Foreword
This European Standard has been prepared by Technical Committee CEN/TC 143 "Machine tools - Safety",
the secretariat of which is held by SNV.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by October 2001, and conflicting national standards shall be withdrawn at
the latest by October 2001.
This European Standard has been prepared under a mandate given to CEN by the European Commission and
the European Free Trade Association, and supports essential requirements of EC Directive(s).
This standard has been prepared to provide one means of conforming with the essential requirements of the
Machinery Directive and associated EFTA regulations.
Annexe A is normative. Annexes B, C, D and ZA are informative. This Standard also contains a Bibliography.
For relationship with EC Directive(s), see informative Annex ZA, which is an integral part of this standard.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark,
Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain,
Sweden, Switzerland and the United Kingdom.

0 Introduction
This European standard is a type C standard as stated in EN 292–1.
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.
Milling machines present a wide range of hazards, not least from their wide application as rotating tool,
'stationary' workpiece machine tools, for general purpose cutting of cold metal work material.
Protection of operators and other persons from contact with moving cutting tools, especially when being rapidly
rotated in the spindle or from contact with fast–moving workpieces, is of great importance.
When power–operated mechanisms are provided for workpiece transfer, they can also create hazardous
situations during loading/unloading and workpiece alignment or clamping.
On automatic milling machines, total enclosure of the work zone using guards during cutting is the preferred
method of safeguarding. Where this is not practicable (e.g. due to size of the workpiece, its geometry, or its
special characteristics), operators may be safeguarded by other means (e.g. perimeter fencing, protective
devices at the operating position). Operators may also benefit from pendant controls which enable them to
move about the machine.
The significant hazards covered by this standard are those listed in table 1. The safety requirements and/or
protective measures to prevent or minimize those hazards identified in table 1 and procedures for verification
of these requirements or measures are found in clause 5 (tables 2, 3, 4 and 5).
The figures in annex C are examples only and are not intended to illustrate the only interpretation of the text.

1 Scope
1.1 This standard specifies the technical safety requirements and measures to be adopted by persons
undertaking the design, construction and supply (including installation and dismantling, with arrangements for
transport and maintenance) of milling machines (see 3.1) including machines capable of performing boring
operations (see 3.5).
Machines covered by this standard include but are not limited to:
– knee and column type milling machines (see figures C.1, C.2);
– bed–type milling machines (see figure C.3);
– multi–spindle milling machines (see figures C.4 and C.5);
– plano–milling machines (see figures C.4 and C.5);
– profile and contouring milling machines (see figure C.6),
– milling and boring machines (see figure C.7).
1.2 This standard takes account of intended use including reasonably foreseeable misuse, maintenance,
cleaning, and setting operations. It presumes access to the machine from all directions. It describes means to
reduce risks to operators and other exposed persons.
1.3 This standard also applies to workpiece transfer devices when they form an integral part of the machine.
1.4 This standard deals with significant hazards relevant to milling machines when they are used as intended
and under the conditions foreseen by the manufacturer (see clause 4).
1.5 Hazards arising from other metal working processes (e.g. grinding, turning, forming, EDM, laser
processing) are covered by other standards (see Bibliography).
1.6 Milling machines with automatic tool changing capabilities are not covered by this standard
(see prEN 12417:1996).
1.7 This standard is not applicable to milling machines which were manufactured before the date of publication
by CEN of this standard.
