What is a grinding wheel

Grinding wheel is the most important type of abrasive tool in grinding process. The grinding wheel is a porous body made by adding a binder to the abrasive, and then forming a compact, drying and roasting. Due to the different abrasives, bonding agents and manufacturing processes, the characteristics of the grinding wheels are very different, which has an important impact on the quality of grinding, productivity and economy. The characteristics of the grinding wheel are mainly determined by factors such as abrasive, particle size, bonding agent, hardness, organization, shape and size.

There are many kinds of grinding wheels.

According to the abrasives used, it can be divided into ordinary abrasive (corundum and silicon carbide, etc.) grinding wheels, natural abrasive super-hard abrasives and (diamond and cubic boron nitride, etc.) grinding wheels;

According to the shape, it can be divided into flat grinding wheels, beveled grinding wheels, cylindrical grinding wheels, cup-shaped grinding wheels, dish-shaped grinding wheels, etc.; according to the binder can be divided into ceramic grinding wheels, resin grinding wheels, rubber grinding wheels, metal grinding wheels, etc. The characteristic parameters of the grinding wheel mainly include abrasive, particle size, hardness, bonding agent, shape, size and so on.

Because the grinding wheel usually works at high speed, it is necessary to carry out a rotation test (to ensure that the grinding wheel will not break at the highest working speed) and a static balance test (to prevent vibration of the machine tool during work) before use. After working for a period of time, the grinding wheel should be trimmed to restore the grinding performance and correct geometry.

The grinding wheel is a round consolidated abrasive tool with a through hole in the center made of abrasive and bonding agent.

The characteristics of the grinding wheel are determined by factors such as abrasive, particle size, hardness, bonding agent, shape and size.
