Introduction

This standard is based on the harmonized European standard EN12478.2000 and EN12478.2000/AC.2001 enacted. Harmonized European standards EN12478.2000 and EN12478.2000 AC /.2001 in line with the main provider of basic safety requirements of the Machinery Directive and associated Means EFTA (European Trade Association) rules. This safety standard class C standard GB/T 15706.2-2007 predetermined. Covered by this standard risk category in the "range" has been noted. This standard does not take into account for legacy danger, according GB/T 15706.1-2007 and the relevant provisions of GB/T 15706.2-2007 take appropriate safety precautions. This standard is used for the target machine designers, manufacturers, distributors and importers. In this standard also gives safety information provided by the manufacturer to the user. Machine safety of large-sized CNC machine tools and turning centers Range 1 This standard specifies the safety requirements for CNC lathes and turning centers for general purposes (hereinafter referred to as the machine) to remove the danger and risk reduction And/or measures. This standard identified risk shown in Table 1, Chapter 4 in. This standard applies to. --- 500mm maximum outer diameter greater than the holding means of numerically controlled turning machines and turning centers; --- maximum outer diameter of 500mm or greater than the maximum clamping means from the top horizontal lathes and CNC turning over center of 2000mm. This standard is also applicable to the annex as an integral part of the machine, such as. a workpiece, the tool chuck, workpiece, cutting device and chip Device. This standard is also applicable to form an automatic lathe or turning unit of the processing line, hazard and risk when they produce the individual processing machines When the bed is similar. Additional methods given in this standard is based on the standard references listed. This does not apply to the standard EN12840.2000 related CNC machining required manually controlled (NC) lathe (without programmable control Device). Simple CNC lathe may refer to this standard.
