Problems such as cracks, excessive wear and tear, breaking of the teeth, or even breakage of the saw blade can often be traced back to incorrect operation of the band saw or improper handling of the saw blade. You can find a few general tips in our article on the correct band saw maintenance. We have also put together a detailed checklist for error analysis for you:

How to Solve Bandsaw Blade Problems
Bandsaw blade does not produce a straight, right-angled cut
- Check whether your saw table is positioned at right angles to the saw band
- Make sure that the belt tension is high enough and that the belt does not sag
- Fix the guide rollers or the machine head correctly
- Check whether the clamping jaws are aligned at right angles to the saw band
- Make sure that the feed table or its rollers run at right angles to the saw band
- Your workpiece should, of course, be straight
- Pay attention to the precision of the settings. Even a slight deviation leads to inaccurate cuts.
Bandsaw blade doesn’t run straight
- Increase your feed a little – your pressure may be too low and give the belt too much play. You can also learn how to correct the coplanar tracking adjustment.
- Check your bandsaw blade for any broken teeth
- Check your tape for inaccurate, misaligned welds
The band wears out too quickly
- Check your band saw for worn and not carefully fixed guide rollers.
- Make sure that your saw blade runs parallel to the head path
- When sawing, reduce your feed pressure a little so that you exert less force on the band. In general, start with little thrust and then slowly increase.
- Examine your saw band for a damaged set
Saw teeth dull too quickly
This problem often occurs with unalloyed saw blades.
- Check that you have chosen a saw blade with the correct tooth spacing
- Check whether the belt speed is suitable for your material and reduce it if necessary
- Check whether you have installed your saw blade the right way
- Try to properly retract the saw band before starting work
The saw teeth on your bandsaw blade break off too often
- Often it is because the teeth are pressed too much into the material for various reasons and the penetration depth is too high
- Check whether you have adjusted your feed speed to the material if necessary increase it a little
- Set the belt speed a little higher to reduce the depth of penetration of the individual teeth
- Check whether the weld seam is offset or not aligned
- Make sure that your saw band is properly tensioned at all times
- A saw band blade with fewer teeth may help you
Cracks appear on the back of the tape
- Make sure that the back of the tape does not run too thickly along the flange
- Check the tape guides for signs of wear
