12 Band Saw Problems and How to Troubleshoot Them

The band saw problems may hinder the success of your projects.  It’s therefore important to keep your saw in top conditions to be on the safe side. A band saw is an essential tool for most carpenters thanks to their versatility and simplicity in use. As a result, regular usage may leave the saw blade and its parts damaged. In most cases, it may give you irregular cuts as opposed to its usual accurate and precise cuts.

Below are some of the solutions for the many questions people ask about band saws problems. Dive in to learn more. Will you?

What Causes Premature Band Saw Blade Breakage? 

  1. Using the Wrong Band Saw Teeth

The blade of a band saw may break if you use an incorrect set of teeth to cut something it’s not intended for. Using a blade whose teeth are too course may lead to their breakage. However, the problem can get averted by using a finer toothed pitch on the surface.

  1. High blade tension

When configuring the stress of the blade, it’s crucial for you to go with the manufacturer’s manual. The manual is clear in setting the perfect blade tension for cutting different materials. Using the manual helps you set the stress to the required PSI for the ideal blade movement. After that, adjust the blade guides for better blade movement.

High tension blades could lead to excessive pressure on the blade. It’s crucial to ensure they remain as per the user manual. You also reduce the risk of the saw blade coming into contact with the wheel flanges.

  1. Overheating Of the Blade

If you use the wrong blade coolant, overheating may occur. As a result, the wood may end up burning. The blade of the saw may also become blunt in the process. Therefore it’s essential for you always to use the correct coolant. Improper fitting of the blade may also cause heat resulting in the wood burn. It’s vital to use the right speed when cutting different materials to prevent the wood from burning. Finally, excessive feed to the blade may cause a wood-burn. Therefore the onus is to you to reduce the feed pressure to ease the wood-burning.

  1. Blunting Of Band Saws Teeth 

The teeth of a band saw may become blunt, especially if you have mounted them in the wrong direction. Blunting may occur when you invert the blades, a situation that can get salvaged by installing them correctly.

Sometimes the blade of a band saw may get blunt from cutting some tough spots such as knots. Also, cutting hard material may dull the band saw blade. You need to inspect the wood for any hard spots properly. This way, you will use the best blade for hard spots preventing the blunting of the edge. Further, should you encounter hard places when cutting, you can increase the feed pressure and feed rate to attack the hard places.

  1. Inaccurate Cuts by Band Saws

You may get uneven cuts by using a blade with damaged teeth set or when using the wrong set of teeth for the wrong material. Sometimes it’s easier to miss a damaged tooth set. However, a proper inspection of the blade from one side of the edge will reveal the problem. Always use the right set of teeth for the right material.

If you are using a blade without proper tension, you may get inaccurate cuts. Loose or worn blade guides could cause abnormal stress. In this case, adjusting the tensioners and blade guides or replacing them if they are worn out is crucial. Also, checking on coolant levels would be recommended should the setting of the proper blade tension fail.

  1. Teeth Breakage on the Band Saw Blades

The band saw teeth can break during the cutting process if you use high speed when feeding the blade. It may also get damaged if the blade pitch size is incorrectly set. Further, if your chip brush is not working, your blade’s teeth may get damaged. You need to replace the worn chip brush to prevent the teeth of the blade from getting damaged further.

  1. Teeth Stripping On a Band Saw Blade

Sometimes a piece of a tooth from a band saw may strip off. In many cases, when you use much pressure to feed the blade, it may get overwhelmed, resulting in breakage. It’s, therefore, essential to reduce the blade speed and feed pressure to avert the blade damage. Always inspect the wood while cutting it to avoid cutting a hard spot on the wood as it could break the teeth.

  1. What Cause Wear At The Back Of A Band Saw Blade?

If your saw blade has insufficient tension, the band saw blade might come into contact with the wheel flange causing wear at the back of the blade. Further, if the blade guides freeze, gets damaged, or becomes worn out, the saw blade may get hurt too. It’s, therefore, important to ensure that the tension is okay always. Also, adjust the stress of the blade and replace worn blade guides to reduce the blade damage.

  1. What Causes Rough Cuts By A Band Saw Blade?

You check for a rough cut by observing the surface of the material you are cutting for defects. You also listen for vibration and chattering during the cutting process. A band saw may produce a rough cut on a substance as a result of using a dull or a damaged blade. If you use high feed pressure or high cutting speeds, the blade may end up giving you rough, inaccurate cuts. Further, always check the tooth pitch and coolant level as they may be the reasons for the rough cut.

You need to replace a blade if it’s worn out to get clean-cut surfaces. Also, increasing the blade speed and feeding pressure may give you cleaner cuts compared to you using slow speeds. Further, if the band saw pitch is the problem, user a finer one and ensure that the coolant level is excellent.

  1. Reasons for a Band Saw Blade Twisting

A band saw blade might twist as a result of various reasons leading to inaccurate cuts. A blade twist can occur when the blade binds to a cut due to excessive feed pressure. In such a case, you should reduce the feed pressure. However, you should also check the tension of the blade and blade guides to ensure they are firmly fastened with the right tension. Check the coolant level to ensure there is no erratic coolant flow.

  1. What Makes A Band Saw Teeth Turn Blue?

The teeth of a band saw may turn blue if you use the incorrect blade to cut material. Further, check the feed and speed of the blade to ensure they are set as per the requirement to prevent damage to the saw blade teeth. The blade coolant is an important component, and its levels should be monitored regularly to prevent the teeth from becoming blue.

  1. What Makes A Band Saw Fail To Start?

A band saw may fail to start if it has a broken power supply, broken power cord, or a defective motor. Therefore it’s essential to make sure all the power supply parts are in good condition. You should also check for a broken power socket by plugging in another working device. If the problem is with the power outlet, check the circuit breaker and reset it. Further, check for defects on the power cord and motor and replace them if they are affected.

Also, check the wiring connection of the saw. If it’s something you can repair, you can go ahead and fix it. Otherwise, it’s always advisable to seek help from technicians to avoid further damage to the saw and also to prevent you from injuring yourself.

Conclusion

Taking care of your band saw should be your priority. It’s an expensive acquisition that deserves proper care for all the work it helps you accomplish. It’s therefore important for you to clean it and store it correctly to ensure it does not cause accidents even in storage. Cleaning and maintaining it ensures all the parts remain rust-free.
