The pressing mound is used at the tensioning device of the woodworking band saw. If the mound is too heavy or too light, it will affect the band saw. Too heavy will cause the circularity to disappear, resulting in the saw blade not being completely attached to the saw wheel, and it is easy to cause running. Bars or drop bars. If the pressure tuft is too light, the tension of the saw blade will not be achieved, and the saw blade will easily run off.
Then the weight of the mound is appropriate. Don't blindly increase the mound when you run a bend when sawing. This will increase the tension of the saw blade, and it will be impacted and rubbed when sawing wood, which will easily cause the saw blade to crack. When the weight of the mound is appropriate, the mound can move up and down with the sawing of the wood. If the mound does not move, the mound is too heavy.
We can also press the mound with our hands. If the elasticity is large, the weight of the mound is too light, and if the elasticity is small, the mound is too heavy. Light weight will cause the saw blade to swing from side to side or back and forth; while too heavy weight will cause the saw blade to break easily, so the weight should be kept moderate.
