Diamond saw blade is a commonly used tool for cutting various hard materials, with its main feature being sharp and wear-resistant. Its cutting principle is to use diamond particles embedded on a metal substrate. Diamond has a higher hardness than most materials, so it can effectively cut hard materials, including concrete, bricks, stone, ceramics, glass, and metal. The working principle of diamond saw blade is to rotate the saw blade to make diamond particles friction and cut on the surface of the material, achieving the cutting goal. It can be used under both dry and wet conditions, with wet use being more common as water can lower the temperature of the saw blade and material, reduce dust generation, and extend the lifespan of the saw blade. The design and manufacturing of diamond saw blades are very precise, and their quality directly affects cutting efficiency and quality. Common diamond saw blades come in different sizes, shapes, and uses, such as continuous blades, segmented blades, laser welding blades, etc. Suitable saw blades can be selected according to specific cutting needs. When using diamond saw blades, it is necessary to pay attention to safety measures, including wearing appropriate protective equipment, ensuring stable installation of saw blades and tools, following correct operating methods, etc., to prevent accidental injury and ensure work efficiency.
