Troubleshooting for Band Saw Usage
The most common causes of trouble while cutting with band saw blades is wrong choice of band saw blade type, dimensions of blade or wrong tooth pitch for particular material. The second most common problem is wrong performance of cutting conditions and usage of insufficiently set or dull band saw blade.
In the below tab you can find most common problems and their possible solution.
| Most common problem | Probable reason | Solution |
|---|---|---|
| Broken/ fissured blade | Wrong tooth pitch | Choose a blade with tooth pitch so that 3-5 teeth are in cut |
| Overstressing of blade | Lower the blade straightness between circling wheels | |
| Feed is too high | Lower down-force of material on the blade | |
| Teeth are in contact with material before cutting | Adjust allowance between blade/material to minimum 10mm before cutting | |
| Diameter of guiding wheels is too small | Use a thinner blade | |
| Side press on band saw | Adjust manually | |
| Blade friction against carrier wheels | Adjust parallelity of wheels | |
| Undercutting | High feed | Lower the feed speed |
| Insufficient blade straightness | Straighten the blade | |
| Damaged top tooth line | Use a blade with harder teeth (hardened) | |
| Big allowance between guiding wheels and blade | Lower the guiding wheels | |
| Big distance between guidance and material | Adjust distance from guidance | |
| Rough cut | High feed | Adjust cutting conditions |
| Wrong tooth pitch | Use correct tooth pitch | |
| Blunting of blade | Cutting with tooth backs | Turn over the band saw blade |
| High cutting speed | Lower the cutting speed | |
| Tooth breaking off | High pressure on blade | Lower the feed speed |
| Wrong choice of tooth pitch | Use correct tooth pitch | |
| Cutting with tooth backs | Turn over the band saw blade | |
| Dirt in cutting material | Do not cut in places where dirt occurs (stones, metals etc.) | |
| Twisting of blade | Blade stuck in cut | Lower the feed speed |
| Free guiding of blade | Adjust the blade guiding |
