Brief analysis of the correlation between various parts in the organization of abrasives

The strength of a grinding wheel refers to the ease of breaking when the grinding wheel is subjected to a centrifugal force. When grinding, the strength of the grinding wheel is very important. When the grindstone is not balanced and the center of gravity of the grindstone is not on the centerline of the rotating shaft, it will produce an imbalance.

There are two ways to express the organization of abrasives: one is the percentage of the volume occupied by the abrasive grains in the specific volume of the grinding, which is the so-called abrasive rate; the other is the number and size of the pores in the grinding tools. That is, using the porosity rate. Abrasive bond has a great role in abrasives. The main function of the abrasive bonding agent is to bind many fine abrasive particles together to form a grinding tool, so that it has a certain shape and necessary strength. These composite crushers can be used.

Abrasive organization, the organization of the abrasive tool refers to the volumetric relationship between abrasive particles, binders, and pores in the abrasive tool, and is generally controlled by the formula. At present, China's abrasive abrasive industry has basically established an industrial system that is compatible with the reformed abrasives industry and is basically coordinated with international standards. It is equivalent to international standards and advanced foreign standards, and the number of standards basically meets the needs of industrial production development. standard system.
