Escopo e aplicabilidade

GB 18568-2001 establishes the safeguarding specifications for general-purpose machining centres. It is applicable to machines that utilize computer numerical control (CNC) to perform various machining operations. This standard is mandatory for all manufacturers and suppliers of machining centres entering the Chinese market. It does not apply to special-purpose machines designed exclusively for non-cutting applications.

Requisitos técnicos

This standard comprehensively outlines safety requirements across multiple hazard categories. For mechanical dangers, it mandates strict safety distances and reliable interlocking guards to prevent crushing, shearing, and entanglement risks, particularly in tool magazines and workpiece clamping areas. Manufacturers must ensure that all moving parts are adequately enclosed or safeguarded. Regarding electrical and thermal hazards, the standard requires compliance with relevant national electrical codes to prevent electric shock, electromagnetic interference, and burns from high-temperature components. The CNC system must be designed to prevent unintended start-ups and ensure safe failure modes. Control systems must be designed so that a single fault does not lead to a dangerous machine state. The standard also addresses ergonomic and material hazards. It specifies requirements for adequate workspace lighting (minimum 300 lux at the spindle front), acceptable noise limits, and the management of hazardous fluids, oil mist, and dust. Manufacturers are required to provide comprehensive user information and clear safety warnings regarding residual risks.

Métodos de ensaio

Compliance is evaluated through a combination of visual inspections, functional checks, and specific physical tests. Key evaluations include noise pressure level measurements under no-load conditions, verification of protective device integrity, and testing of emergency stop response times. Manufacturers must also conduct insulation resistance and residual voltage tests for electrical components, alongside temperature rise assessments for hydraulic systems.

Perguntas frequentes

What products are regulated under GB 18568-2001?

GB 18568-2001 applies to general-purpose machining centres. It specifies safety requirements to address major hazards associated with these machines. It is mandatory for manufacturers exporting machining centres to China.

How does GB 18568-2001 relate to general machine tool safety standards?

The standard is based on GB 15760-1995 (General safeguarding specification for metal-cutting machine tools) but is specifically tailored to the structural characteristics and operational risks of machining centres, such as automatic tool changers and multi-axis movement.

Are there specific noise limits defined in GB 18568-2001?

The standard sets specific noise limits depending on the machine's weight. For machines weighing 10 tonnes or less, the limit is 83 dB(A), and for machines over 10 tonnes, the limit is 85 dB(A). Measurements must be conducted under no-load conditions.

The summary above provides a high-level overview of GB 18568-2001.
