In recent years, polishing brushes and polishing brush wheels with abrasive brush as the main material have been more and more used in industrial production. As a product made of emerging industrial brush materials, abrasive brush It has been favored by many users, but at the same time, many people know little about the knowledge of abrasive wire. For example, one of the important specifications of abrasives is the number of meshes, so what is the number of meshes? What is the difference between the different numbers? This article is briefly introduced as follows.
The so-called mesh number refers to the particle size or thickness of the material. The general definition refers to the number of meshes in the area of 1 inch x 1 inch (the italic part is wrong), that is, the mesh number of the screen, and the material can pass through the mesh. The mesh is defined as the number of meshes: for example, 200 mesh, that is, the material can pass through a screen with 200 meshes in 1 inch x 1 inch. By analogy, the larger the mesh number, the finer the material particle size, and the smaller the mesh number, the larger the material particle size.
The specifications of standard sieves vary from country to country. The commonly used Taylor system uses the number of holes per inch as the sieve number, which is called mesh. For example, a 100 mesh sieve means there are 100 sieves per inch of screen.
The abrasive brush is more and more widely used, thanks to the unique advantages of the brush in deburring and polishing: First of all, the abrasive brush can effectively remove the burrs and burrs on the surface of the workpiece, and perform edge rounding, rust removal, Deoxidized skin, etc. At the same time, the brush can also improve the surface roughness level of the piece by 1-2 levels on the original basis. More importantly, abrasive brush can significantly improve and improve the physical and mechanical properties of the surface of the workpiece, such as eliminating surface stress concentration and micro-cracks, improving surface hardness, increasing the thickness of the wear-resistant layer, improving the performance of the piece, and prolonging the fatigue life, etc.
All in all, the brush can improve the appearance quality and assembly performance of the parts, improve the quality and cleanliness of the whole machine, complete the initial wear of the transmission parts, and shorten the running-in time of the whole machine. Therefore, the abrasive brush can have such a wide range of applications.
