The commonly used tooth shapes of alloy saw blades include left and right teeth (alternating teeth), flat teeth, ladder flat teeth (high and low teeth), inverted trapezoidal teeth (inverted conical teeth), dovetail teeth (hump teeth), and rare industrial grade three left and one right, left and right flat teeth, etc.
1. The left and right teeth are widely used, with fast cutting speed and relatively simple grinding. It is suitable for cutting and cross sawing all kinds of soft and hard solid wood profiles, MDF, multilayer board, particleboard, etc. The left and right teeth equipped with anti-rebound protection teeth are dovetail teeth, which are suitable for longitudinal cutting all kinds of plates with tree knots; The left and right tooth saw blades with negative rake angle are usually used for panel sawing because of their sharp teeth and good sawing quality.
2. The flat tooth is rough, the cutting speed is slow, and the grinding is the simplest. It is mainly used for sawing ordinary wood with low cost. It is mostly used for aluminum saw blade with small diameter to reduce adhesion during cutting, or for slotting saw blade to keep the groove bottom flat.
3. The ladder flat tooth is a combination of trapezoidal teeth and flat teeth. The grinding is complex. During sawing, it can reduce the cracking of veneer. It is suitable for sawing all kinds of single and double veneer wood-based panels and fireproof panels. Aluminum saw blade in order to prevent adhesion, the saw blade with more teeth of ladder flat teeth is also used.
4. The inverted ladder tooth is often used in the bottom slot saw blade of the panel saw. When sawing the wood-based panel with double veneers, the thickness of the slot saw is adjusted to complete the slotting of the bottom surface, and then the main saw completes the sawing of the panel, so as to prevent edge collapse at the saw mouth.
To sum up, the left and right teeth shall be selected for sawing solid wood, particleboard and medium density board, which can cut the wood fiber tissue sharply and make the incision smooth; In order to keep the groove bottom flat, use flat tooth profile or left and right flat combined teeth; Ladder flat teeth are generally selected for sawing veneer and fireproof board. Due to the large sawing rate, the diameter and thickness of the alloy saw blade used for computer cutting saw are relatively large, with a diameter of about 350-450mm and a thickness of 4.0-4.8mm. Ladder flat teeth are mostly used to reduce edge collapse and saw marks.
