This International Standard specifies the requirements and/or measures to eliminate the hazards or reduce the risks in the following groups of stationary grinding machines which are designed primarily to shape metal by grinding: Group 1: Manually controlled grinding machines without power operated axes and without numerical control. Group 2: Manually controlled grinding machines with power operated axes and limited numerically controlled capability, if applicable. Group 3: Numerically controlled grinding machines. NOTE 1 For detailed information on the groups of grinding machines, see the definitions in 3.1 and 3.4. NOTE 2 Requirements in this International Standard are, in general, applicable to all groups of grinding machines. If requirements are applicable to some special group(s) of grinding machines only, then the special group(s) of grinding machine(s) is/are specified. This International Standard covers the significant hazards listed in Clause 4 and applies to ancillary devices (e.g. for workpieces, tools and workpiece clamping devices, handling devices), which are integral to the machine. This International Standard also applies to machines which are integrated into an automatic production line or grinding cell inasmuch as the hazards and risks arising are comparable to those of machines working separately. This International Standard also includes in Clause 7 a minimum list of safety-relevant information which the manufacturer has to provide to the user. See also ISO 12100:2010, Figure 2, which illustrates the interaction of manufacturer’s and user’s responsibility for the operational safety. The user's responsibility to identify specific hazards (e.g. fire and explosion) and reduce the associated risks can be critical (e.g. whether the central extraction system is working correctly). Where additional metalworking processes (e.g. milling, turning, laser processing) are involved, this International Standard can be taken as a basis for safety requirements. For specific information on hazards arising from other metalworking processes, which are covered by other International Standards, see the Bibliography. This International Standard applies to machines that are manufactured after the date of issue of this International Standard. This International Standard does not apply to stationary honing, polishing and belt grinding machines and not to transportable motor-operated electric tools in accordance with IEC 61029-2-2 and IEC 61029-2-10.
