Materials for customized blades
　　The material of the blade is the factor that determines the cutting performance of the blade, which has a great influence on the machining efficiency, machining quality, machining cost and the durability of the blade.The harder the customized blade material is, the better its wear resistance is, the higher the hardness is, the lower the impact toughness and the brittle the material is.
　　Geometric problems of blade customization
　　Choosing the right geometric Angle helps to reduce the vibration of the customized blade. In turn, the graphite workpiece is not easy to collapse.
　　Customized coating for blade
　　Coated blade has the advantages of high hardness, good wear resistance and low friction coefficient.
　　According to the above points, the material, geometric Angle, coating, edge strengthening and machining conditions of the cutter play different roles in the service life of the blade.
