In the wood sawing process, the front mouth of the band saw blade will be prolonged due to the impact friction of the wood. If the band saw blade does not have a rolling bending tendency, the swing of the front mouth of the saw blade will be aggravated, and the saw blade will not run straight and have a bend. The front of the blade is tight, which is beneficial to cutting. This is also an adjustment to the tension before and after.
