Abstract

Cet ensemble porte-fraise pour pièce à main de fraise dentaire comprend un rotor formé d'une turbine 9a et d'un tube 15b. Ce dernier comporte un épaulement intérieur 21. Le mandrin est fait d'une pièce présentant un épaulement extérieur complémentaire de l'épaulement 21. L'alésage du mandrin comprend deux parties 23 et 24 ajustées à glissement sur la queue de la fraise à tenir et une partie centrale, qui comporte l'épaulement et est percée de fenêtres longitudinales de manière à pouvoir se resserrer sur la queue de la fraise, par effet de came entre les épaulements du mandrin et du tube lorsqu'on visse le mandrin dans le tube. Dans ce but, le mandrin présente un trou carré 25 dans lequel on engage une clé mâle et le tube présente des encoches 31 dans lesquelles s'engagent des dents du corps extérieur de la clé.This burr holder assembly for a dental burr handpiece comprises a rotor formed of a turbine 9a and a tube 15b. The latter comprises an internal shoulder 21. The mandrel is made of a piece having an external shoulder complementary to the shoulder 21. The bore of the mandrel comprises two parts 23 and 24 fitted to slide on the shank of the cutter to be held and a central part, which comprises the shoulder and is pierced with longitudinal windows so as to be able to tighten on the shank of the milling cutter, by camming between the shoulders of the mandrel and of the tube when the mandrel is screwed into the tube. For this purpose, the mandrel has a square hole 25 in which a male key is engaged and the tube has notches 31 in which teeth of the outer body of the key engage.
