Is the domestic woodworking saw blade manufacturers increasing. But the quality can not be compared to foreign. Under normal circumstances, sawing particleboard, dense plate should be selected around the tooth, saw the paste panel, fire board generally choose flat ladder teeth (flat teeth, trapezoidal tooth combination). Saw blade diameter according to different circular saw machine models to Ф300-350mm majority, saw blade thickness and diameter. Ф250-300mm thickness of 3.2mm, Ф350mm more than 3.5mm.
Computer saw saw cutting rate because of the large, with carbide saw blade diameter and thickness are relatively large, diameter 350-450mm or so, the thickness of 4.0-4.8mm between the majority of the use of flat ladder teeth to reduce the collapse of edge , Saw marks.
Sawing solid wood alloy saw blade is usually combined with the tooth into the teeth, due to the combination of large anterior horn, can be sharp to the wood fiber tissue interception, incision and smooth. For the slot to keep the bottom flat, it is necessary to use flat tooth profile or with left and right combination of teeth.
Hardness is not enough, then it will be easily deformed in the course of the use will not hold. Hardness in the stress and thermal deformation under more easily broken is also a fact, in general, the higher the hardness of the material, the bending strength and impact toughness is lower. But the alloy saw blade for more woodworking, but also not to break the steel that strength it.
In use, the saw blade adjusts the rotation, which transfers both the cutting force and the workability. Excellent blade not only has a static geometry and accuracy, more importantly, its dynamic characteristics. When the saw blade continuous cutting, the alloy sawtooth cutting heat generated by conduction to the substrate, the substrate temperature, high-quality matrix in this case can maintain the accuracy of the statement, and poor quality of the saw blade will occur Matrix warping, affecting the cutting accuracy.
Shape processing accuracy, although necessary, but the average of the saw material, sawing processing heat treatment process may cause the saw body in the heat and high-speed operation is not chaos.
