What are the width requirements for band saw blades?

There are two kinds of tension devices for the saw blade of the band saw machine: spring and thallium (heavy hammer). This machine is a spring device. The base tension should be determined according to the width, thickness and speed of the saw blade. Usually, the finger is used to press the saw blade, and the proper tension is determined according to the left and right curvature of the saw blade. In general, when the saw blade is pressed by hand, the curvature of the saw blade should be between 3.2 and 6.4 mm.
The width of the saw blade of the band saw machine should be compatible with the width of the wheel surface of the saw wheel, and cannot be too wide beyond the wheel surface.
The saw blade is clamped in the middle of the saw clamp. The bottom of the saw tooth should be in line with the outer edge of the saw clamp. The saw blade cannot be clamped too tightly. It should be able to slide in the middle of the saw clamp. The back of the saw blade is about 0.8 mm away from the pulley. If the saw blade has already contacted the pulley when it is idling, it means that the saw blade is behind, or the pulley is in front, or the proper tension of the saw blade disappears. Adjust the upper saw wheel or pulley, or remove the saw blade. Line inspection, rolling and trimming.
When replacing the saw blade of the band saw machine, first open the upper and lower guard doors, loosen the fixing screws of the slide plate, turn the lifting hand wheel to lower the upper saw wheel, loose the saw blade, remove the old saw blade, and put the repaired saw blade on the upper and lower saw wheels. The sharp angle direction of the saw tooth is downward, do not turn up, and then turn the lifting hand wheel to raise the upper saw wheel and tension the saw blade. Then turn the upper saw wheel by hand to see if the saw teeth are all exposed on the outer side of the saw wheel rim. If it is not exposed, the upper saw wheel should be adjusted until the saw teeth are exposed to the rim, and the edges of the upper and lower saw wheels move smoothly, and Up to the work surface.
