Why does your table saw burning wood?
Burns on your wood after using a table saw are mainly caused by the blade. Specifically, the following reasons:
- Rusty and dirty saw blade
- Curved saw blade
- Dull serrated sawtooth
- Saw the blade in the wrong position
- Unsuitable saw blade
- Material supply speed is slow or uneven
- Wooden pieces warped, flammable
To avoid bad things from happening. Burn marks on wood both unsightly and cause an unpleasant odor. You should find out the cause to fix it. Follow along to know the main reason for table saws that burn wood in the next shares.
Rusty and dirty saw blade
Rusty and dirty saw blades are a common cause of wood-burning table saws. The dirt on the surface of the saw blade will make them work less efficiently.
During cutting wood, the plastic in the wood grain easily adheres to the surface of the saw blade. After a long period of accumulation, they will cause the saw face to become rough or rusty.
The rough saw face increases friction during wood cutting. It is the constant friction between the saw and the wood that causes them to burn the wood.
Not only that, dirty saw blades also make them easier to tarnish. The saw teeth are no longer as sharp as the original, affecting work efficiency.
If you find your table saw blade is working poorly or has dirt. Please clean it up now. You can use some basic cleaners to remove the sap. Clean saw blades won’t burn wood and work more efficiently.
Curved saw blade
Sometimes you don’t notice the saw blade and don’t notice its curvature. It is possible that before the table saw was installed. There was some force acting on it. Or the saw blade is overworked, leading to the high-temperature rise and warping it.
Whatever the cause, a curved saw blade will damage the wood. They will easily knock back the wood during operation. Not only do they burn wood, they also create scratches during kickback.
When the saw blade is bent or warped, replace it immediately. A new saw blade will help you cut wood more efficiently and safely.
Dull serrated sawtooth
An equally important part is the sawtooth. They are the most active ingredients and directly cut the wood. Sharp serrations will cut wood faster and better.
Suppose you see that the saw blade is not dirty but still has burn marks. Check out the cogs.
During use, the saw teeth directly impact the wood surface. The more you use them, the faster they tarnish.
It’s also possible that you used the wrong saw blade for very hardwood. Hardwood will wear down the teeth and make them dull.
You can tell if the serration is dull by the cut and cut time. If the same wood, your saw blade works slower. There are many scratches and rips on the cutting surface. Then that’s when you have to sharpen the saw teeth.
When the teeth are dull, they will constantly rub at a point that cannot move. The sawtooth is too blunt to cut the wood to continue. The constant friction at a site creates an opportunity to burn the wood.
Replace with a new saw blade or re-sharpen your teeth with a file. A sharp set of cogs always works faster.
Saw the blade in the wrong position
Many people often do not care much about the position of the saw blade. But they are very influential. Misaligned table saw blades not only cut your wood the wrong way but also cause burns. They even damage the table saw.
You will cut the cut line. Specifically, when you leave, the table saw blade not parallel to the fence. It will create a skewed line. If you still try to push the board forward, the friction will increase and cause the wood to burn.
Few people will know this, but the height of the saw blade will affect the cutting result.
When the saw blade has different heights, it will create a different contact angle with the wood.
If every element of your chainsaw is perfect but still creates burns. Try raising your saw blade slightly. It can reduce the potential of the table saw to burn wood.
The position of the saw blade is very important. Not only does it affect the accuracy of the cut, but it can also cause burns. Make sure your saw blade is in the correct position before cutting wood.
Unsuitable saw blade
If you pay attention, on different saw blades, there will be different serrations. For example, jagged shapes, like jagged rulers or arranging them, are the different characteristics of table saw blades.
The manufacturer produces each type of sawtooth with its use. Maybe they can all cut ordinary wood. But they will work best in individual cases.
There are also many multi-purpose saw blades available today. They can work in many different jobs. But that’s not always the case. In some cases or with certain types of wood, you must use a special saw blade.
The first is that it can’t work well. If you use the wrong saw blade, it will cause a lot of problems. They cause burns, scrapes and even cracks.
You should consider and choose the most suitable and reasonable saw blades!
Material supply speed is slow or uneven
The person who drives the wood into the table saw also plays a significant role. Needless to say, everything works better when the speed is even. The table saw is such a tool.
When it is working, putting ingredients in slower or faster will cause sudden changes. These sudden changes make the saw blade unable to react. They will often jerk up; in each jerking, there will be strong friction.
It’s like you ignite with two stones. And, of course, burn marks will appear on the wood surface.
In case you put the wood in too slowly, the constant friction at one point will increase the heat. And this is also the cause of the burn marks on the wood.
You should feed the material at a steady and moderate speed to the table saw. It helps the machine to work efficiently and without damaging the saw blade.
Wooden pieces warped, flammable
Warped saw blades cause burns and warping wood pieces too. Warped wood is challenging to handle and control. Often we will have to exert a lot of force on them. This also increases friction and causes burns.
There are also some flammable types of wood. Typical examples are Peach, Cherry, Mahogany, Maple, etc. Some types of wood are flammable when subjected to significant friction. If you must cut these woods, be very careful. Any small mistake can create burns.
How to remove burns?
Black burns and a burnt smell on the wood are not likable things. We should remove them to increase the beauty of the wood.
There are many simple ways to help you remove burns on wood, such as:
- You may sand the burns with sandpaper. This is simple work suitable for removing superficial burns.
- Gently scrape away the layers of burnt wood. If the burns are deep, you should use a wood planer or a razor. You can use them as usual.
However, you can remove burns on wood easily. But repairing the table saw so that there are no burns should be a priority.
There are many different causes of table saw burning wood. However, you can fix it with simple things. Hopefully, you can set them to use the most effective table saw! In this article, we have shared with you why wood burns when using a table saw.
