Why Does My Makita Circular Saw Burn The Wood
When working with a circular saw, it can be frustrating to see that the wood you are cutting ends up burned. This discoloration and burning can not only ruin the appearance of your project but also weaken the structural integrity of the wood.
The burning of wood while using a Makita circular saw can be attributed to several factors. One of the main reasons is improper blade selection. If you are using a blade with a high tooth count or improper tooth geometry for the type of wood you are cutting, it can generate excessive heat, causing the wood to burn.
Another reason for wood burning is a dull or dirty blade. A dull blade will require more effort to cut through the wood, generating more friction and heat. Similarly, a dirty blade can accumulate resin, pitch, and sawdust, which can also contribute to burning.
Additionally, using excessive speed or force while cutting can cause the blade to rub against the wood, generating heat and resulting in burns. It is important to choose the appropriate cutting speed and apply consistent, even pressure to avoid these issues.
To prevent wood burning when using a Makita circular saw, make sure to select the correct blade for the type of wood you are cutting, maintain a sharp and clean blade, and use the appropriate cutting speed and pressure. These precautions will help you achieve clean, precise cuts without any burning or discoloration.
Remember: a well-maintained circular saw and proper cutting technique are key to avoiding wood burning and achieving professional-quality results!
