GB/T 40330-2021 Safety of machine tools—Stationary grinding machines

Scope

This document specifies the requirements and/or measures for eliminating hazards or reducing risks of fixed grinding machines used for metal processing by grinding, in the following categories:
——Category 1: Manually controlled grinding machines without power-driven shafts and without numerical control.
——Category 2: Manually controlled grinding machines with power-driven shafts and, if applicable, with limited numerical control capabilities.
——Category 3: Numerically controlled grinding machines.
Note 1: For detailed information on the classification of grinding machines, see the definitions in Sections 3.1 and 3.4.
Note 2: The requirements of this document generally apply to all types of grinding machines. If certain requirements only apply to a specific type of grinding machine, it will be explicitly stated which type of grinding machine they apply to.
This document also applies to machine tools or grinding units integrated into automatic production lines, as the hazards and risks generated by such machine tools are comparable to those of standalone machine tools.
This document does not apply to fixed honing machines, polishing machines, and belt grinding machines, nor to portable power tools that comply with IEC 61029-2-4 and IEC 61029-2-10.
