For an optimum cutting quality and a long service life of the saw blade, it is absolutely necessary that the tension in the saw blade is tested repeatedly and, if necessary, rerolled. Unfortunately, this need is not considered and the band saws often have a reputation of not cutting precisely. The tension is tested for all saw bands that we receive for sharpening. Since the saw blades run stress-free due to the design of our log band saw, it is possible to re-stellite the saw blades several times. This of course considerably reduces the on-going blade costs.
