Analysis on abnormal sound of metal circular saw blade during cutting

In the process of metal circular saw cutting, if there is abnormal noise, most of the factors are caused by the instability of the saw blade. How to prevent this kind of failure, we must first clearly understand the essential reason.

Analysis on the factors causing abnormal sound of metal circular saw blade:

When metal cutting equipment is sawing and processing metal materials, its metal circular saw blade rotates at a high speed. Normally, when the saw blade touches metal materials, the sound is low and stable. If there is a harsh sound, it must be a problem in a certain part;

1. Incorrect starting position

The so-called starting position refers to the position where the metal circular saw blade touches the cut material. Usually, the saw blade should rotate first, and then touch the cut material, which is more reasonable. But sometimes, due to some parameter setting problems, the saw blade will touch the cut material first, and then rotate, which will cause a larger abnormal noise, It is also a serious damage to the saw blade.

2. The feed speed is too fast

Generally, the feed speed of conventional high-speed circular saw is 4-12mm / s. if it is beyond this range, the impact force of metal circular saw blade on the material to be cut will be accelerated (the faster the speed is, the stronger the impact force will be). In this case, the cutting sound is greater than that of conventional circular saw, because this working mode is a kind of damage to the saw blade itself, So the sound is different; It should be noted that if the feed speed of metal circular saw blade is increased without authorization, the saw blade teeth will be damaged, and in serious cases, the teeth will crack or crack.

3. There are iron chips in Saw Blade Serration

In the cutting process of high-speed circular saw blade, a lot of small iron chips will be produced. If the chips are not removed in time, the iron chips will enter into the equipment and cause the phenomenon of stuck, especially into the serrated parts, which will cause the sharp serrated blade can not directly act on the cut material and cause unconventional sound.

4. The saw blade is not sharp or notched

Any saw blade has its own use time. If it is not maintained in advance, it is easy to cause irreparable failure. We must carry out necessary grinding in advance; When working, check whether the sawtooth position is normal regularly. If there is a gap, stop the machine and replace the saw blade.
