alloy circular saw blades worn mainly

1, the mechanical wear such wear is cutting edge with the workpiece or the tool surface grooves carved shades caused by wear and tear. The workpiece or tool and the cutting edge with high  concrete cutting blade hardness of the workpiece, the tool is smaller than the more easy to wear, so the tool must have a high hardness, in order to improve its wear resistance. 2, 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 workpiece to be cut so that the tool with grinding brush wear. 3, diffusion 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. Diffusion is the wear of a chemical nature, such as cemented carbide or titanium carbide added to tantalum carbide and other additives can be  12 inch saw blade added to improve the matrix alloy and the temperature of diffusion and thus improve tool wear resistance and heat resistance. 4, the phase change alloy blades wear use different materials, heat treatment technology or matrix poor too thin, at a certain speed cutting friction process, substrate or material at temperatures above the phase transition temperature, makes the alloy saw blade with accelerated wear, thus losing the cutting ability. Such as ordinary steel 100 °, 65Mn200 °, alloy steel 300-350 °, high-speed steel temperature at 500-600 ° within the matrix phase change will cause. 5, the oxidation is a chemical oxidation wear wear wear, it is 800 degrees or more friction temperature, oxygen in the air and alloys of cobalt, tungsten carbide, titanium, tool wear due to oxidation occurs. 6, the tool wear buildup accuracy is not high or too fast feed rate, wheel selection, and many other factors or unground good blade with the cutting tool material during shock loading or poor toughness, tool face angle for each band will have a shedding blade factors together. 7, soldering temperature is too high or other factors undermine alloy microstructure, high-density ultra-fine particles in the welding alloy cold and hot temperatures, or high temperature, resulting alloy cracking, alloy crystal thicker, lower alloy matrix strength and deformation durability. 8, angle design and cutting material discrepancies caused by tool wear, and all kinds of plastic materials with different hardness not targeted under the correct selection of a suitable  cutting blades alloy, nor according to the hardness of the cutting material dry cutting angle of impact of each plane thereby reducing tool life. 9, sharpening precision and process affect 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. 10, improper operation or maintenance of the wear and tear caused by improper, 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.
