carbide saw blade quality and quality of processed products are closely related

Carbide saw blade containing the type of alloy, the substrate material, diameter, number of teeth, thickness, profile, angle, diameter and other parameters that determine the processing capacity grinding cup wheels  and cutting blade. Select the saw blade sawing according to the type of material, thickness, cutting speed, cutting direction, feed speed, kerf width requires the correct selection of blades.
(A) the choice of carbide species
Commonly used types of tungsten carbide cobalt (code YG), tungsten titanium category (Code YT). Since tungsten carbide cobalt impact resistance is better in the wood processing industry more widely used. Commonly used in wood processing model YG8-YG15, YG behind the numbers indicate the percentage of cobalt, cobalt content increases, the alloy impact toughness and flexural strength has increased, but the hardness and wear resistance has declined, to be selected according to the actual situation.
(B) the choice of substrate
1.65Mn spring steel elastic and plastic, material economy, good hardenability, the heating temperature is low, easy deformation can  General purpose blade be used for less demanding requirements of the cutting blade.
(2) high carbon tool steel carbon high thermal conductivity, but by the temperature of 200 ℃ -250 ℃ sharp decline in its hardness and wear resistance, heat deformation, poor hardenability, tempering longer easy to crack. Materials such as tool manufacturing economy T8A, T10A, T12A and so on.
3 alloy tool steel and carbon tool steel, heat resistance, wear resistance, good processing performance, heat distortion temperature of 300 ℃ -400 ℃ suitable for manufacturing high-grade alloy circular saw blades.
4 high-speed tool steel has good hardenability, hardness and rigidity, less heat deformation, is ultra-high strength  core bits for concrete steel, high-grade thermoplastic stable suitable for manufacturing thin blades.
(C) the choice of diameter
Saw blade diameter with the use of cutting equipment and cutting the workpiece thickness. Saw blade diameter is small, the cutting speed is relatively low; Saw blade diameter and sawing equipment requirements for the necessary high, while the cutting efficiency is high. Depending on the diameter of the blade circular sawing machine model selection with a diameter matching blades.
Standard parts diameter: 110MM (4 inches), 150MM (6 inches), 180MM (7 inch), 200MM (8 inches), 230MM (9-inch), 250MM (10-inch), 300MM (12-inch), 350MM ( 14-inch), 400MM (16-inch), 450MM (18-inch), 500MM (20-inch), etc., precision panel saw blade multi bottom slot designed to 120MM.
(D) selection of teeth
Serrated teeth, in general, the more teeth, in the unit time, the more the cutting edge, cutting as possible, but the number of cutting teeth carbide required more and more, the high price of the blade, but too close serrated , teeth of the chip becomes small, easy to cause the blade fever; another jagged too, when the feed rate mis-match, then cut each tooth small amounts, will exacerbate friction with the workpiece edge, affecting the life of the blade . Typically tooth spacing 15-25mm, material selection should be based on a reasonable cutting teeth.
