NF ISO 6779
Acceptance conditions for broaching machines of vertical internal type - Testing of accuracy
La présente norme s'adresse aux utilisateurs et constructeurs de ce type de machines. Elle permet de définir chaque élément principal de la machine et de donner des procédés de vérifications géométriques pour mesurer les écarts tolérés correspondant à des machines d'usage général. Elle ne traite que du contrôle de la précision de la machine. Elle ne concerne ni l'examen de son fonctionnement (vibrations, bruits anormaux, points durs dans ses déplacements d'organes etc.) ni celui de ses caractéristiques (vitesse, avances etc.) examens qui doivent, en général, précéder celui de la précision.
This document specifies, with reference to ISO 230‑1, the geometric tests on vertical internal type broaching machines with vertical Z-axis providing the main cutting motion. It also specifies the applicable tolerances corresponding to the tests mentioned above for normal-accuracy vertical internal type broaching machines. This document explains concepts or configurations and common features of vertical internal type broaching machines. It also provides related terminology and designation of axes. This document deals only with the verification of the accuracy of the broaching machine. It does not apply to the operational testing of the machine (e.g. vibration, abnormal noise, stick-slip motion of components), nor to machine characteristics (e.g. speeds, feeds) as such checks are generally carried out before testing the accuracy.
The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
