In recent years, with abrasive brushes as the main material for polishing and sanding brushes, polishing brushes and other wheels in industrial production more and more to get more and more applications, as a kind of new industrial brushes made of brush material products, abrasive brushes have been favoured by many users, but at the same time a lot of people on the knowledge of abrasive filament but know very little about it. For example, one of the important specifications of the abrasive material is the mesh number, then what is the mesh number? What is the mesh number? What is the difference between different mesh numbers? This article is briefly introduced as follows.

The so-called mesh, refers to the particle size of the material or the degree of coarseness and fineness, the general definition refers to the area of 1 inch x 1 inch (italicised part of the error) how many mesh number, that is, the number of mesh screen, the material can be passed through the mesh, that is, how many mesh is defined: such as 200 mesh, that is, the material can be passed through the 1 inch x 1 inch within the mesh screen with 200 mesh. And so on, the larger the number of mesh, the finer the size of the material, the smaller the number of mesh, the larger the size of the material.

Standard sieve specifications vary from country to country, commonly used Taylor system is the number of holes per inch of length for the sieve number, called mesh. For example, 100 mesh sieve that every inch of the screen has 100 holes.

A plus or minus sign in front of the mesh number indicates whether or not it can pass through that number of holes. A negative number means that the mesh can be missed, i.e. the particle size is smaller than the mesh size; while a positive number means that the mesh cannot be missed, i.e. the particle size is larger than the mesh size. For example, the particles for -100 mesh ~ +200 mesh, that is, these particles can be missed from the 100 mesh and can not be missed from the 200 mesh, in the screening of this mesh particles, the mesh should be placed in the mesh number of large (200) mesh (100) below the small (100), in the mesh number of the large (200) mesh left behind that is -100 ~ 200 mesh particles.

Abrasive wire brush working characteristics

Abrasive wire brush is more and more widely used, thanks to the unique advantages of the brush in deburring and polishing processing: first of all, the abrasive wire brush can effectively remove pieces of surface processing after the burr, flying edge, edge rounding, rust removal, to remove oxidation skin, etc.; at the same time, the brush can also be based on the original to improve the pieces of the surface roughness level of 1-2; more importantly, the abrasive wire brush can make the pieces of the surface physical More importantly, the abrasive wire brush can make the physical and mechanical properties of the surface of the piece get obvious improvement and enhancement, such as eliminating the surface stress concentration and microscopic cracks, improving the surface hardness, increasing the thickness of the wear-resistant layer, improving the performance of the piece, and prolonging the fatigue life.

Abrasive Wire Brush

In a word, the brush can improve the appearance quality and assembly performance of the pieces, improve the quality and cleanliness index of the whole machine, complete the initial wear and tear of the transmission parts, and shorten the factory break-in time of the whole machine. Therefore, the abrasive wire brushes can have such a wide range of applications.
