The Dialectical Relationship Between Sharpness And Wear Resistance Of Diamond Saw Blades

The dialectical relationship between sharpness and wear resistance of diamond saw Blades

The performance of diamond saw Blades includes two aspects, sharpness and wear resistance. During sawing, the sharpness is the cutting efficiency, and the wear resistance is the length of the Saw blade service life. Efficiency and length of life are two important indexes to measure the comprehensive performance of diamond saw blades.

The purpose of the diamond saw blade design is to make it show the ideal working efficiency and service life in the process of use. The cutting efficiency and the length of the diamond saw blade are closely related to the formulation of the tool head, and the formula of the cutter head depends on the parameters of the selected diamond and the parameters of the carcass.

The higher the average density of diamond in the working face, the better the wear resistance of the tool head, the longer the life of the tool head. On the contrary, the smaller the φ, the worse the wear resistance, the shorter the life of the tool head.

The surface density of diamond in the working layer of the first body of the blade is related to the diamond size and the concentration of diamond in the blade. The higher the diamond concentration in the tool head, the greater the average density of the diamond in the first body face, the higher the wear resistance of the tool head and the longer the service life. The larger the longitudinal density of diamond in the working layer of the blade, the more the diamond layer in the working layer of the diamond carcass, the more the diamond layer in the body, the longer the life of the tool head. The diamond longitudinal density of the working layer of the first body is related to the size and concentration of diamond selected by the cutter head. The higher the diamond concentration, the larger the diamond longitudinal density in the working layer of the tool head, the more the diamond layer in the first body. The finer the grain size of the diamond grains is, the more the diamond layer is in the diamond tire, the higher the wear resistance of the tool head is.

The sharpness of diamond saw blades is related to the bare velocity of the diamond particles contained in the working layer of the carcass surface, the faster the bare speed, the higher the contact friction frequency of the diamond particles and the cut material during the cutting process, the sharper the knife head. The exposed velocity of the particles is determined by the control force of the knife's body binder. The stronger the control force of the carcass, the slower the exposure and shedding rate of diamond particles, and conversely, the weaker the control force of the carcass, the faster the exposed and falling of diamond particles. So, the stronger the control force of the diamond saw blade, the weaker the sharpness of the knife head, the weaker the control force of the carcass, the stronger the sharpness of the knife head.

But the faster the diamond particles are exposed, the more serious the friction wear and impact wear, the faster the particle shedding speed, the faster the longitudinal density of the diamond in the working layer of the knife, the smaller the diamond layer in the working layer of the diamond carcass, and the shorter the life of the tool head.

Thus, the relationship between the sharpness and wear resistance of diamond cutters is mutually restricted, and this is a long one. The higher the sharpness, the lower the wear Resistance: Conversely, the higher the wear resistance, the lower the sharpness.
