Coupling bionic diamond circular saw blade and preparation method thereof

The invention discloses a coupling bionic diamond circular saw blade and a preparation method thereof. The diamond circular saw blade comprises a circular saw blade base body, water tank structures onthe outer edge of the circular saw blade base body and coupling bionic sawtooth segment structures evenly distributed between adjacent water tanks. Each coupling bionic sawtooth segment is of a coupling structure designed on the basis of the body surface abrasion-resistant non-smooth form and the body surface damage self-regeneration function of a scapharca subcrenata, the top end structure of each sawtooth segment is prepared into a groove array similar to the body surface of the scapharca subcrenata, a hidden groove is designed in each sawtooth segment, and an abraded working layer is madeto self-regenerate a non-smooth working layer. The circular saw blade is suitable for cutting machining of hard and brittle materials such as rock, reinforced concrete and semiconductors, has the characteristics of being high
