the common knowledge for cemented carbide saw blades

Cemented carbide saw blade tooth shape, Angle, teeth, blade thickness, type, diameter, carbide saw blade, most of the parameters, these parameters determine the processing capability of saw blade and cutting performance. Blade according to the need to choose correct choice saw blade parameters.

Tooth shape commonly used with flat teeth on tooth profile, Dou, trapezoidal tooth, inverted trapezoidal tooth, etc. Flat teeth used most widely, mainly used for ordinary wood sawing, this kind of tooth shape is more simple, curf coarser, flat teeth of grooving process operation can make the bottom of the channel is flat and level. Dou tooth cutting curf quality is good, suitable for cutting all kinds of man-made board, laminated board. Trapezoidal tooth is suitable for cutting veneers, fire prevention board, can obtain high cutting quality. Inverted trapezoidal tooth often used for bottom groove saw blade.

The Angle of the sawtooth is sawtooth in cutting position. The Angle of the sawtooth affecting the cutting performance effect. The largest is the former influence on cutting Angle gamma, wedge Angle after alpha, beta. Former Angle gamma is jagged cut Angle, the larger the rake Angle cutting the brisk, anterior horn usually between 10 to 15 °. Angle is serrated and machined surface of the Angle between the, its role is to prevent the sawtooth and machined surface friction, the smaller the Angle, the greater the friction, after processing of the product is more bright and clean. Carbide saw blade Angle after the general values of 15 °. Wedge Angle is led by former Angle and back Angle derived. Wedge but not too small, it plays a stay according to the strength of the tooth, the action of heat resistance, durability. Wedge Angle between before and after the Angle alpha, beta is equal to the sum of 90 °.

The number of teeth on the blade In general, the more the number of cutting edge in unit time, the more the better cutting performance, cutting teeth but need more carbide quantity, the price of the saw blade is high, but saw a cipher, tooth chip capacitors between the quantity is small, easy to cause 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.

The thickness of the saw blade We hope that saw blades, the thinner the better theoretically kerf is actually a kind of consumption. With carbide saw blade sawing plate materials and manufacturing process determines the thickness of the saw blade saw blade. When selecting the thickness of the saw blade should be the stability of the saw blade work as well as the cutting material to consider.

And the diameter of cemented carbide saw blades used for cutting equipment and cutting the workpiece thickness. Saw blade small diameter, cutting speed is relatively low; Saw blade diameter of saw blade and cutting equipment requirement is high, at the same time cutting efficiency is high.

Tooth shape, Angle, the number of teeth, thickness, diameter, the type of carbide combined into a series of parameters, such as hard alloy saw blade as a whole, should reasonable selection and collocation can better play to the advantages of it.
