Compared with GB/T 4127.16-2007, in addition to structural adjustments and editorial changes, the main technical changes are as follows.

a) The dimensions of the flat cutting wheel (type 41) have been changed (see 4.1, 3.1 of the 2007 edition);

b) The dimensions of the cymbal-shaped cutting wheel (type 42) have been changed (see 4.2, 3.2 of the 2007 edition);

c) Deleted the requirements (see Chapter 5 of the 2007 edition).

This document is modified to adopt ISO 603-16:2022 "Bonded abrasive tools — Dimensions — Part 16: Cut-off wheels for hand-held power tools".

The technical differences between this document and ISO 603-16:2022 and their reasons are as follows.

--- ISO 525 (see Chapter 4) has been replaced by the normative reference GB/T 2484 to adapt to my country's technical conditions;

--- Added the size series of flat cutting wheels (type 41) (see 4.1) to conform to the actual situation in my country;

--- Added the size series of cymbal-shaped cutting wheels (type 42) (see 4.2) to conform to my country's actual situation.

The following editorial changes have been made to this document.

--- Deleted the imperial size representation of the outside diameter in the international standard;

--- Deleted the note in 4.2 of the international standard;

--- Deleted references to international standards.

Introduction

In order to facilitate the production, trade, application and technical exchange of bonded abrasives and make rational use of resources, it is necessary to establish a standardized bonded abrasive tool scale.

Bonded abrasives have various shapes and uses. Products with the same shape may have different uses, and products with the same use may also have different with the development of bonded abrasives industry, the advancement of technology and the change of market demand, its shapes and uses are constantly enriched, and its size is constantly increasing.

The size system of bonded abrasive tools is becoming increasingly large, and it is becoming increasingly difficult to establish a size system of bonded abrasive tools through a single standard, which is no longer realistic.

Since.1999, ISO/TC29/SC5 has established a new bonded abrasive tool size system through scientific and reasonable classification and released ISO 603 series standards. GB/T 4127 "Dimensions of bonded abrasives" has adopted ISO 603 series standards since its second revision.
