Band saws are usually used for sawing large wood. If the sawn wood is bent, it will cause a lot of losses. There are many factors for this situation. Generally, the saw blade of the woodworking band saw has a problem. , Let’s take a look at several reasons for saw road bending.
1. Reasons for saw blade:
The tensioning device of the band saw is out of order, the hammer is too light, and the saw blade is not properly tensioned, so it is easy to bend when sawing wood. The same can happen if the saw tooth shape is not correct or the tooth chamber is too small, the saw blade has too many joints, and the saw blade is narrow and deviated. Correct the tooth shape, enlarge the saw path, and try to use a saw blade with fewer joints.
2. Reasons for operation:
The saw card of the band saw is too loose or has deviation; the feeding speed during sawing is too fast, there is sawdust or resin on the saw wheel or saw blade, or the saw teeth are blunt, which may cause the sawed wood to bend.
Maintain a stable feed when sawing, slow down when there are knots, and remove the sawdust on the saw wheel or saw blade in time, which can completely avoid the bending of the saw.
