Abstract

The invention discloses a preparation method of a composite ceramic cutting blade, and belongs to the technical field of ceramic material cutting and machining. A diamond tool bit of the ceramic cutting blade is formed by sequentially compounding an outer layer I, an intermediate layer and an outer layer II in the axial direction of a saw blade base body; and during preparation, an outer layer I pressing sheet, an outer layer II pressing sheet and an intermediate layer pressing sheet are firstly subjected to cold pressing and molding, then, the outer layer I pressing sheet, the intermediate layer pressing sheet and the outer layer II pressing sheet are sequentially placed in a hot-pressing die to be hot-pressed and sintered into a whole to obtain the diamond tool bit, and finally, the toolbit is welded to the saw blade base body in a brazing manner. According to the preparation method of the composite ceramic cutting saw blade, the diamond tool bit with the three-layer structure is designed, a specific preparation process is adopted, the intermediate layer coarse-grain diamond can greatly improve the sharpness when a ceramic material is cut, a cutting groove is formed in the middle, the outer layer cannot generate an edge breakage phenomenon during cutting due to the fact that the diamond grain size is fine, the wearing speed of the outer layer is slower than that of the innerlayer so as to form two cutting edges, and the cutting blade is ensured to be stabler and sharper during cutting.

Description

technical field [0001] The invention relates to the technical field of cutting and processing of ceramic materials, in particular to a preparation method of a composite ceramic cutting piece. 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, Cutting discs are required to have good cutting performance. [0004] Ceramic cutting discs have the advantages of high hardness and good wear resistance. However, in ceramic p...
