Ten reasons alloy saw blade wear

1, the phase change wear alloy blade at a certain friction during high speed cutting , the substrate or the material at temperatures above the phase transition temperature , causes the alloy saw blade with  cutting tools accelerated wear , thus losing the cutting ability . Such as high speed steels 500-600 °, ordinary steel 100 °, alloy steels 300-350 °, 65 manganese steel 200 ° temperature inside will result in the matrix phase transitions.
2 , the alloy microstructure in the welding temperature or other factors in the destruction of high -density ultra- fine particles in the welding alloy cold and hot temperatures , or high temperature , resulting in thicker alloy crystal , alloy cracking, deformation of the matrix alloy strength reduction and abrasion resistance .
3 , tool wear, cutting angle design and brick saws  material discrepancies due to different hardness and various types of plastic materials not targeted under the appropriate choice of alloy , and no matter according to the hardness of the cutting dry cutting angle of each side effect which reduces tool life .
4 , the oxidation of the alloy blade wear oxidation wear at 800 ° C or higher friction temperature, oxygen in the air and alloys of cobalt , tungsten carbide, titanium, tool wear due to oxidation occurs .
5, the impact of technology and precision grinding wear, alloy circular saw blades are precision cutting tools, any main and sub- edge blade with tape, face cutting straight face , or radial cutting rather than a cutting line, each one formed alloy cutting point or depth , and many other factors that reduce their effectiveness .
6 , diffusion wear diffusion is a chemical wear, diffusion wear is at a high cutting tool and the workpiece between the mutual diffusion of alloying elements , the tool material physical and mechanical properties of reduced lead increased tool wear . Carbide, titanium carbide increased in the tantalum carbide or other additives can be added to improve the matrix alloy and the temperature of diffusion and thus improve tool wear resistance and heat resistance.
7 , adhesive wear in the cutting of plastic material , the cutting and the rake face after the cutting work viscosity, the tool surface or partially lower strength adhesive particles or the  circular saw   workpiece to be cut so that the tool with grinding brush wear.
8 , improper maintenance or improper operation caused by wear and tear , each cutting equipment, cutting feed rate is not the same , while the alloy saw blade is designed according to different cutting material various angles , with inappropriate will reduce its effectiveness.
9 , mechanical wear workpiece or the tool cutting edge surface carved with shades of grooves caused by wear and tear. Workpiece or cutting edge tool and the workpiece with high hardness more than the smaller tool easy to wear, so the tool must have a higher hardness.
10 , the tool wear buildup feed speed is too fast or accuracy is not high , wheel selection and other factors, is not a good grinding blade with the cutting tool material during shock loading or poor toughness , tool face angle for each blade will have a loss factor with from.
