Alloy circular saw blade is selected for different cutting materials tooth type and angle

The number of teeth, generally speaking, the more teeth, the more cutting edge in unit time, the better the cutting performance, but the number of cutting teeth need more carbide quantity, the price of the saw blade is high, but the sawtooth is too dense, the chip tolerance between the teeth becomes small, easy to cause the saw blade fever; In addition, too many saw teeth, when the feed is not properly matched, the cutting amount of each tooth is very small, will intensify the friction between the edge and the workpiece, affecting the service life of the blade. Usually the tooth spacing in 15-25mm, should choose a reasonable number of teeth according to the sawing material.

Any alloy circular saw blade can cut different materials, but the effect or life is necessarily fatal quality effect. Alloy circular saw blade generally has ordinary tooth type, and many pieces of serrated and humpbacked tooth type. Common tooth type is for dense tooth or precision cutting, and aluminum profiles. Multi - blade saw is for thinning teeth, slotting or feeding and cutting feed fast enough products. Humpback teeth are suitable for hard cutting or metal cutting, and have the function of cutting depth. Any type of tooth design considers the length and thickness of the alloy according to the pitch, diameter and cutting force. The width and length of the heat sink and the Angle are also very important. The arc of the cutter back groove is directly related to the pitch of the tooth. The Angle of the tooth back must consider the cutting impact force and chip removal. Of course, the matrix thickness should be reduced by 1 or 0.8 coefficient according to the blade width, so that the matrix teeth can have strong impact force.
