Un outillage sur mesure peut rapidement faire grimper vos coûts de fabrication. Savoir tirer le meilleur parti de l’outillage standard peut vous faire économiser beaucoup d’argent lorsque vous produisez des pièces sur mesure.
Pour réduire le besoin d’outillage personnalisé, nous avons créé trois tableaux résumant les dimensions standard des forets utilisés dans l’usinage CNC.
Tableaux des dimensions des forets
Les trois tableaux ci-dessous indiquent les dimensions standards des forets, les fractions de pouce et le calibre des fils. Lors de la conception de pièces à commande numérique comportant des trous de foret, il est utile, et souvent nécessaire, de faire correspondre ces dimensions standard.
Si vous concevez des trous qui ne respectent pas ces tolérances, vous aurez peut-être besoin d’un outillage spécialisé pour fabriquer vos pièces.
