How to choose carbide saw blade saw blade teeth?

Carbide saw bladeis the most commonly used cutting wood products processing, the quality of the carbide saw blade has close relationship with the quality of processed products. Selection of correct reasonably carbide saw blade for improving product quality, shorten the processing cycle, reduce the processing cost is of great importance. Carbide saw blade containing alloy tool bit types, substrate material, diameter, number of teeth, thickness, tooth shape, Angle, aperture, and many other parameters, these parameters determine the processing capability of saw blade and cutting performance. Choosing saw blade should be according to the types of cutting material, thickness and the direction of the cutting speed, cutting, sawing feeding speed, road width need to correct selection of saw blade.
(a) selection of cemented carbide
The types of commonly used cemented carbide tungsten cobalt (code YG) titanium, tungsten classes (code YT). As a result of the tungsten cobalt class carbide has good impact resistance, more widely used in wood processing industry. Model is commonly used in wood processing of YG8 - YG15, YG behind the digital representation of the percentage of cobalt content, the cobalt content increased, the alloy impact toughness and bending strength increased, but the hardness and wear resistance has declined, according to the actual situation to choose them.
The choice of the number of teeth
Jagged teeth, generally speaking, the more the number of cutting edge in unit time, the more the better the performance of cutting, the cutting teeth need carbide quantity more, the price of the saw blade is high, but saw a cipher, tooth chip capacitors between the quantity is small, easy to cause the saw blade fever; Also saw too much, when feeding with improper words, each tooth cutting quantity are very few, will sharpen the edge with workpiece friction, affect the service life of blade. Usually insert spacing in 15 to 25 mm, should choose the number of teeth on the reasonable according to cutting material.
