Page 4 EN 13128:2020 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, 39。 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
