Description
Technical Field
The utility model relates to a circular saw blade technical field specifically is a circular saw lamellar body with amortization groove.
Background
The circular saw blade is a cutting tool for processing blanks of materials such as stone, wood, metal, plastics and the like, and the high-speed circular saw blade is a saw blade containing a large amount of carbon, tungsten, molybdenum, vanadium and other elements and is widely applied to the building and furniture industries. At present, circular saw blades at home and abroad are basically formed by punching or processing a whole steel plate in other modes. When hard materials are cut, the surface of the saw block has large friction with the cut surface of the cut material, and under the condition of high-speed rotation, the sawteeth collide with the cut material to generate sound, the sound wave of the sound wave is transmitted on the whole circular saw blade, so that other parts which are not cut resonate according to the sound wave frequency of the sound wave, great noise is generated, noise pollution is generated, and the health of people is influenced.
