Multi-layer diamond segment

There are many types of diamond segments. Multi-layer diamond segment is one of the most common segment structures, which means the diamond nodules formed by mixing diamond particles and metal powders of different properties in a certain proportion and stacking them in layers, adding a metal powder layer or iron sheet in the middle, and forming them after high-temperature and high-pressure sintering.
The structure of the multi-layer diamond segment generally consists of a base layer, an intermediate layer and a cutting layer. The cutting layer contains a higher concentration of diamond particles to ensure that the segment has excellent cutting performance. The middle layer and the base layer contain diamond particles with a lower concentration (or no diamond, and part of the middle layer uses iron sheets), which mainly play a role in increasing the chip removal capacity and cutting efficiency of the segment. The structural design and manufacturing process of the multi-layer segment have excellent performance in terms of cutting efficiency, durability, and stability, and are widely used in the cutting and processing of hard materials such as stone, ceramics, and glass.

So what are the advantages of the multi-layer diamond segment compared with other diamond segments? The following aspects are summarized according to the structure of the multi-layer segment compared with the traditional sandwich segment:

Higher cutting efficiency: The multi-layer diamond segment has higher cutting efficiency, which can complete cutting tasks faster and more accurately, saving time and labor costs.

Better cooling effect: The multi-layer diamond segment adopts a multi-layer structure design, which can quickly reduce the temperature of the segment during the cutting process, ensures that the segment is in a healthy working state for a long time, and improves the cutting quality.

Higher safety: The multi-layer diamond segment adopts a multi-layer structure, which avoids the breakage and chipping of the segment, and improves the work safety.

Wider scope of application: The multi-layer diamond segment can be designed with different layers and ratios according to different materials and uses, which is suitable for cutting various materials and has a wider application scope. For example, hard and fragile cutting objects such as hard-to-cut ceramics and dekton.

Higher economic benefits: The high-efficiency cutting and long life of the multi-layer diamond segment reduce the production cost and the cost of replacing the segment, and bring higher economic benefits.

However, the multi-layer diamond segment also has disadvantages: the manufacturing process of the multi-layer diamond segment is relatively complicated. What are the techniques and difficulties in the production process of the multi-layer segment? The following is a detailed introduction, mainly including the following aspects:

Structural design of the segment: The multi-layer segment needs to design a reasonable structure, including the bonding layer and the substrate layer between different diamond layers, as well as the structure of the substrate and the mechanical clamping.

Material selection: The bonding layer between different diamond layers needs to choose a suitable material to ensure a firm bond between the diamond layers, while taking into account material cost and performance.

Preparation process: The preparation of the multi-layer segment needs to be pressed and sintered many times. The conditions of each pressing and sintering need to be strictly controlled to ensure the firm bond between the diamond layers. At the same time, it is necessary to ensure the stability of the size and shape of the entire segment.

Tool inspection: The prepared multi-layer diamond segment needs to undergo strict quality inspection, including the inspection of the appearance, size, hardness and sharpness of the segment, so as to ensure that the quality and performance of the segment meet the requirements.
In general, the manufacturing process of multi-layer diamond segment is relatively complicated, and requires fine control of materials, processes, design and other aspects in order to produce high-end diamond segment products with stable quality and excellent performance.
