Description

TECHNICAL FIELD

[0001] The utility model relates to diamond processing technical field, concretely relates to a cutter specially used for cutting oilstone abrasive. BACKGROUND

[0002] In the field of industrial processing, especially when cutting materials with abrasive components such as oilstone, traditional woodworking saws often face many challenges. Oilstone, due to its abrasive components, hardness and wear resistance far exceed ordinary wood, which makes it extremely difficult to cut with ordinary woodworking saws. When cutting oilstone, ordinary woodworking saw blades not only suffer severe wear, but also quickly lose their sharpness, resulting in low sawing efficiency and increased frequency of replacing saw blades, thereby increasing production costs.

[0003] The original design of ordinary woodworking saw blades is to deal with relatively soft wood and other conventional materials, and their materials and structures are not suitable for high-hardness abrasive materials. When the saw blade comes into contact with the oilstone, the abrasive components, like fine sand, constantly rub the surface of the saw blade, causing the saw blade to wear out quickly. This wear not only shortens the service life of the saw blade, but also may affect the precision and quality of the cut due to the instability of the saw blade. In addition, frequent replacement of saw blades not only takes time, but also increases the labor intensity of workers and reduces production efficiency.

[0004] In the face of this technical defect, it is particularly urgent to develop a targeted product designed specifically for cutting oilstone with abrasive components.

[0005] This product needs to have higher wear resistance and stronger cutting ability to meet the cutting needs of high-hardness materials such as oilstone. CONTENT OF THE UTILITY MODEL
