Introduction

Diamond circular saw blades are currently divided into two types of products, welded saw blades and sintered saw blades, due to different manufacturing processes. These two types of products are in terms of performance and technology. There are big differences in technical requirements. In order to scientifically and reasonably standardize and coordinate the technical content of diamond circular saw blades, GB/T 11270 "Super Hard Abrasive Products Diamond Circular Saw Blade" is planned to consist of the following two parts. ---Part 1.Welding saw blades; ---Part 2.Sintered saw blade. Diamond circular saw blades for super-abrasive products Part 2.Sintered Saw Blade

1 Scope

This document specifies the code and marking of the sintered diamond circular saw blade, the basic dimensions of the base and the teeth, technical requirements, test methods, and inspection rules Rules, signs, packaging, transportation and storage. This document is applicable to sintered diamond circular saws for cutting and processing materials such as stone, concrete, refractory materials, asphalt, carbon, ceramics, and glass. Blade (hereinafter referred to as saw blade).
