GB/T 42628-2023Machine tools safety - Sawing machines for cold metal (English PDF)

1 Scope

This document is mainly concerned with the use of the various metal sawing machines listed in Chapter 3 (including auxiliary equipment such as workpiece clamping devices, cooling devices, feeding devices, etc:) for major hazards, dangerous situations and events that exist in the process of cold sawing ferrous or non-ferrous metals:

The table in Chapter 4 of this document reveals the significant hazards for metal sawing machines: It stipulates that the manufacturer mainly abides by in the design and manufacture of sawing machines security elements: At the same time, this document is also an essential safety information for the manufacturer to provide the user with regard to the use of the sawing machine:

This document can also be used as a basis for safety requirements for other machining methods (milling, boring, marking, finishing, etc:): For more information, please

See references:

This document deals with noise hazards, but does not provide complete noise test specifications: It is proposed that such specifications be drafted in the next revision of this document:

This document does not include requirements and safety measures for fire and explosion hazards: It will be addressed in the next revision of this document:

This document applies to (metal) sawing machines produced after its implementation:
