Abstract

The invention discloses a ceramic cutting saw blade and a preparation method thereof, belonging to the technical field of ceramic material cutting. The diamond head of the ceramic cutting saw blade is composed of the outer layer I, the middle layer and the outer layer II sequentially compounded along the axial direction of the saw blade substrate, and the outer circumference is provided with a cooling groove; the diamond particle size in the outer layer material of the cutter head is 60‑80 Mesh, the diamond particle size in the middle layer material of the cutter head is 40-50 mesh; the compressive strength of diamond is 18-24kg. And the outer layer of the cutter head is made of high-concentration diamond, the matrix is ​​made of strong wear-resistant material, the inner layer of the cutter head is made of low-concentration diamond, and the carcass is made of material with weaker wear resistance. It is greatly improved, and a cutting groove is formed in the middle. The outer layer will not produce edge bursting due to the fine diamond particle size cutting. The outer layer has strong wear resistance, and the outer layer will wear slower than the inner layer, forming two cutting edges to ensure Smoother and sharper cutting.

Description

technical field [0001] The invention relates to the technical field of ceramic material cutting, in particular to a ceramic cutting saw blade and a preparation method thereof. Background technique [0002] In today's construction industry, due to the country's stricter control over mining, the amount of natural stone has been greatly reduced, and ceramic materials have become important materials in decoration, and the ceramic processing industry has become more and more extensive. [0003] The ceramic cutting disc is composed of a disc-shaped substrate and a diamond cutter head connected to the outer edge of the substrate. It is widely used in the cutting of ceramic materials. It is mainly used for trimming and cutting in ceramic cutting. However, due to the high hardness of ceramics , the cutting piece is required to have good cutting performance. [0004] Ceramic cutting chips have the advantages of high hardness and good wear resistance. However, in ceramic processing, f...
