The structure and characteristics of the sandwich diamond segment

The sandwich diamond segment is a high-precision cutting tool, which is formed by sintering layers of diamond sheets and metal powder according to a certain ratio. It has a very special structure and many excellent properties, and is widely used in the field of cutting hard materials.
One. Structure of Sandwich Diamond Segment
The structure of the sandwich diamond segment is divided into three layers, which are diamond layer, alloy layer and matrix layer. Among them, the diamond layer is composed of large-grain diamond sheets and small-grain diamond sheets arranged in a certain proportion, and the diamond sheets are connected by sintering through metal powder. The alloy layer is composed of hard metal powder and solder, which are sintered on both sides of the diamond layer to connect the diamond layer and the matrix layer. The base layer is made of high-strength metal material, which plays a role in supporting the entire segment.

Two. Characteristics of Sandwich Diamond Segment
1. High hardness
Diamond is the hardest material known so far, its hardness reaches 10 Mohs hardness, and it has very obvious advantages in the cutting of hard materials. The diamond layer in the sandwich diamond segment has very high hardness, which can quickly break the surface of the material during the cutting process, thus improving the cutting efficiency and quality.

2. Good wear resistance
The sandwich diamond segment has excellent wear resistance, can maintain a long-term cutting effect under high-speed friction, and can effectively prolong the service life of the diamond segment.

3. High stability
The diamond layer and the alloy layer of the sandwich diamond segment are connected together by sintering, which has good bonding strength and stability, and can maintain good rigidity and stability during the cutting process, ensuring the stability and accuracy of the cutting effect.

4. High cutting efficiency
The sandwich diamond segment has high hardness and wear resistance, and can quickly break the surface of the material during the cutting process, thereby improving the cutting efficiency and quality, and at the same time reducing the chance of stone breaking during cutting.

Compared with sandwich segments, the advantages of sandwich segments are also very obvious:
 (1) The overall performance of the diamond segment is excellent: the diamond segment with a sandwich structure is composed of a diamond layer, a brazing layer and a substrate layer, and each layer plays a different role. The diamond layer has excellent hardness and wear resistance, which can keep the segment edge sharp during the cutting process; the brazing layer can tightly connect the diamond layer and the base material layer, improving the overall stability and strength of the diamond segment; The base material layer plays a supporting role, which can ensure the mechanical performance and rigidity of the cutter head.

(2) High cutting efficiency: the diamond segment with sandwich structure has excellent cutting efficiency and can quickly cut materials of various hardness. The excellent hardness and wear resistance of the diamond layer ensure the sharpness and life of the blade, and the good connection of the brazing layer and the support of the substrate layer ensure the overall stability and rigidity of the blade.

(3) Wide application range: the diamond segment with sandwich structure can be applied to cutting materials of various hardness, including stone, ceramics, glass, concrete, metal, etc.

(4) Long service life: due to the hardness and wear resistance of the diamond layer, the diamond segment of the sandwich structure has a long service life, which can reduce the number of replacement of the diamond segment, improve production efficiency and reduce production costs.
All in all, the diamond segment with sandwich structure has broad application prospects in modern processing, manufacturing, construction and other fields, especially in the field of cutting difficult materials, and has an irreplaceable role. During use, it is necessary to control the cutting speed and cutting depth to avoid wear and damage of the diamond segment caused by excessive cutting. At the same time, the diamond segment needs to be cleaned and maintained regularly to ensure the normal service life of the diamond segment.
