During the use of band saw blades, there will be many problems. Among them, the fracture or crack of the saw band is the most common problem. Generally, the fractures that occur are parallel to the weld, and the longitudinal fracture of the saw band has you encountered ? The saw band has deep and deep scratches in the longitudinal direction. In severe cases, the saw band is split into two to three narrow strips. It is rare that the fracture is as smooth as a knife cut. But what is the advantage of this phenomenon?
1. The guide block or guide arm bearing has hard spots on the corresponding scratches.
2. A hard object is squeezed into the corresponding point of the saw wheel rim and the scratch on the saw band, and the surface of the saw band is repeatedly affected by the hard point.
3. The distance between the saw wheel and the guide arm is small, and the increase of the twisting force causes the saw band to tear under the action of frequent twisting.
