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 edge and outline finishing machines for natural stone. Edge finishing machines
are processing the usually rough edges of the workpiece with one or more spindles fitted with grinding tools which
are aligned synchronously or asynchronously towards the edge of the workpiece. Edge finishing machines can be
of table or belt design.
This European Standard does not deal with significant hazards associated with noise.
This European Standard does not deal with:
metal grinding machines;
wood grinding machines;
hand-held grinding machines;
machines intended for operation in a potentially explosive atmosphere;
upstream and downstream conveying elements for transporting the workpieces.
This standard deals with all significant hazards, hazardous situations and events relevant to edge 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 document is not applicable to edge finishing machines which are manufactured before the date of publication
of this document by CEN.

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
edge finishing machine
the edge finishing machine is a stationary machine for milling, grinding, polishing and cut-off grinding the edges of
workpieces of marble, granite or other stone-similar material. During the work process water is always used as a
cooling lubricant which also prevents the formation of dust caused by the process. The machines are intended for
the use of abrasives and cut-off wheels with diamond impregnation
3.2
table edge finishing machine
a stationary machine with a worktable on which the workpieces are fixed for processing. The work spindles are
guided along the workpiece on a rail-carriage combination. The worktable is fixed.
The particular work spindles will be generally switched on by the machine control when in working position relative
to the workpiece and switched off when leaving the workpiece.
Before the delivery the respective work spindle is put into rotation and the cooling lubricant supply is activated. This
process is repeated in reverse order when the carriage is turned off

Figure 1 — Table edge grinding machine
3.3
belt edge finishing machine
a belt edge finishing machine is a stationary machine with a conveyer belt on which the workpieces are guided in-
line along the work spindles by horizontal and vertical guide rolls. These machines are designed for the intermittent
as well as for the continuous transport of the workpieces. The workpieces are guided on the conveyer belt by
means of non-driven top pressure rolls with pneumatic or elastic force.
The particular work spindles will be generally switched on by the machine control when in working position relative
to the workpiece and switched off when leaving the workpiece. Before the delivery the respective work spindle is
put into rotation and the cooling lubricant supply is activated. This process is repeated in reverse order when the
carriage is turned off
