How to avoid wood veneer curling?

When peeling small pieces of wood, it is particularly easy to curl up. Our usual method is to reduce the slope of the blade, which is very effective. However, when the blade surface is too small, when peeling large pieces of wood, we will carry the blade. At this time, we need to give the blade resistance so that the surface of the board is smooth. If the resistance exceeds a certain value, the machine will become unable to pull and lock up. When using large wood, our blade angle slightly retracts, and the machine is very light and fast. The effect of turning thick boards is very obvious, which can reduce back cracks. When using small wood, the contact surface of the drum is small. At this time, we need to stick the blade on it to increase resistance, so the rolling will be lighter.
