The importance of diamond saw blade substrate

Diamond saw blades rotate at high speed to cut stone, and a substrate with a certain vibration frequency resonates when the additional frequency matches the natural frequency. This requires the substrate to have a high elastic limit and yield strength ratio.

Secondly, due to the unevenness of the substrate or poor installation of the diamond saw blade, lateral pressure is generated during cutting, causing the substrate to repeatedly bend, resulting in a decrease in substrate stiffness or fatigue strength.

The matrix should also have high stiffness and fatigue strength; On the other hand, during the cutting process of diamond saw blades, the substrate must withstand cyclic cutting pressure and impact force. Therefore, the matrix should also have high tensile strength and a certain impact toughness.

The chemical composition and heat treatment state of steel determine the mechanical properties and service life of the product. For products that require high mechanical properties such as diamond saw blade matrix, carbon steel or alloy steel with high carbon content is usually used for manufacturing, and quenched and tempered at medium temperature to ensure the microstructure with high composite performance requirements.

In addition, stress relief annealing and stabilization treatment are also important processes that cannot be ignored in the substrate manufacturing process.
