。ISCHE NORM EN 13128 April 2020 + A1 March 2020 ICS English version Safety of machine tools Milling machines (including boring machines) S233。s und Bohr Fr228。 I S C HES KOM I TEE F 220。 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 (. due to size of the workpiece, its geometry, or its special characteristics), operators may be safeguarded by other means (. 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. Page 5 EN 13128:2020 1 Scope 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 ) including machines capable of performing boring operations (see ). Machines covered by this standard include but are not limited to: – knee and column type milling machines (see figures , )。 – profile and contouring milling machines (see figure ), – milling and boring machines (see figure ). 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. This standard also applies to workpiece transfer devices when they form an integral part of the machine. 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). Hazards arising from other metal working processes (. grinding, turning, forming, EDM, laser processing) are covered by other standards (see Bibliography). Milling machines with automatic tool changing capabilities are not covered by this standard (see prEN 12417:1996). This standard is not applicable to milling machines which were manufactured before the date of publication by CEN of this standard. 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.
