A grinding wheel is a sharp, hard material used to grind a soft material surface. In recent years, with the continuous optimization and improvement of the material being ground, some new requirements have been put forward on the grinding wheel. So what are the requirements for the grain size of the grinding wheel? Let's take a look at it below.
The particle size of the fiber cutting disc Chinese supplier refers to the particle size of the grinding wheel. The grinding wheel can be divided into four groups of abrasive grains, milling powder, fine powder, and ultrafine powder according to the size of the particles. Among them, the particle size number of the grinding wheel and the grinding wheel are expressed by the number of meshes on the length of each inch of the screen, and the mark is the "#" symbol in the upper right corner of the number of the granular number. For example, 240# means that there are 240 holes in the length of each inch of the screen. The larger the value of the grain size, the smaller the abrasive grains. The particle size numbers of the two groups of fine powder and ultrafine powder are expressed by the actual size of the particles, and the mark is to add a letter "W" in front of the particle size number. Sometimes it can be folded into a mesh number. For example, W20 means that the actual size of the grinding wheel particles is between 20 μm and 14 μm, and the mesh number is 500#.
There are coarse, medium and fine particles in the particle size of various grinding wheels. The medium particle is the basic particle size in the grinding powder, which is the main factor determining the grinding ability of the grinding wheel, and it occupies a large proportion in the particle size composition. The practice has proved that the grinding powder after centrifugal sorting will have a grinding capacity of 20% higher than that before sorting. The fine particles play a small grinding role in the grinding. The particle size is not only detrimental to the quality of the abrasive workpiece but also reduces the grinding efficiency. The amount of the fine particles should be minimized in the particle size composition. Therefore, from the efficiency of grinding and the quality of work, the particles of the 230*3*22 sharp cutting off wheel are required to be uniform. The abrasive grain group with the particle size of 12#~80# has a large particle size and is not suitable for the grinding wheel for grinding.
In the production process, the particle size of the grinding wheel only meets the above requirements, which is suitable for our use. However, there are still some details on the grinding wheel production that need attention.
