Bonded abrasive products - Permissible unbalances of grinding wheels as delivered - Static testing (ISO 6103:2014)

This International Standard specifies the maximum permissible values of unbalances for bonded
abrasive wheels with an outside diameter D ≥ 125 mm and maximum operating speed vs ≥ 16 m/s, in the
as-delivered condition.
It also specifies the method for measuring the unbalance and the practical method for testing whether
a grinding wheel is acceptable or not.
This International Standard is applicable to bonded abrasive wheels in the as-delivered condition.
This International Standard is not applicable to
— diamond, cubic boron nitride or natural stone grinding wheels, or
— centreless control wheels, lapping and disc wheels, ball wheels or glass grinding wheels.
NOTE 1 The values given refer to the grinding wheel itself, independent of any unbalance which may exist in
the balancing arbor or in the means of fastening it to this arbor. These various elements, together with the flanges
or hub-flanges, are assumed to be balanced, homogeneous and free from geometrical defects.
NOTE 2 The effects of unbalance are basically
— additional stresses on the arbor, the machine and its mounting,
— excessive wear of the bearings,
— vibration prejudicial to the quality of machining and increased internal stresses in the grinding wheel, and
increased operator fatigue.

Schleifkörper aus gebundenem Schleifmittel - Zulässige Unwucht von Schleifscheiben im Lieferzustand - Statische Prüfung (ISO 6103:2014)

Diese Internationale Norm legt die maximal zulässigen Unwuchten für verschiedene Formen von Schleif-scheiben aus gebundenem Schleifmittel mit einem Außendurchmesser von D  125 mm und einer Arbeitshöchstgeschwindigkeit vs  16 m/s im Lieferzustand fest.
Darüber hinaus werden geeignete Verfahren zur Messung der Unwucht sowie zur Abnahmeprüfung der Schleifscheibe festgelegt.
Diese Internationale Norm ist anwendbar für Schleifscheiben aus gebundenem Schleifmittel im Lieferzustand.
Diese Internationale Norm gilt nicht für
-   Schleifscheiben mit Diamant, kubischem Bornitrid oder Naturstein oder
-   Regelscheiben beim spitzenlosen Schleifen, Läpp Scheiben und Schleifscheiben mit Tragscheiben sowie Schleifscheiben zum Schleifen von Kugeln oder Glas.
ANMERKUNG 1   Die angegebenen Werte beziehen sich auf die Schleifscheibe selbst, unabhängig von jeder Unwucht, die in der Hilfswelle oder in der Befestigung der Scheibe auf der Hilfswelle auftreten kann. Es wird vorausgesetzt, dass diese verschiedenen Einzelteile zusammen mit den Flanschen oder Aufnahmeflanschen ausgewuchtet wurden und homogen sowie frei von geometrischen Fehlern sind.
ANMERKUNG 2   Die Auswirkungen der Unwucht sind die Ursache für
-   zusätzliche Belastung der Hilfswelle, der Maschine und ihrer Befestigung,
-   außergewöhnliche Abnutzung der Lager,
-   Schwingungen, die das Schleifergebnis beeinflussen, erhöhte innere Spannungen in der Schleifscheibe und fortschreitende Ermüdung des Bedieners.

Produits abrasifs agglomérés - Balourds admissibles des meules en état de livraison - Contrôle statique (ISO 6103:2014)

ISO 6103:2014 spécifie les valeurs maximales admissibles des balourds pour les meules à base d'abrasif aggloméré de diamètre extérieur D ≥ 125 mm et de vitesse maximale de fonctionnement vs ≥ 16 m/s, dans l'état de livraison. Elle spécifie également la méthode de mesurage du balourd et la méthode pratique pour vérifier si une meule est acceptable ou non.
Elle est applicable aux meules à base d'abrasif aggloméré dans l'état de livraison.
Elle n'est pas applicable aux meules à base de diamant, de nitrure de bore cubique, ou en pierre naturelle, ou aux meules d'entraînement sans centre, aux disques et lapidaires de rodage, aux meules à billes ou aux meules pour le travail du verre.

Vezana brusna sredstva - Dopustna neuravnoteženost brusnih in rezalnih plošč ob dobavi - Statično preskušanje (ISO 6103:2014)

Ta mednarodni standard določa največje dopustne vrednosti neuravnoteženosti za vezane
brusilne kolute z zunanjim premerom D ≥ 125 mm in najvišjo hitrostjo obratovanja vs ≥ 16 m/, v stanju kot ob dobavi.
Določa tudi metodo za merjenje neuravnoteženosti in praktično metodo za preskušanje, ali
je brusni kolut dopusten ali ne.
Ta mednarodni standard se uporablja za vezane brusilne kolute v stanju kot ob dobavi.
Ta evropski standard se ne uporablja za
– diamantne brusne kolute ali brusne kolute iz kubnih borovih nitridov ali naravnega kamna ali
– votle kontrolne kolute, preklopne in diskaste kolute, kroglične kolute ali steklene brusne kolute.
OPOMBA 1: Podane vrednosti se nanašajo na sam brusni kolut, ne glede na kakršno koli neuravnoteženost, ki bi lahko obstajala v stojalu ali v načinu pritrditve koluta na stojalo. Ti različni elementi se skupaj s prirobnicami ali prirobnicami pesta obravnavajo kot uravnoteženi, homogeni in brez geometrijskih napak.
OPOMBA 2: Učinki neuravnoteženosti so v osnovi
– dodatne obremenitve na stojalo, stroj in montažo,
– obraba ležajev,
– vibracije, ki so pomembne za kakovost dela s strojem in večje notranje obremenitve v brusnem kolutu, ter večja utrujenost upravljavca.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
