GB/T 41093-2021Machine tools safety - Turning machines (English PDF)

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:
