This European Standard specifies the requirements and/or measures to remove the hazards and limit the risks on general purpose numerically controlled turning machines and turning centres which are designed primarily to work cold metal with no access to the work-zone during machining as defined in 3.1 and 3.2 and hereafter referred to as "machines". This standard covers the significant hazards, listed in clause 4. This standard applies to : - numerically controlled horizontal spindle turning machines and turning centres with distance between centres (BC) up to 2 000 mm which are designed to be equipped with workpiece clamping devices up to 500 mm outside diameter; - numerically controlled vertical turning machines, inverted spindle turning machines including pick up machines and turning centres which are designed to be equipped with workpiece clamping device up to 500 mm outside diameter. Larger machines may comply with this standard or shall comply with EN 12478:2000. The standard also applies to ancillary devices, e.g. tools, chucks, workpiece handling devices and swarf handling equipment which are integral to the machine. Where additional processes are involved, this standard can be taken as a basis (see also bibliography annex ). This standard also applies to machines which are integrated into an automatic production line or turning cell where the hazards and risks arising are comparable to those of machines working separately. This European Standard apply for automatic single spindle turning machines but does not apply to automatic multispindle turning machines which are dealt with in prEN 13788:1999. This European Standard does not 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.
