What is the line in the middle of the diamond segment?

The earliest diamond segment did not have the middle line. People put the powder and diamond directly into the mold and sintered directly. Since these materials are integrally formed, the earliest segment has no middle line. But with the advent of the cold press, people can pre-process the powder into tablets, that is, let the powder undergo a tableting process at room temperature to form a block, which greatly reduces the size of the sintering process and greatly reduces the size. Its structure and performance are also more stable.

However, in the process of cold pressing, excessively large agglomerates will have unstable weight and uneven distribution of diamonds, and when the finished product is reused, it is difficult to shear, so cold pressed agglomerations are generally Mainly small agglomerates, and the length and width of the agglomerates are consistent with the segment structure of the finished product. In the later process, the cold-pressed agglomerates are arranged in sequence and then sintered to finally form the finished diamond segment. However, in the segment processed in this way, the layer-to-layer fusion is very complete, and the middle part of the line cannot be seen. Such a segment will have a big problem. First of all, in terms of cutting efficiency, since the middle part of the segment cannot form a cutting groove, when the knife is cut, an excessively large cutting surface will definitely lead to a decrease in cutting efficiency, although it is kept longer Longevity, but the high price and poor sharpness make this segment slowly unfavorable by the mainstream stone cutting market.

Later, it was discovered that if a layer of matrix powder without diamond powder is added in the middle of the cold-pressed sheet, the matrix powder without diamond will be quickly consumed during the cutting process, forming a line of recessed lines, and cutting the stone In the process of cutting, a very obvious working layer and non-working layer are formed, which greatly improves the cutting efficiency, and the non-working layer is concave. During the cutting process, the cooling water will easily cool the cut part of the segment, which greatly improves The segment is deformed or unstable due to the high heat generated by friction, and the debris after the stone is cut will flow out from the cut part as the water is washed. There are obviously many lines in the middle of this kind of interlayer segment. These lines are actually the matrix of metal powder that is not doped with diamond.

Then, when the diamond segment developed further, it was found that if iron pieces are added to the cold pressed sheet, a good cutting effect can also be achieved. Such a segment structure becomes a cold pressed sheet, iron sheet, cold pressed sheet, and iron sheet. Sheets, cold-pressed sheets..., because of the closeness of the iron element and the molecular properties of diamond, the iron sheet is quickly consumed in the segment with such a structure, which not only maintains the sharpness, but also greatly reduces the material cost. The line in the middle of this type of segment is actually an iron sheet. The thicker the iron sheet, the better the sharpness and the shorter the life; the thinner the iron sheet, the lower the sharpness, but the longer the life.

Therefore, the diamond segment is also called diamond agglomerate. It can be divided into three layers and two lines, five layers and three lines, seven layers and five lines, nine layers and seven lines, etc., and it can also be used without a non-working layer in the middle of the agglomeration. The structure can also be divided into five layers with two lines, seven layers with three lines and so on.
