Brief description of ten professional knowledge points of diamond segment

The following are ten professional knowledge points related to diamond segments:
1. The manufacturing process and working principle of the diamond segment;
Manufacturing process: the diamond segment is a cutting tool made of the ultra-high hardness of diamond. Its manufacturing process mainly includes the selection of metal powder and diamond, and the need to ensure that the particle size and distribution of diamond particles are uniform during the manufacturing process. The structure of the diamond segment and stable quality. The working principle of the diamond segment is to use the high hardness, high thermal conductivity and high wear resistance of diamond abrasive grains to cut various materials, such as stone, ceramics, metal, etc., by rotating the diamond at high speed.
2. Classification and application of diamond segment;
The diamond segment is mainly classified according to the application, which is divided into stone cutting segment, glass cutting segment, wood cutting segment, concrete cutting segment, tile cutting segment, metal cutting segment and so on.

3. The effect of the nature, shape and size of diamond particles on the performance of the diamond segment;
The nature of diamond refers to the grade, which mainly determines the cutting life of the diamond segment. In terms of shape, it can determine the cutting efficiency and sharpness of the cutter head. The size of the diamond determines the cutting quality, such as coarse particles and rough cutting surface.

4. Production processes such as sintering and welding of diamond segments;
Hot pressing is one of the main methods of preparing diamond segments. The process is to put diamond particles and metal powder together under high temperature and high pressure for processing. In terms of segment welding, it is mainly divided into laser welding and high-frequency welding. Among them, high-frequency welding is widely used in the stone industry, and laser welding is mostly used for concrete cutting pieces.

5. Selection of welding materials for diamond segments;
Laser welding does not require welding materials. Below we are talking about high-frequency welding. The materials for high-frequency welding diamond segments can be nickel solder, copper solder, silver solder, etc. Among them, nickel solder has stable performance in high temperature environment and can be used for welding at high temperature, but the price is relatively high; copper solder is relatively low in price and has good thermal conductivity, which is suitable for welding in some medium and low temperature environments; Silver solder are more expensive, but the welding quality is more stable than copper solder.

6. The influence of the material, hardness and wear resistance of the diamond segment on the cutting effect;
The harder the diamond segment, the better it can resist wear and deformation, so it has better cutting accuracy and cutting quality. The wear resistance determines the life of the diamond segment. Generally, the higher the wear resistance, the longer the life of the diamond segment.

7. The impact of the toughness, tensile strength and breaking strength of the diamond segment on the cutting safety;
The toughness of the diamond segment refers to the ability of the diamond segment not to break or break under the action of external force. High toughness can improve the service life and safety of the diamond segment and reduce the occurrence of accidents. Tensile strength refers to the ability of the diamond segment to resist breaking under the action of tensile stress, which is one of the strength indicators of the diamond segment. High tensile strength means the bit is more durable and less likely to break. Fracture strength refers to the minimum strength of the diamond segment to break under the action of bending stress. High breaking strength can make the diamond segment more durable, improve cutting efficiency and safety.

8. The wear mechanism and influence of diamond segment;
Diamond segment wear has a great influence on the cutting effect. When the wear is excessive, the cutting ability of the diamond segment will be reduced, and burrs will appear on the cutting surface of the cutting object, which will affect the quality and process requirements of the product.

9. Fault analysis and fault diagnosis of the diamond segment;
In the fault analysis and fault diagnosis of the diamond segment, many factors need to be considered. First of all, it is necessary to check whether the installation of the segment is correct, and whether the material, hardness, size and shape of the diamond segment meet the requirements. Secondly, it is necessary to check whether the material, shape, size, hardness and other factors of the cutting workpiece are suitable for cutting with a diamond segment. It is also necessary to consider the conditions of use, such as cutting speed, coolant usage, vibration during cutting and other factors.

When we perform fault analysis and fault diagnosis, multiple methods are usually required. For example, a visual inspection of the diamond segment can be carried out to observe the wear of the blade, the quality of the cut edge, etc. Tools can also be used to measure the diamond segment. For example, the size and shape of the diamond segment can be measured using tools such as a micrometer and a microscope. At the same time, experiments can also be carried out, such as adjusting the cutting speed, coolant usage, etc., to observe the changes in the cutting effect.

Finally, it is necessary to take corresponding solutions according to the results of the failure analysis. For example, replace the diamond segment, adjust the cutting conditions, replace the coolant, etc. At the same time, it is necessary to maintain and maintain the diamond segment in time, and regularly clean, lubricate and grind the diamond segment to ensure the service life and cutting effect of the diamond segment.
10. Maintenance of the diamond segment, including cutting edge wear, cleaning, lubrication, etc.;
Edge wear and repair: the cutting edge of the diamond segment will gradually wear out with the increase of use time, and it needs to be repaired regularly to keep it sharp. When the cutting edge is worn, it can be trimmed with a grinding wheel or abrasive.

Cleaning: during use, some impurities will adhere to the diamond segment. If it is not cleaned in time, it may affect the cutting effect. Therefore, it is very necessary to clean the diamond segment regularly.

Lubrication: during the cutting process, the diamond segment needs to move continuously. The use of lubricant can reduce wear and friction and prolong the lifespan of the diamond segment.

Storage: when the diamodn segment is not used for a long time, it needs to be stored to avoid the diamond segment from being damp, heated or mechanically damaged. When storing, the diamond segment should be placed in a moisture-proof and dust-proof place.
