---Added "provide warning signs" [see 5.2.1c)4) and 5.2.2e)4)], because domestic manual machine tools cannot do 1), 2), 3)

Requirements to adapt to the actual situation of most SMEs;

---Added "(except the lateral feed mechanism of external cylindrical grinding machine tool)" [see 5.9e)1)i] to adapt to the horizontal

The structural characteristics of the feed mechanism;

---Added "If the material of the abrasive protective cover is made of a rolled steel plate with a tensile strength of not less than 415N/mm2, the wall thickness of the circumferential plate is tp

The wall thickness ts of the side panel and the side panel can be used not less than the value listed in Table A.8; if the Q235 rolled steel plate with better welding performance is selected (resistant

The tensile strength is 375N/mm2~460N/mm2), and its wall thickness should not be lower than the value listed in Table A.8; when the tensile strength is not low

When using 150N/mm2 gray cast iron, its wall thickness should not be lower than the value listed in Table A.9; when malleable cast iron is selected, its wall thickness should not be lower than that listed in Table A.9.

Should be lower than 2 times the value listed in Table A.8."(See A.3.2.1 and Table A.8, Table A.9) to adapt to the actual situation of my country's grinding machine industry

Happening.

This document has made the following editorial changes.

---The standard name was changed to "Safety Fixed Grinding Machine for Machine Tool";

---Deleted the description part in the scope (see Chapter 1).

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.
