Selection of number of saw blade teeth

The number of teeth of the sawtooth, generally speaking, the more the number of teeth, the more cutting edges per unit time, the better the cutting performance, but the more cutting teeth need to use more cemented carbide, the price of the saw blade is high, but the sawtooth is too dense , the amount of chips between the teeth becomes smaller, which will easily cause the saw blade to heat up; in addition, if there are too many saw teeth, if the feed rate is not matched properly, the cutting amount of each tooth will be very small, which will increase the friction between the cutting edge and the workpiece, and affect the service life of the blade. . Usually the tooth spacing is 15-25mm, and a reasonable number of teeth should be selected according to the material to be sawed.
