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 the diamond circular saw blade matrix, and in conjunction with
GB/T 11270:1 "Diamond circular saw blades made of superhard abrasives - Part 1: Welded saw blades" and GB/T 11270:2 "Diamond circular saw blades made of superhard abrasives"
"High-quality diamond circular saw blades - Part 2: Sintered saw blades" are harmonized, and GB/T 16457 "Diamond circular saw blade substrate" is planned to consist of the following two parts
constitute:
---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:
Diamond circular saw blade base
Part 2: For sintered saw blades
