The so-called noise of the metal band saw is actually the noise generated by the machine itself. In layman's terms, it is the vibration, impact, friction, and noise generated by the band saw blade, the sawing machine and the workpiece being sawed. This kind of irregular sound produced when the metal band sawing machine is working is collectively referred to as noise. When the noise exceeds 400HZ, it will threaten the health of the staff. If people are in such a working state for a long time, it will cause great harm to people's hearing over time. This should not be underestimated. Generally speaking, the noise of the metal band sawing machine is mainly due to the improper operation of the sawing machine or the failure of the parts. When the noise occurs, we should stop the inspection to find out the cause of the noise. First notice that you must cut off the power first, then open the protective cover, and turn the saw wheel by hand to see if the band saw blade hits a foreign object or the saw dust is stuck in the tooth. If the band saw blade is okay, you can remove the band saw blade and run the host to see if this is the cause. In addition to improper operation and component failure, the vibration of the metal band saw is also a factor. 1. Mechanical noise caused by friction and vibration between the metal band saw and the metal material. During the working process of the metal band saw, the size of the pollution depends on the shape and hardness of the material. 2. The wear of the bearing, because the tension is not suitable, the saw blade and the bearing do not fit together, which will cause shaking and vibration. 3. Cut off the power and check the speed and drop scale of the saw blade on the saw. Generally, the speed of hard materials should slow down and the drop should be slower. In addition, the guide block that clamps the saw blade is too tight, and the distance between the fixed guide arm and the movable guide arm of the sawing machine is too large to cause vibration. The above are the several factors of noise produced by metal band sawing machines. With the continuous development of the industry, there are more and more types of sawing tools, and the noise pollution is getting more and more serious. So everyone should pay more attention to these points in daily use. Reduce noise as much as possible.
