This section GB/T Part of 124,127.

The partial modification using ISO 603-12:1999 "abrasive products - Dimensions - Part 12. vertical grinder deburring and barren scrub Wheel "(in English).

Taking into account China's national conditions, in the use of ISO 603-12:1999 when this part has made several modifications. About the technical differences have been incorporated into the text in which they are involved and the terms of the margin of a single vertical line identification. It gives a technical difference in Appendix A (Informative appendix) its list of different reasons for reference.

For ease of use, this section also made the following editorial changes.

--- The "this part of ISO 603" with the words "this section";

"." --- With a decimal point instead of a comma as the decimal point, "";

--- Delete international standards foreword.

This Part replaces GB/T 4127-1997 "bonded abrasive grinding wheel shape and size" section of content. The modifications are the following.

--- In order to be consistent with international names such products, the standard of "ordinary abrasive" to "abrasive";

--- Added "Type 4. double hypotenuse Wheel", "16. with tapered core grinding", "18. with cylindrical grinding core", "18R. with half core Spherical grinding "," 19. with an elliptical cone grinding core "provisions;

--- Original Type 53 grinding are defined as "16a type. elliptical cone grinding", "17a type. 60 ° cone grinding", "17b type. round cone grinding" "17c type. truncated cone grinding", "18a type. cylindrical grinding", "18b Type. hemispherical grinding", "19a Type. spherical grinding."

--- Increase the marked products, technical requirements and marking requirements.

This part is proposed by China Machinery Industry Federation.

This part of the National Standardization Technical Committee Abrasives (SAC/TC139) centralized.
