Maschinen und Anlagen zur Gewinnung und Bearbeitung von Naturstein - Sicherheit - Anforderungen für Flächenschleifmaschinen

Machines et équipements pour l'exploitation et l'usinage de pierres naturelles - Sécurité - Prescripitions relatives aux machines de finition de surface

La présente norme s’applique aux machines fixes de finition de surface fonctionnant de maniere continue et aux machines de finition de surface se déplaçant sur des rails, ci-apres dénommées machines, qui sont utilisées pour meuler (polir) les surfaces horizontales de dalles brutes habituellement sciées grossierement, en pierre dure comme le granit ou d’autres pieces usinées similaires a la pierre.
Ces machines sont conçues pour fonctionner avec des tetes de meulage sur lesquelles l’outil approprié  le bloc de meulage (de polissage)  est fixé au moyen d’un support.
La présente norme traite tous les phénomenes dangereux, situations et événements dangereux significatifs applicables aux machines de finition de surface lorsqu’elles sont utilisées normalement et lorsqu’elles sont utilisées dans des conditions de mauvaise utilisation raisonnablement prévisibles par le constructeur (voir article 4). La présente norme spécifie les mesures techniques appropriées pour éliminer ou réduire les risques liés aux phénomenes dangereux significatifs.
La présente Norme européenne ne traite pas :
-   les machines a meuler le métal ;
-   les machines a meuler le bois ;
-   les machines mobiles disposées sur un train de roulement progressant sur le sol ;
-   les meuleuses portatives ;
-   les machines conçues pour fonctionner dans une atmosphere explosible ;
-   les éléments de convoyage amont et aval pour le transport des pieces usinées.
La présente Norme européenne ne traite pas les phénomenes dangereux significatifs liés au bruit.
Le présent document ne s’applique pas aux machines fabriquées avant sa date de publication par le CEN.

Introduction
This document is a type C standard as defined in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B standards,
the provisions of this type C standard take precedence over the provisions of the other standards, for
machines that have been designed and built according to the provisions of this type C standard.
1 Scope
This standard applies for stationary surface finishing machines in a continuous operation and surface finishing
machines to be moved on rails, in the following called machines, which are used to grind (polish) horizontal
surfaces of raw hard stone slabs being normally roughly sawn, e.g. granite and other work pieces similar to
stone.
These machines are provided to be operated with grinding heads on which the proper tool – the grinding
(polishing) block – is seated in a holder.
This standard deals with all significant hazards, hazardous situations and events relevant to surface finishing
machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable
by the manufacturer
(see clause 4). This standard specifies the appropriate technical measures to eliminate or reduce risks arising
from the significant hazards.
This European Standard does not deal with:
 metal grinding machines;
 wood grinding machines;
 mobile machines on a running gear, which is running on the ground;
 hand-held grinding machines;
 machines intended for operation in a potentially explosive atmosphere;
 upstream and downstream conveying elements for transporting the workpieces.
This European Standard does not deal with significant hazards associated with noise.
This document is not applicable to machinery which are manufactured before the date of publication of this
document by CEN.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications.
These normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to
this European Standard only when incorporated in it by amendment or revision. For undated references the
latest edition of the publication referred to applies (including amendments).

3 Terms and definitions – Symbols and abbreviated terms
For the purposes of this document, the definitions given in EN ISO 12100 apply. Additional definitions
specifically needed for this document are added below :
3.1
surface finishing machine with mobile transversal bridge (track machines)
machine with stationary work piece table and a movable bridge on a machine track equipped with mobile
grinding tool slides for grinding (polishing) horizontal surfaces of stone slabs by an appropriate grinding
(polishing) head as tool. During the grinding (polishing) process the tool is cooled by water. Additionally the
water serves also for suppressing the development of dust during operation.
The machine can be equipped with :
 automatic grinding (polishing) head change system with tool – magazine;
 grinding (polishing) head change system with bayonet locking;
 accessory units for milling;
 accessory units for polishing

2 running gear 7 drive of longitudinal adjustment
3 drive of lateral adjustment 8 tool slide
4 drive of grinding spindle 9 tool
5 control desk 10 tool magazine

3.2
surface finishing machine with longitudinal bridge and belt conveyor (continuous operating machine)
machine with belt conveyor table and a longitudinal bridge for grinding (polishing) the horizontal surface of
stone slabs with an appropriate grinding (polishing) head as tool. During the grinding (polishing) process the
tool is cooled by water. Additionally the water serves also for suppressing the development of dust during
operation.
