|Description||The dicing sheets are all available in a range of sizes and are selected for the object to be processed and requirements. 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 particles is divided into two categories. 12#-280# is called: sand. W40-W0. 5 (or finer) is called micro powder. 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# is also used to indicate the particle size of the abrasive particles with XXX#--XXXX#. 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 selected grinding wheel is too high or too high. If it is too high, the metallographic structure of the burn will appear. 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 6 inch es cutting disc 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 resin EN12413 cutting discs, 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, and the silicon carbide material itself has smaller chemical activity than alumina, better cutting performance, less burn, and less wear. Again, the particle size is chosen to favor cutting. If the sharpness is required, the coarser grain size should be used. If the cutting requirements are high precision, abrasives with a finer grain size should be used. In short, the problem in the cutting process should be determined first in the hardness and material of the sample. In the targeted selection of cutting material.|
