Description
Exécution:
Pour la réalisation d’alésages avec tolérances dans l’acier ou les matériaux à copeaux courts. Usinage complet fiable sans centrage séparé ni processus d’alésage en aval. Autocentrage nettement amélioré grâce à la pointe pyramidale supplémentaire pour une concentricité et une précision de tolérance optimales de l’alésage généré. Deux arêtes de perçage et quatre arêtes d’alésage pour une qualité d’état de surface attractive de la paroi de l’alésage.
Données de tolérance:
H7: exécution pour tolérance d’alésage H7.
+/− 0,003 mm: tolérance de fabrication ou de coupe du ⌀ nominal DC.
