When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions o
22、f this type 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
23、moving cutting 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, t
24、hey can also 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 ra
