(6) The selection of tooth shape commonly used teeth are left and right teeth (alternate teeth), flat teeth, ladder flat teeth (high and low teeth), inverted trapezoidal teeth (inverted conical teeth), dovetail teeth (hump teeth), and rarely seen industrial grade three left and right, left and right flat teeth, etc.
The most widely used teeth, cutting speed, relatively simple repair. Suitable for cutting and cross sawing all kinds of soft and hard wood profiles and density board, multilayer board, particleboard, etc. The left and right teeth with anti-rebound protection teeth are dovetail teeth, which are suitable for longitudinal cutting of various boards with tree nodes. Left and right toothed saw blades with negative front Angle are usually used for face sawing due to their sharp serrated edges and good cutting quality.
This flat teeth curf coarser, cutting speed is slow, grinding is the most simple. Mainly used for common wood sawing, low cost, mostly used for aluminum blades with small diameters, to keep cutting less adhesion, or used for grooving saw blades to keep groove bottom level.
3. Plain teeth ladder is a combination of trapezoidal teeth and flat teeth. It is complicated to repair and grind them. The process of sawing can reduce the cracking of veneers. Aluminum saw blades with a large number of flat teeth are also used to prevent adhesion.
4. Inverted ladder teeth are often used in cutting board saw bottom groove saw blade. When cutting double-faced wood-based board, the groove saw can adjust the thickness to complete the groove processing of the bottom surface, and the main saw can finish the cutting processing of the plate to prevent the phenomenon of edge breaking.
