollicités en appui lors du vissage de la bague par l'extrémité de la tête, de manière à permettre par pression, leur écrasement et par suite, leur retreinte diamétrale pour le blocage élastique et anti-vibratoire de la barre, quelle que soit sa position longitudinale de débordement.
