GB/T 41093-2021 Machine tools safety—Turning machines
Basic Information
Scope
This document specifies the requirements and methods for eliminating hazards or reducing risks in the design of the following types of metal cutting lathes and turning centers:
——Category 1: Manually controlled lathes without CNC functions.
——Category 2: Manually controlled lathes with limited CNC functions.
——Category 3: CNC lathes and turning centers.
——Category 4: Single-axis or multi-axis automatic lathes.
Note 1: For more detailed information on machine tool classification, see 3.4, and for mandatory and optional configurations of operating modes, see 3.3.
Note 2: The requirements of this document generally apply to all types of lathes. If certain requirements only apply to a specific type of lathe, it has been explicitly indicated which type of lathe they apply to.
Note 3: Hazards arising from other metal cutting processes (such as grinding and laser processing) are described in other standards (see references).
The important hazard factors listed in Chapter 4 of this document also apply to auxiliary equipment integrated with the machine tool (such as workpieces, tools and workpiece clamping devices, loading and unloading equipment, and chip removal devices).
This document also applies to machine tools or turning units integrated into automatic production lines, as the hazards and risks arising in this situation are similar to those of standalone machine tools.
This document includes essential safety-related information provided by manufacturers to users. See Figure 2 in GB/T 15706—2012, which illustrates the responsibilities of manufacturers and users regarding operational safety.
It is the user's responsibility to identify certain hazards (such as fire and explosion) and minimize the associated critical risk factors (such as whether the centralized control exhaust device is functioning properly).
Where other processing (milling, grinding, etc.) is involved, this document only mentions th
