Most of the new saw blades fail because the staff has not adjusted the tension of the saw blade properly. The tension of the metal band saw blade is too tight when sawing, and the load is too large, which can easily lead to band breaking or tooth cracking. If the workpiece is found to be cut oblique when sawing, it indicates that the band saw blade has been distorted. When the metal band saw blade is distorted, it will be blocked by the tilt and lead to fracture or tooth collapse. At this time, the clamping of the band saw blade should be checked whether it is in place; Secondly in the replacement of the new band saw blade, should be appropriate to “run in”, the sawtooth of the new saw blade and many burrs, will increase the cutting resistance, if not run in instant high-speed sawing will cause damage to the metal band saw blade. The running in of the metal band saw blade should adjust the slow feed, and give the band saw blade enough lubrication. The sawtooth of the new saw blade should be smoothed and then sawed at a normal uniform speed.
According to the past experience, some customers will respond, I used the bimetal band saw blade bought from you to cut the new workpiece, how come everything is broken or toothed? Because usually when picking tooth, professionals will be according to your cutting workpiece size and hardness of selecting pitch, to determine the metal band saw blade, but this does not mean that this type of saw blade can cut any other size and hardness of different artifacts, if you are late change of workpiece size is too small, it must be replaced small pitch band saw blade, If the hardness of the new workpiece is too high, the hard alloy band saw blade should be used. It is recommended that you consult a professional before changing different pieces to ask if the band saw blade you are currently using can cut the piece you are replacing.
