The band saw is a 7X12 turn Pro. The blade I'm using is a 6 tooth per inch, standard rake, hard back morse. Cutting AL 2-3 inches square.
A soon as the blade engages, the singing begins. If a vary the feed rate I can modify the sound, and sometimes, eliminate the sound. The cut finish is a little rough. I have also varied the sfm, slower is better. At 260 sfm the sound was loud enough to make my ears ache before I stopped the cut.
It seems to be some form of chatter. What do you think causes it, and more importantly, how do I stop it. I'm sure it's not good for the blade (and my ears).
