Diamond Segment Pattern And Structure

The diamond segment is a tool commonly used for cutting stone, mainly used on circular saw blades to grind stone through the rotation of the saw blade. Due to different types of stone, different stone cutting machines, different types of saw blades, different rigidity of saw blades and different cutting requirements. As a result, diamonds need to constantly adapt to different cutting environments. So what are the patterns and structures of the segment?

There are many types of segments. At present, the commonly used large-size saw blade segments on the market mainly have the following shapes:

M shape diamond segment: the serrated part of this segment presents an M-shaped curve. The advantage of this design is that when the segment cuts the stone at the initial stage, there are two small cutting teeth at the top of the M. During the cutting process. Due to the reduction of the cutting area, the cutting ability of the segment is enhanced when the same cutting force is applied. This can help the saw blade to cut quickly and play a role in quickly opening the cutting edge. M-type segment is mainly used for granite cutting. Mainly because the granite segment does not need to be diamond opened, which avoids taking a long time on the diamond opening in the early stage of cutting. If the M-shaped segment is used, the time period of diamond opening can be greatly shortened, and labor costs and mechanical startup costs can be saved.



K-shape diamond segment: K-type segment is mainly used for mining. The most obvious feature of this segment is the shape of a K at the top. During the cutting process, the front tip of the K quickly cuts the stone. The working principle of this kind of segment and M-type segment is relatively the same. However, due to the smaller cutting edge of the K-type segment, the cutting edge effect is better at the initial cut. However, since the tail area of the K-type segment is less useful during the cutting process, most of the material is wasted, so the cutting life is shorter. In addition, because the impact force of the K-edge cutting stone is too large in the early stage, the segment will be very prone to segment loss. So gradually, this kind of segment is less produced at present.

Arc-shaped segment: the arc-shaped segment is for better cutting of softer stones. The arc-shape segment is the best in terms of cutting quality. Mainly because the arc adopts an arc-shaped cutting angle. During the cutting process, the arc surface is very smooth, which acts as a buffer when cutting. But the disadvantages are also very obvious, that is, the life of this kind of segment is often not long enough, the sharpness is not high enough, and it is difficult to cut some hard stones.

Parallel segment: the most direct manifestation of the parallel segment is that the serration part is a parallel structure. During the cutting process, the relative cutting is relatively smooth. Due to the relatively slow cutting process in the early stage, most of the parallel segments need to be diamond opened in the early stage of use. Mainly used for cutting marble and soft granite.



Apart from discussing the shape of diamond segment, we can have a look of the structure of the segment. The structure of the segment mainly includes two types: sandwich structure and layer structure.

The segment with sandwich structure divides the segment into three layers, which are: working layers on both sides and a working layer in the middle. The edge material on both sides of the segment and the intermediate material used in the middle layer are different materials. The difference lies in the diamond grit used by the segment, and the powder is roughly the same. Under such a structure, the carcass is extremely tightly bonded during the sintering process. Since the middle layer also has a certain cutting ability, such a segment has a good performance in terms of cutting life, especially for cutting marble and soft granite, which has a good performance.



The sandwich segment adopts a multi-layer structure segment structure shape. The segment is mainly manifested in the following points: 1. The non-working layer in the segment inter-layer is iron sheet or powder, and does not contain diamond, so it can save some costs. 2. The more inter-layers of the diamond segment, the higher the cutting sharpness and the stronger the cutting performance. 3. If the diamond inter-layer is made of powder, the life can be appropriately improved, but it will increase some costs.

All in all, there are many ways to make diamond segments, but it still depends on different cutting objects and customer needs.
