Reason Analysis of Saw Bias of Bi-metal Band Saw Blade

　　A variety of failures always occur when the saw blade is run on a sawing bed, where sawing is a common failure.

　　The so-called saw-saw refers to the inclination of the saw blade during the cutting of the material. In general, the more common saws are brazed on the outside. This is mainly because the band saw blade is not clamped during installation, the saw blade does not enter the vertical state, and the more laborious side is always better. It is vulnerable to stress and it is subject to damage and sawing. Of course, the saw-saw generation also involves the operator's technology, the adjustment of the sawing machine, and the like. We will analyze the causes of saw-saw.

　　First of all, it is the reason for sawing. Sawing machine leaks due to the hydraulic system or the reason that the speed control valve is out of control causes the instability of the sawing machine operation. Unstable saw operation, the band saw blade will tend to tilt, tilting the saw oblique fault is easy to produce. In addition, if the distance between the left and right guides of the sawing machine is too large, or the tension given to the band saw blade is insufficient, resulting in the wear of the guide block or the improper setting of the saw blade, the sawing quality will be directly affected, and the saw blade will eventually be derived. Oblique problem.

　　Second, sawing caused by poor operator operations. According to the survey statistics, most of the reasons for seesaw are poor operation. For example, after the saw blade is installed, it does not do any inspection and adjustment, and it allows the saw blade to perform high-speed cutting movements. Second, after the saw blade has been operating for a long period of time, it does not give a rest. It does not clean the impurities left on the band saw blade. As a result, the saw blade may be prematurely simmered during the cutting process, or the saw teeth may be broken, so that saw-saw faults may occur. .

　　Finally, there are several undesirable factors that can cause saw-saw. For example, the guide block does not clamp the saw blade, or the plane of the guide block has worn out. Therefore, if the saw-saw problem to be avoided should be noticed, measure the vertical accuracy of the saw blade and clamp the guide block. At the beginning of the sawing, it is necessary to slowly cut the workpiece and then speed it up so that it can be sawed more smoothly.
