Exploring the manufacturing process of diamond saw blades

Diamond saw blades, as a leader in modern industrial cutting, have become the preferred tool for processing hard and brittle materials such as stone, ceramics, and concrete due to their excellent cutting performance and wide range of applications. Huicetool will explore the entire manufacturing process of diamond drill bits and saw blades with everyone today, revealing the technological secrets behind it.

 

Basic composition

Diamond saw blades are mainly composed of three parts: substrate, diamond particles(diamond segment), and metal matrix. The substrate is usually made of high-strength steel as the main support structure of the saw blade. Diamond particles are the "cutting edge" of the saw blade, playing a crucial role in the cutting process with their unparalleled hardness. The metal matrix is responsible for embedding and bonding diamond particles to form a sturdy cutting layer.

manufacturing process

The manufacturing process of diamond saw blades mainly includes sintering, welding, and electroplating.

1. The sintering process can be divided into two types: cold press sintering and hot press sintering. In cold pressing sintering, diamond particles are mixed with metal powder, formed by cold pressing, and then sintered at high temperature to tightly bond the diamond particles with the metal matrix. Hot pressing sintering is the process of pressing and sintering at higher temperatures and pressures to achieve higher bonding strength and more uniform diamond distribution.

 

2. Welding processes mainly include high-frequency welding, laser welding, and brazing. High frequency welding uses a high-temperature melting medium to weld the blade and substrate together, forming a strong bond. Laser welding uses a high-temperature laser beam to melt the contact edge between the cutting edge and the substrate, forming a metallurgical bond with higher strength and accuracy. Brazing is the process of using flame spraying to deposit brazing alloy onto a tool steel substrate, then arranging diamond cloth on the surface of the brazing material, and then induction brazing under high temperature and protective gas to achieve the bonding between diamond and steel substrate.

 

3. Electroplating process is the process of attaching diamond particles to a substrate through electroplating, forming a thin layer of diamond cutting layer. This method is suitable for manufacturing thinner saw blades and has the advantages of low cost and high production efficiency.

manufacturing process

The manufacturing process of diamond saw blades includes multiple steps such as raw material preparation, forming and pressing, sintering or welding, polishing and processing, and quality inspection.

1. Raw material preparation is the first step in manufacturing diamond saw blades. Diamond particles, metal powders, and other auxiliary materials need to be prepared. The grade, particle size, and concentration of diamond particles have a significant impact on the cutting performance of saw blades. Metal powder is used to form a metal matrix, encapsulate and bond diamond particles.

 

2. After mixing diamond particles and metal powder evenly, they are placed in a mold for molding and pressing. Press the mixture into the desired shape and size through cold or hot pressing. During the pressing process, it is necessary to control parameters such as pressure, temperature, and time to ensure the quality of molding and the uniformity of diamond particle distribution.

 

3. The saw blade formed by sintering or welding needs to undergo sintering or welding treatment. In the sintering process, the formed saw blade is placed in a sintering furnace for high-temperature sintering to tightly bond the diamond particles with the metal matrix. In the welding process, the cutting edge is welded to the substrate through methods such as high-frequency welding, laser welding, or brazing.

 

4. Grinding and processing of sintered or welded saw blades require grinding and processing. By using a grinding machine and sandblasting process to treat the surface of the saw blade, remove burrs and uneven parts, and improve the smoothness and cutting performance of the saw blade. At the same time, it is necessary to accurately measure and adjust the size and shape of the saw blade to ensure that it meets the design requirements.

 

5. The final step of quality inspection is quality inspection. Perform visual inspection, dimensional measurement, and cutting performance testing on finished saw blades. Through strict inspection procedures, ensure that the saw blade meets the design requirements and quality standards. Only saw blades that have passed quality inspection can be sold and used from the factory.

 

 

Diamond application fields

Diamond saw blades, as an efficient cutting tool, have a wide range of applications, covering multiple industrial fields. The following are the main application scenarios of diamond saw blades:

1. Stone industry

Diamond saw blades are widely used in the stone industry. It can easily cut hard and brittle materials such as marble, granite, ceramic wall and floor tiles, and concrete products. Due to its convenient operation, high cutting efficiency, and good processing quality, diamond saw blades have become an indispensable tool in stone processing.

 

2. Ceramic industry

Diamond saw blades also play an important role in the ceramic industry. It can cut ceramic materials such as tiles and ceramic panels to meet the processing needs of various ceramic products. Diamond saw blades have high cutting accuracy, ensuring that the size and shape of ceramic products meet design requirements.

 

3. Construction industry

The construction industry is also one of the important application areas of diamond saw blades. In construction, diamond saw blades can be used to cut building materials such as concrete and refractory materials. Its efficient cutting ability and good durability make diamond saw blades highly favored in the construction industry.
