ÖNORM EN 12478

This European Standard specifies the requirements and/or measures to remove the hazards and limit the risks on general purpose numerically controlled large turning machines and turning centres which are designed primarily to work cold metal as defined in 3.1 and 3.2 and herein after referred to as "machines". This standard covers all significant relevant hazards which are listed in clause 4. This standard is applies to : numerically controlled large vertical turning machines and turning centres which are equipped with work clamping plate exceeding 500 mm outside diameter. numerically controlled horizontal spindle turning machines and turning centres with distance between centres exceeding 2 000 mm or which are equipped with work clamping devices exceeding 500 mm outside diameter. The standard also applies to ancillary devices (e.g. for workpieces, tools and work clamping devices handling devices and chip handling equipment, etc.) which are integral to the machine. This standard also applies also to machines which are integrated in an automatic production line or turning cell where the hazard and risks arising are comparable to those of machines working separately. Where additional processes are involved this standard can be taken as a basis (see also annex bibliography) This standard does apply to NC turning machines with machining facilities under manual control which are dealt with in EN 12840:2000. This standard applies to machines which are manufactured after the date of issue of this standard.
