The commonly used tooth shapes of alloy saw blades include left and right teeth (alternating teeth), flat teeth, trapezoidal 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 left and right flat teeth and so on.
1. The left and right teeth are the most widely used, the cutting speed is fast, and the grinding is relatively simple. It is suitable for cutting and cross sawing various soft and hard solid wood profiles and MDF, multi-layer boards, particle boards, etc. The left and right teeth equipped with anti-rebound force protection teeth are dovetail teeth, which are suitable for longitudinally cutting various boards with tree knots; the left and right teeth saw blades with negative rake angle are usually used for sticking due to sharp teeth and good sawing quality. Sawing of panels.
2. The flat tooth saw edge is rough, the cutting speed is slow, and the grinding is the easiest. It is mainly used for sawing of common wood, and the cost is low. It is mostly used for aluminum saw blades with smaller diameters to reduce adhesion during cutting, or for grooving saw blades to keep the bottom of the groove flat.
3. Ladder flat tooth is a combination of trapezoidal tooth and flat tooth. Grinding is more complicated. When sawing, it can reduce the phenomenon of veneer cracking. It is suitable for sawing of various single and double veneer wood-based panels and fireproof panels. In order to prevent sticking of aluminum saw blades, saw blades with a large number of flat teeth are often used.
4. Inverted ladder teeth are often 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, so that the Prevent the saw edge from chipping.
To sum up, the left and right teeth should be selected for sawing solid wood, particleboard and medium density board, which can cut the wood fiber structure sharply and make the incision smooth; in order to keep the groove bottom flat, use the flat tooth profile or the left and right flat teeth. Combination 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 in the computer sizing saw are relatively large, with a diameter of about 350-450mm and a thickness of 4.0-4.8 Between mm, most of the flat teeth are used to reduce chipping and saw marks.
