EN 13128:2001+A2:2009 (E) 4 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).

The safety requirements and/or measures and information for use contained in clauses 5 and 7 are based on the risk assessment and deal with the identified hazards by either eliminating them or reducing the effects of the risks they generate. 4.2 The risk assessment assumes foreseeable access from all directions, as well as unexpected start–up. Risks to both the operators and other persons who can have access to the hazard zones are identified, taking into account hazards which can occur under various conditions (e.g. commissioning, set-up, production, maintenance, repair, decommissioning) during the life of the machine. The assessment includes an analysis of the effect of failure in the control system. 4.3 In addition, the user of this standard (i.e. the designer, manufacturer, supplier) shall validate that the risk assessment is complete for the machine under consideration with particular attention to: the intended use of the machine including maintenance, setting and cleaning, and its reasonably foreseeable misuse; the identification of the significant hazards associated with the machine.
