Are you using a coolant? Using lubrication will help the prevent the bandsaw teeth from stripping.

Ensure you set the speed rate in the range that the machine manufacturer recommends. Are you using the recommended teeth size (Teeth Per inch) TPI for the material you are cutting?

Also, ensure a properly working chip brush. Lastly, inspect the material for any hard spots.

Inaccurate Cut

The bandsaw blades may perform an inaccurate cut as a result of an improper break-in.

Also, you can check if the guide arms are out of alignment or far apart. The rollers need monitoring to make sure it is not damaged. Feed rate and speed may also affect the performance of the blade cut.

The blade is probably dull if the cutting does not follow the line you are cutting despite checking all the parts.

Premature dulling of teeth

The possible improper procedure of break-in may be one of the causes of premature dulling bandsaw teeth. Check the coolant concentration and flow.

The feed rate and bandsaw machine speed must be at the normal range. Inspect if the teeth are in proper pitch and not pointing in the wrong direction. Fix the bandsaw blade if mounted backward. There may be hard spots in the materials.

Breakage of Band

The primary cause of band breakage is due to high tension so try to decrease the feed pressure. Set the guides not too far apart. Try to use thinner wheels if the diameter of the wheels is small. Perfectly squared clamp along with well-welded butt ensures prevention of bandsaw breakage.


Chip Welding

If the flow of coolant is insufficient, then it may provide the wrong concentration. Monitor the rates such as the pressure and speed, make sure it’s not too high. Moreover, maybe the size of the tooth is too small for what you are cutting. Again, ensure the chip brush is not malfunctioning.

Blades’ Breakage Prevention

Indeed, the best technique is breaking-in the blade to prevent new bandsaw blades from early breakage. This technique is simply reducing the feed rate/force control to approximately 20% to 50% of the normal cutting rate and gradually increasing the feed pressure to 100 percent.
