20、, Switzerland and United Kingdom. BS EN 12417:2001+A2:2009 EN 12417:2001+A2:2009 (E) 4 Introduction This European Standard is a type C standard as stated in EN 2921. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this typ
21、e C standard take precedence. Machining centres 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 cut
22、ting tools, especially when being rapidly rotated in the spindle, or being swung from a tool magazine to the spindle during power-operated tool changing, or from contact with fastmoving workpieces, is of great importance. When poweroperated mechanisms are provided for workpiece transfer, they can al
23、so create hazardous situations during loading/unloading and workpiece alignment or clamping. Total enclosure of the work zone using guards during cutting is practicable for smaller machines. The requirements for access to the work zone of large machines used for the processing of a wide range of wor
24、kpiece configurations can require that operators are safeguarded by other means (e.g. perimeter fencing, protective devices at the operating position). Pendant controls enable operators to move around the machine, especially large machines, and to view the work zone, the load/aligning, clamping, cut
