Ordinary circular saws are important cutting tools for cutting hard materials such as stone. However, there is still a major flaw in the use of circular saws, which has long plagued stone processing enterprises. This is a huge noise pollution caused by saws in the process of cutting stones, which is not only harmful to the physical and mental health of operators, but also seriously affects people in the surrounding areas. Normal life. Recently, an overseas company has introduced a highly efficient and powerful silencer circular saw.
At present, in order to eliminate noise, the technical measure commonly used is to install a muffler cover in the entire processing system of the circular saw. However, due to the large changes to the processing system, the investment cost is high and it is not convenient to implement it on a large scale. So the company followed this technology. It is understood that the innovative technology of this college silencer circular saw is on the concentric circle of the circular saw blade, and several "S"-shaped holes are continuously formed around the hole, and the filler is filled with rubber, polyurethane or lead filler. The unique process is covered with polyester, polyurethane or silicone resin on both sides of the slot, and extends radially from the central portion of the substrate at the center of the substrate, with at least one or two slots present. The use shows that since the silencing circular saw has a hole groove, and a filler and a resin layer and a metal powder layer are formed, it can be effectively transmitted to each side of the substrate, thereby achieving a significant noise elimination effect.
