What is a diamond saw blade? And Application ?


What is a diamond saw blade? A diamond saw blade is an extremely hard cutting tool that offers more advantages compared to ordinary saw blades made of materials like aluminum alloy. It is harder and has greater hardness. Today, we will explore diamond saw blades, discussing their principles, structure, manufacturing processes, and applications.


Principles of Diamond Saw Blades

Why is a diamond saw blade hard?

Diamond is one of the hardest substances in the world, possessing high Mohs hardness. This allows diamonds to cut through materials with lower hardness than diamonds, including stone, metal, and wood.

Why does a diamond saw blade have strong cutting ability?

Because diamond saw blades are coated with numerous diamond particles on their surface. These diamond particles directly contact the material being cut, enabling swift cutting.

Structure of Diamond Saw Blades

Diamond saw blades are generally divided into three layers: diamond particle layer, blade matrix, and original cutting edge design. Each of these different structures brings about distinct effects. Below, I will describe these three differences.

1. Diamond particle layer: Diamond saw blades have a surface coating of diamond particles. These particles are bonded to the blade's matrix using metal or synthetic resin, forming a sturdy cutting edge.

2. Blade matrix: The blade matrix provides structural support for the diamond particles and is typically made of metal or synthetic resin materials. The choice of matrix depends on the type of material being cut and its requirements.

3. Cutting edge design: Diamond saw blades can have different cutting edge designs, such as continuous edge, segmented edge, or embedded edge. Different designs are suitable for various cutting tasks and material types.

Manufacturing Processes of Diamond Saw Blades

The production of diamond particles in diamond saw blades requires advanced technology because diamond particles are usually prepared through the chemical vapor deposition method. This method yields diamond particles with higher concentration.

In the manufacturing process, the pre-designed diamond particles are evenly installed on the blade's matrix. They are then fixed to the matrix through high-temperature and high-pressure treatment. Finally, the blade undergoes grinding and polishing with grinding wheels to ensure its sharpness.

Applications of Diamond Saw Blades

Diamond saw blades find applications in various industries such as construction and stone industry, metal processing, glass and ceramic manufacturing, optoelectronics, automotive manufacturing, and aerospace. Thus, diamond saw blades are widely used across different sectors.


Above, I have introduced the functionality of diamond saw blades and their advantages and benefits. They are extremely hard cutting blades with high hardness, capable of cutting even harder objects such as metals, which significantly improves production efficiency.
