Les fraises en bout ne sont pas con\u00e7ues pour \u00eatre utilis\u00e9es comme des forets en raison de plusieurs diff\u00e9rences essentielles dans leur conception et leur fonction. Contrairement aux forets, les fraises en bout n'ont pas la g\u00e9om\u00e9trie de pointe sp\u00e9cialis\u00e9e n\u00e9cessaire \u00e0 un amor\u00e7age efficace du trou et ne sont pas optimis\u00e9es pour les forces de coupe axiale ou l'\u00e9vacuation verticale des copeaux. La conception de leur goujure est ax\u00e9e sur la coupe lat\u00e9rale plut\u00f4t que sur la plong\u00e9e, ce qui peut entra\u00eener un colmatage des copeaux et une surchauffe lorsqu'elles sont utilis\u00e9es pour le per\u00e7age. De nombreuses fraises en bout ne sont pas \u00e0 coupe centr\u00e9e, ce qui rend difficile l'amor\u00e7age d'un trou, et elles sont g\u00e9n\u00e9ralement d\u00e9pourvues des canaux de refroidissement internes que l'on trouve dans les tr\u00e9pans, ce qui est crucial pour les applications en trous profonds. En outre, les fraises en bout fonctionnent \u00e0 des vitesses de coupe diff\u00e9rentes de celles des forets et peuvent produire des trous moins pr\u00e9cis ou plus rugueux lorsqu'elles sont utilis\u00e9es pour le per\u00e7age. L'utilisation d'une fraise en bout comme d'un foret peut entra\u00eener une mauvaise qualit\u00e9 du trou, une r\u00e9duction de la dur\u00e9e de vie de l'outil et une rupture ou une d\u00e9viation potentielle de l'outil en raison de l'inad\u00e9quation des forces de coupe. Bien que les fraises en bout puissent parfois \u00eatre utilis\u00e9es pour agrandir des trous existants ou cr\u00e9er des trous peu profonds dans certaines situations, elles ne sont g\u00e9n\u00e9ralement pas adapt\u00e9es ou efficaces en tant qu'outils de per\u00e7age primaires.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
