The Impact of High-Iron and Low-Iron Matrix Bodies on the Diamond Segment Holding Force in Diamond Blades

The influence of high-iron matrix body and low-iron matrix body on the gripping force of diamond segments in a diamond blade is a critical aspect in cutting applications. Below is a detailed explanation of how high-iron and low-iron matrix bodies affect the gripping force of diamond segments:

1. Definition and Characteristics of High-Iron Matrix Body and Low-Iron Matrix Body:
High-Iron Matrix Body: This typically refers to the matrix body of a diamond blade that contains a significant amount of metal powder, particularly with a high iron content. This matrix provides additional strength and rigidity to the blade.

Low-Iron Matrix Body: Conversely, a low-iron matrix body contains less iron or employs other alloys or materials. These matrices usually lack the same level of strength and rigidity as high-iron matrices.

2. Influence of High-Iron Matrix Body on Diamond Gripping Force:
Enhanced Gripping Force: High-iron matrix bodies often result in better adhesion of diamond particles, providing a firmer gripping force. This helps in securely retaining the diamond particles on the blade, reducing the risk of detachment.

Improved Wear Resistance: Due to their hardness, high-iron matrix bodies offer enhanced resistance to wear during cutting operations. This means that diamond particles maintain their sharpness for longer periods, increasing the blade's lifespan.

Suitability: High-iron matrix bodies excel in cutting hard materials such as granite and concrete due to their increased rigidity and durability.

3. Influence of Low-Iron Matrix Body on Diamond Gripping Force:
Flexibility: Low-iron matrix bodies are relatively softer and more flexible, making them better suited for applications where adaptability to certain shapes or materials is necessary.

Smooth Cutting: The lower hardness of low-iron matrix bodies can result in smoother cutting, reducing surface roughness and damage to materials.

Suitability: Low-iron matrix bodies are typically employed when the material being cut does not demand high rigidity, such as softer stones or plastics.

4. Considerations:
Manufacturing Choice: Diamond blade manufacturers often choose between high-iron and low-iron matrix bodies based on the requirements of the cutting task. This choice depends on the needed rigidity, wear resistance, and gripping force.

Material Adaptation: Different materials may require different types of matrix bodies. For instance, cutting hard materials like granite may benefit from a high-iron matrix body.

Maintenance and Durability: While high-iron matrix bodies offer increased wear resistance and longer blade life, low-iron matrix bodies might require more frequent replacement. The overall cost of the blade needs to be considered.

5. Conclusion:
High-iron and low-iron matrix bodies each have their advantages, and the choice depends on the nature of the cutting task and the desired performance characteristics. Understanding their differences and how they affect diamond gripping force aids in selecting the right blade type, thereby improving cutting efficiency and blade longevity. Proper operational and maintenance practices should also be employed based on the specific circumstances of blade use.
