Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

This document is Part 1 of GB/T 16457 "Diamond Circular Saw Blade Base". GB/T 16457 has released the following parts.

---Part 1: For welding saw blades;

---Part 2: For sintered saw blades.

This document partially replaces GB/T 16457.1-2009 "Superhard material saw blade base dimensions - Part 1: Used in buildings and civil engineering Mechanical cutting of engineering materials" and GB/T 16457.2-2009 "Saw blade base dimensions for super-hard materials - Part 2: Used in buildings and civil engineering Hand-held cutting of engineering materials. This document is based on GB/T 16457.1-2009 and integrates GB/T 16457.2-2009 and welding Contents related to the saw blade base. Compared with GB/T 16457.1-2009, in addition to structural adjustments and editorial changes, the main technical changes as follows.

a) Changed the scope (see Chapter 1, Chapter 1 of the 2009 edition);

b) The code name and mark have been changed (see Chapter 4, Chapter 2.1, 2.2, and Chapter 3 of the 2009 edition);

c) The dimensions and requirements have been changed (see 5.4, Appendix A, 2.3 of the 2009 edition);

d) Added requirements for safety, appearance, surface roughness, geometric tolerance, and tension (see 5.1, 5.2, 5.3, 5.5, and 5.6);

e) Added requirements for test methods, inspection rules, marking, packaging, transportation and storage (see Chapter 6 ~ Chapter 8).

Introduction

Due to different manufacturing processes, diamond circular saw blades are currently divided into two categories. welded saw blades and sintered saw blades. These two types of products are very Technical requirements vary widely. In order to scientifically and reasonably standardize the technical content of diamond circular saw blade substrates, and in line with GB/T 11270.1 "Diamond circular saw blades for superhard abrasive products - Part 1: Welding saw blades" and GB/T 11270.2 "Diamond circular saw blades for superabrasive products" in line with the "Stone Circular Saw Blades Part 2: Sintered Saw Blades", GB/T 16457 "Diamond Circular Saw Blade Base" is intended to consist of the following two parts.

---Part 1: For welding saw blades. The purpose is to establish technical specifications for the substrate used in welding process diamond circular saw blades.

---Part 2: For sintered saw blades. The purpose is to establish the technical specifications for the matrix used in sintering process diamond circular saw blades.
