Why Does My Table Saw Burn Wood

After you have used a table saw to cut the wood, and you see burn marks on it after you have done the work, that means there is a lot of heat between the wood piece and the table.

The heat is generated from the friction, which is created when the saw’s blade cuts through the wood.

A wide range of problems causes this friction. These kinds of issues can either stem from machine error or user error.

Even though most of the times, people do not take wood burns seriously, but they can indicate some serious problems which the table saw might have.

Following these solutions would help you to cut your wood safely and accurately. So without any future ado, let’s start with our list right away.

1. Using An Unclean Blade

This is one of the most common reason for wood burns.

Go and inspect whether the blade’s surface is clean or not.

As you work, saw blades are often coated in resin and pitch as they cut through the wood. Building up of these elements not only makes the saw blade dirty, but it can also be the case of the burn marks on the wood.

You can clean the saw blade with specialized cleaning solutions, but you should be careful while handling it.

2. Using A Blunt Blade

If the blade of your table saw is not properly sharpened, then it would inevitably cause more heat buildup when you are working on the wood.

You should check for rounded, missing, or chipped blade teeth.

In case it is a high-quality blade, then you can take it to a service center and get it sharpened.

However, if it is a standard quality or inferior quality blade, then you should get it replaced. 

3. Using The Wrong Blade

You can buy all-purpose blades for tackling typical jobs. However, if you have any special work requirements, then you should go for a particular saw blade.

The shape of the individual teeth, space between them, number of teeth, and other such factors determine the amount of heat which will get generated.

Using the wrong blade for the wrong task might result in severe burn marks.

4. Table Saw Out of Alignment

Wood burns are also caused when your table saw does not have alignment.

Even if any part of the device is out of alignment, it would also make it difficult for you to work.

Alignment issues can occur with the blade, miter slot, splitter, and the fence. These alignment issues can also result in severe safety hazards.

5. Less Powerful Table Saw

In the market, you would come across table saws of different brands and styles. Therefore, some table saws are always going to be more powerful and effective than others.
