On band saw blades cutting teeth can wear, break or crack. There may be three main reasons for this unexpected problem with the band saw blade.

  • human error
  • Machine caused error
  • The cut material and the selected blade are incompatible

It is very important for the user to know the possible causes of malfunctions so that they can take effective measures.

Premature Saw Blade Wear Is Not Normal

Bandsaw It is natural for teeth to wear and crack over time due to use. Because, like every material, the saw blade also has a lifespan. However, it is necessary to distinguish between this normal wear and premature severe wear. There are many factors that cause unnaturally rapid wear.
When choosing parameters such as cutting speed, cutting performance and feed rate, the size and surface structure of the material should be taken into consideration. Especially when cutting sanded and extremely hard materials, incorrect parameter settings will harm the lifespan of the blade.

Excessive tension that may occur during incorrect placement of the material may also cause micro cracks and breaks in the blade. Necessary cooling fluids must be used to prevent premature wear of the blade.
In addition, not changing the brush on time or adjusting it incorrectly, which is used to clean the burrs and waste from the saw band, reduces the lifespan of the blade.

Prevent Saw Teeth from Cracking and Breaking

Tooth breakage is not a consequence of the saw's natural lifespan. This result usually occurs when the teeth are overloaded. Reasons such as excessively low cutting speed at high feed rate and incorrect selection of tooth pitch (pitch) of the blade may cause tooth breakage.

Care should be taken to fix the material to be cut as best as possible. Movement of the material during the cutting process can also cause teeth to crack and break. It is necessary to pay special attention to this, especially when cutting layered or bundled materials. When cutting very soft materials, care should be taken to ensure that the oil content in the coolant is high.

Guides too tight, tension too high, feed rate too slow, coolant flow too low, improper coolant mixture, guide arms misaligned, feed pressure too high, wheels damaged or dirty, speed too high Attention should also be paid to issues such as the machine's operating time being too long, and the wheel bearings being damaged.
