Selection Of Alloy Types For Non-ferrous Metals Saw Blades

    Woodworking saw blade is the most commonly used cutting tool for woodworking. The quality of woodworking saw blade is closely related to the quality of processed products. Correct and rational selection of carbide saw blade for improving product quality, shorten the processing cycle, reduce processing costs is of great significance.

    The woodworking saw blade contains the type of the alloy blade, the material of the base, the diameter, the number of teeth, the thickness, the tooth shape, the angle, the aperture and so on. These parameters determine the processing capacity and cutting performance of the saw blade. Select the blade according to the type of sawing material, thickness, sawing speed, the direction of sawing, feeding speed, saw the width of the need to correctly select the blade.

    Carbide commonly used types are tungsten cobalt class (code YG), tungsten and titanium (code YT). As the tungsten cobalt carbide impact resistance is better, in the wood processing industry to use more widely. YG8-YG15 is commonly used in wood processing, and the number after YG indicates the percentage of cobalt content, the cobalt content increases, the impact toughness and flexural strength of the alloy are improved, but the hardness and wear resistance are decreased. According to the actual situation to be selected.Non-ferrous Metals Saw Blades

1, the choice of the substrate: 65Mn spring steel elasticity and plasticity, material economy, heat treatment hardenability, and its low temperature, easy to deformation can be used for cutting requirements of the blade is not high.

2. Carbon tool steel with high thermal conductivity of carbon, but by 200 ℃ -250 ℃ temperature when the hardness and wear resistance decreased sharply, heat treatment deformation, poor hardenability, tempering time is easy to crack. For the manufacture of economic materials such as T8A tool, T10A, T12A and so on. Multi-chip saw blade

3. Alloy tool steel and carbon tool steel compared to heat resistance, good wear resistance, good handling performance, heat distortion temperature of 300 ℃ -400 ℃ suitable for the manufacture of high-grade alloy circular saw blade.

4. High-speed tool steel has good hardenability, hardness and rigidity, heat deformation is less, is a high-strength steel, thermoplastic stability suitable for manufacturing high-grade ultra-thin blade.Non-ferrous Metals Saw Blades

The number of teeth, in general, the more the number of teeth in the unit time cutting the edge of the more cutting performance, the better the number of cutting teeth, the number of cutting teeth need to use more carbide, saw the price is high, but too close The amount of chips between the teeth smaller, easy to cause the blade fever; the other too much sawtooth, when the feed with the improper, then the amount of each tooth cut very little, will increase the edge of the workpiece and the friction, affecting the blade life The Usually tooth spacing at 15-25mm, should be based on sawing the material to choose a reasonable number of teeth.Non-ferrous Metals Saw Blades
