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.
