--- Deleted "EN954-1:1996" in the normative reference document, and added the "document number and content" of the document in the text

Deleted together [see Chapter 2, Chapter 3, 5:1:1, 5:8b)1), 5:11a), 5:11b)], because EN954-1:1996 is no longer applicable, now

The line GB/T 16855:1-2018 has covered its content;

--- Modify "EN954-1:1996, 3:2" to "GB/T 16855:1-2018, 3:1:2" (see 3:1:10), because EN954-1:1996

No longer applicable, the current GB/T 16855:1-2018 has covered its content;

--- Deleted "IEC 60529" in the normative reference document, because the number of the document in the main text is incorrect, which is inconsistent with its expression [(see

5:3a)2)];

--- References ISO 13732-1 and EN13478 moved into Chapter 2 Normative references:

The following editorial changes have been made to this document:

--- Modified the file name:

--- Change the "X" in the original international standard to "*" in this document and add a note (see 5:16), which is in line with our customs after the change:

--- Deleted the original international standard "Source: Reference [33]" (see Figure B:2 below): The content of this article is therefore irrelevant to this document:

--- Change "MTTFd and B10d" in the original international standard to "MTTFD and B10D" in this document respectively (see Appendix F): after change

Keep consistent with the symbols in the GB/T 16855:1-2018 standard:

1 Scope

This document specifies requirements and methods for eliminating hazards or reducing risks in the design of the following types of metal cutting lathes and turning centers:

--- Class 1: Manually controlled lathes without numerical control functions:

--- Category 2: Manually controlled lathes with limited numerical control functions:

--- Category 3: CNC lathes and turning centers:

--- Category 4: single- or multi-spindle automatic lathes:

Note 1: See 3:4 for more detailed information on the classification of machine tools, and see 3:3 for the mandatory configuration and optional configuration of the operating mode:

Note 2: The requirements of this document generally apply to all types of lathes: If certain requirements only apply to a certain type of lathe, which type of lathe has been clearly indicated:

Note 3: Hazards from other metal cutting processes (such as grinding and laser processing) are described in other standards (see References):

The important risk factors listed in Chapter 4 of this document also apply to auxiliary equipment integrated with the machine tool (such as workpieces, tools and workpieces):

clamping devices, handling equipment and chip removal devices):

This document also applies to machine tools or turning cells integrated into automatic production lines, since the dangers and risks arising in this situation are different from the unique

The machine in the standing state is similar:

This document contains information about safety that is essential for the manufacturer to provide the user: See Figure 2 in GB/T 15706-2012,

Illustrate the responsibilities between the manufacturer and the user regarding operational safety:

It is the user's responsibility to detect certain hazards (eg fire and explosion) and minimize the critical risk factors associated with them (eg centralized control

whether the exhaust system is working properly):

Where other processing (milling, grinding, etc:) is involved, this document only mentions the basic content of safety requirements; see references for more details:

This document applies to machines manufactured after the release date:
