burned pine to cut

[frankorona]

Hi Steve:
I have a question, usually I have always worked with MDF veneer in different sizes and have not had any problems.
My problem starts when I use solid wood in this case pine.
I am working with thickness measures 3 / 4 "and 1" and found a way to go without me deform the part.
But in some cases the wood starts to burn, I have reviewed the calibration of the blade and well.
What's my problem?
Does the wood has lots of resin and friction burns?
My blade no longer has enough edge and cause me problems?
How long does the edge of the blade with this type of wood?
Is it wood? I see that fractures easily as it has many veins and makes it brittle.
Thanks in advance for your response and attention to this mail.

If you are using yellow pine it has a lot of resin and burns easily.

Pine does have a lot of grain and does break easily.  If you can find it try poplar, you will find it does not burn as easily and is more stable with tighter grain.

can't always do a lot of it.
- if this happens to me I try a bigger blade, a #5, #7 or higher.
- I look if blades are still sharp (don't push to hard on a dull blade)
- I slow down the speed ( Don't know if your machine can do this)
- I use tape on the bottom and top, this "lubricates" a bit.
and then you still will have some burned spots here and there, at least I have.
