Selection Of Tooth Shape Of Carbide Saw Blade

Carbide saw blades are thin round cutters made of carbide for cutting solid materials (such as wood products, metal materials, etc.). For cutting different materials, the selected saw blade tooth profile is also different.

There are many kinds of tooth shapes of carbide saw blades, including flat teeth, trapezoidal flat teeth (high and low teeth), left and right teeth (alternate teeth), dovetail teeth (hump teeth), inverted trapezoidal teeth (inverted conical teeth) and not. Common industrial grade three left and one right, left and right flat teeth and so on. So, how to choose the right tooth shape of carbide saw blade?

1. Flat tooth - flat tooth saw rougher, lower cost, slower cutting speed, and the easiest grinding. It is mainly used for sawing ordinary wood, which can reduce adhesion during cutting, and can also be used for slotting saw blades. to keep the bottom of the groove flat.

2. Trapezoidal teeth - a combination of trapezoidal teeth and flat teeth, the grinding is more complicated, and the cracking of the veneer can be reduced during sawing. It is suitable for sawing of various single and double veneer wood-based panels and fireproof panels.

3. Left and right teeth - the most widely used, fast cutting speed, relatively simple grinding, suitable for cutting and transverse sawing of various soft and hard solid wood profiles and MDF, multi-layer boards, particle boards, etc.

4. Dovetail teeth - left and right teeth equipped with anti-rebound force protection teeth, suitable for longitudinal cutting of various boards with tree knots; left and right teeth saw blades with negative rake angles are usually used due to sharp teeth and good sawing quality. For sawing of veneer.

5. Inverted trapezoidal teeth - commonly used in the bottom groove saw blade of panel saw. When sawing double-veneer wood-based panels, the groove saw adjusts the thickness to complete the grooving process of the bottom surface, and then the main saw completes the sawing process of the board. , in order to prevent the edge of the saw edge from chipping.
