Abstract

The invention discloses a composite diamond saw blade for ceramic cutting and a preparation method thereof, belonging to the technical field of ceramic material cutting. The composite diamond saw blade includes a saw blade substrate and a diamond cutter head. The saw blade substrate is made of 75Cr1 material. The diamond cutter head is composed of an outer layer I, an intermediate layer and an outer layer II along the axial direction of the saw blade substrate. The outer layer of the cutter head is made of fine-grained high-concentration diamond, the carcass material is made of a material with stronger wear resistance, the inner layer of the cutter head is made of coarse-grained low-concentration diamond, and the carcass is made of a material with weaker wear resistance. The diamond will greatly improve the sharpness, the middle layer has a low concentration and the carcass has weak performance, thus forming a cutting groove in the middle. The outer layer has fine diamond particles, so cutting ceramics will not cause edge bursting, and the outer carcass has strong wear resistance. With high diamond concentration, 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 composite diamond saw blade for ceramic cutting and a preparation method thereof. The prepared composite diamond saw blade is used for cutting ceramic materials. 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 diamond saw blade is composed of a disc-shaped substrate and a diamond 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 saw blade is required to have good cutting performance. [0004] Diamond saw blades have the adv...
