Champ d’application
This standard specifies the safeguarding technical requirements for electro-discharge machines (EDM). It applies to EDM die-sinking machines, EDM wire cutting machines, EDM grinding machines, and EDM perforating machines. It serves as a mandatory compliance benchmark for manufacturers and importers of these specific machine tools in China. The standard does not apply to non-electro-discharge metal cutting equipment.
Exigences techniques
The standard comprehensively addresses the mechanical hazards associated with EDM equipment, requiring the elimination of sharp edges and the implementation of reliable mechanical limit devices to prevent unexpected falls or squeezing. Manufacturers must ensure that moving parts, such as wire storage drums and vertical spindles, have fail-safe braking mechanisms during power loss or emergency stops. Regarding fire and explosion protection, the standard mandates strict controls for machines using flammable dielectric fluids. It requires the use of immersion processing with specific fluid level heights corresponding to the working current. The standard also dictates the integration of automatic fluid level and temperature monitoring devices interlocked with the machining process. For electrical safety, the requirements ensure protection against direct electrical contact, particularly concerning the pulse power output lines and tool electrodes. The standard also sets specific ergonomic limits, such as maximum operating forces for handwheels and appropriate installation heights for control panels and instruments.
Méthodes d’essai
Compliance is verified through a combination of visual inspections, manual checks, and specific functional tests. Key testing procedures include electrical tests to verify the continuity of the protective grounding circuit, insulation resistance, and dielectric withstand capability, referencing GB/T 5226.1. Additionally, fire prevention tests are conducted to validate the reliability and functionality of fluid level controllers, fluid temperature controllers, and automatic fire extinguishing interfaces under simulated machining conditions.
