GB/T 40330-2021 is the English-translated version of 机床安全固定式磨床.

GB/T 40330-2021 is the Chinese standard "Safety of machine tools - Stationary grinding machines". Its scope clause reads: This document specifies the following types of stationary grinders that complete metal processing by grinding to eliminate hazards or reduce risks and/or Measures. ---1 category.

Manually controlled grinders with no power drive shaft and no digital control. ---2.Manually controlled grinders with power drive shafts and limited digital control capabilities if applicable. ---3 category. digital control grinder.

Note 1.For detailed information about the classification of grinders, see the definitions in 3.1 and 3.4. Note 2.The requirements of this document usually apply to all types of grinders.

If some requirements only apply to a certain type of grinder, it will be clearly indicated which type of grinder. This document is also applicable to machine tools or grinding units integrated in automatic production lines, because the hazards and risks associated with such machine tools are independent of each other.

The working machine tool is quite. This document does not apply to fixed honing machines, polishing machines and abrasive belt grinders, nor does it apply to IEC 61029-2-4 and IEC 61029-2-10 Of portable power tools.

1 Scope

This document specifies the following types of stationary grinders that complete metal processing by grinding to eliminate hazards or reduce risks and/or

Measures.

---1 category. Manually controlled grinders with no power drive shaft and no digital control.

---2.Manually controlled grinders with power drive shafts and limited digital control capabilities if applicable.

---3 category. digital control grinder.

Note 1.For detailed information about the classification of grinders, see the definitions in 3.1 and 3.4.

Note 2.The requirements of this document usually apply to all types of grinders. If some requirements only apply to a certain type of grinder, it will be clearly indicated which type of grinder.

This document is also applicable to machine tools or grinding units integrated in automatic production lines, because the hazards and risks associated with such machine tools are independent of each other.

The working machine tool is quite.

This document does not apply to fixed honing machines, polishing machines and abrasive belt grinders, nor does it apply to IEC 61029-2-4 and IEC 61029-2-10

Of portable power tools.
