A misaligned band saw wheel will move the band saw blade during the cut giving you a production that will not be acceptable for your project. However, you will be able to fix your band saw and once again realize accurate cuts with a little maintenance affecting the alignment.
Inspecting the cut itself is the most common way to figure out if your band saw is cutting incorrectly. Operators have to make sure that they double-check each cut so that they will know if the piece is still usable or not. Your band saw wheel will probably need to be cleaned, oiled or replaced if the piece varies in size at different points.You will need to also clean or oil your wheels if your band saw wheels are dirty. You will know if it’s dirty when you hear sounds emanating from the machine as it runs.
Inspecting the cut products themselves is the most common way to figure out if your band saw is cutting incorrectly. Operators have to make sure that they double-check each product so that they will know if the piece is still usable or not. Your band saw wheel will probably need to be cleaned, oiled or replaced if the piece varies in size at different points.You will need to also clean or oil your wheels if your band saw wheels are dirty. You will know if it’s dirty when you hear a strange noise as you run your band saw machine.
It is important to look after your safety as well. Wear safety goggles and gloves to avoid injury as you will be removing both a band saw blade and small parts. It is important to make sure that the saw is disconnected from any electricity so that the machine is not accidentally turned on while you are doing your maintenance check.
You must open the band saw’s doors to get access to the band saw blade inside once the power has been disconnected. Then, carefully tilt the band saw so that you are able to slip your ruler or straight edge across both the lower and top wheels of your device, making sure that it is long enough to lay across both wheels at the same time. Take note that certain models may need to have the table completely disconnected from the band saw for this maintenance step.
Check the alignment between both the top and bottom band saw wheels and the installed blade to make sure that the band saw blade is installed correctly. You need to double check your measurements to make sure that your data is correct. It is important that there is a band saw blade during this process, as the measurements will be off because there is no blade tension available.
If there is any misalignment between the wheels and the band saw blade, remove the band saw blade and the misaligned wheel once you know which wheel is misaligned.
Operators should make sure that they add and attach the right amount of shims behind the wheel to make sure that both the top and bottom of the wheels are aligned correctly. Double-check your work, then re-attach the wheel to the band saw.
Reinstall the band saw blade and check the measurements again after the wheel has been attached. Your work is done if the measurements are correct. If they are not, you will need to repeat the process until it is correct.
