|Title||What are the models of the cutting blades?|
|Description||First of all, let's first look at the number of objects we generally say. The mesh number refers to the size range of the abrasive particles. The range of sizes of abrasive grains is divided into two categories. 12#-280# is called: sand. W40-W0. 5 (or finer) is called micropowder. XX# is the size of the sieve, which is the mesh size of the first mesh that the abrasive particles can pass to indicate the particle size of the abrasive particles. WXX is the measurement size, that is, the abrasive grain is small and there is no corresponding screen to measure it, and it is represented by its actual average size. Now the abrasive grain size above 280# also uses XXX#--XXXX# to indicate the particle size of the abrasive particles. W40-W10 is close to 320#-800# W7-W2. 5 is close to 1000-3000. Generally, the ordinary grinding wheel can reach W14 (around 600#). The problem that arises now is how to avoid burns during the cutting process and the cutting efficiency is low. The first is whether the grinding wheel selected by the cutting chip manufacturer is too high or too high. If it is too high, the metallographic structure of the burn will appear, and the structure of the material cannot be accurately tested, and errors occur. If the hardness is too low, the cutting efficiency will appear, and the high quality cutting disc supplier will be wasted. How to make the cutting process not burn and sharp, need to test the hardness of the material, and the correct use of the coolant. The second is to select the raw material of the cutting disc for stainless steel, the preferred aluminum material for cutting the metal material, and the silicon carbide material for the non-ferrous metal and non-metal materials. Because the aluminum material used for cutting metal materials does not chemically react with the chemical components in the metal, it is advantageous for cutting. Non-metallic and non-ferrous metals have low chemical activity. The chemical activity of silicon carbide materials is smaller than that of alumina, and the cutting performance is good, the burn is small, and the wear is small.|
