A dull blade will make it hard to cut quickly, and the slower the feed rate of the saw, the more friction against the wood and the greater the likelihood of scorch marks. Pushing the stock through the saw too slowly is a common cause of saw blade burn. Sometimes a blade that feels dull might only be dirty.
If you see burn marks on the cut edges of wood after you cut them with your table saw, it is because excessive heat from the saw blade is scorching the stock as it passes through the wood. Measure between the blade and the fence at both front and back of the blade and if the measurements aren’t exactly the same, check your saw use-and-care manual and adjust the blade alignment so it is correct. If you make the proper adjustments to your saw before you begin the project, you’ll decrease the chances that you’ll have to deal with saw blade burns.
Issues like the all-too-common problem of the circular saw blades burning the wood you are working on. Another reason why your circular saw is that the guide fence and saw blade are not aligned perfectly. Dull blades obviously make it much harder to cut wood quickly and as we’ve already discussed a slower feed rate increases the chances of the wood getting burned.
For our final section, we will go over several mechanical reasons your skill saw could be smoking. If the motor of your skill saw has failed, then you’ll probably want to get a new saw. If you’re using a very long, low voltage extension cord while operating your skill saw, then you could be losing out on power and subsequently stressing your saw.
If you see burn marks on your wood after you’ve used your table saw to cut it, it is because there is too much heat between the blade and the wood. If the table saw still burns wood after you clean the blade, it could be that the blade is too dull. A dull blade will cause excess heat to build up between the saw blade and the wood.
So when you are feeding the wood at a slow pace, the blade now has more time to rub against the side of the wood and burn. So what happens is the dirt heats up very quickly and subsequently causes the wood to heat up faster than if the wood was just hitting the blade. A dull blade, a fast feed rate, wrong blade and dirty saw blades make up 90% of the reason wood burns, but that still leaves the other 10%. Well, the other 10% are not that common, but if the above three items do not take care of your problems, you can also check these following items to pinpoint why you are burning wood.
