Quality TCT circular saw blade and is closely related to the quality of processed products. Correct selection of reasonably carbide saw blades for improving product quality, shorten the processing cycle, reducing processing costs is significant. TCT circular saw blade tip comprises an alloy type, a plurality of parameters of the material, diameter, number cutting wheels teeth, the thickness, profile, angle, matrix pore size of these parameters determine the processing capacity of the saw blade and the cutting performance. When selecting TCT circular saw blade sawing according to the type of material, thickness, cutting speed, cutting direction, feeding concrete cutting discs , kerf width requires the correct selection of the blade. Permeability, hardness and rigidity and high speed tool steel with good quenching, less heat distortion, is the ultra-high-strength steel, suitable for the manufacture of high-grade thermoplastic stable thin blade. TCT circular saw blade is the most commonly used wood products processing and cutting tools. The thickness of the blade from the saw blade theoretically we hope the thinner the better, in fact a kerf consumption. The materials and manufacturing process of the blade base alloy saw blade determines the thickness, the thickness is too thin, while the blade is easy to shake the work of cutting the effect of the impact.
