A grinding wheel is composed of three basic elements: abrasive grains, a bond, and pores. The abrasive grains perform the cutting action, the bond holds the grains together, and the pores refer to the voids between the grains, between the grains and the bond, and within the bond itself.
Apart from the differences in their microstructure compared to ceramic grinding wheels, large-pore grinding wheels are otherwise similar. They use the same raw materials, and the wheel size and hardness are the same. Their manufacturing methods are similar, the only difference being that in the production of large-pore grinding wheels, some pore-forming agents are added to the mixture, completely volatilizing before the wheel is formed, thus creating the large pores. Today, we'll discuss the advantages of large-pore grinding wheels. Let's delve into this topic together.
Large-pore grinding wheels have a less dense structure, and the pore size is much larger than that of other abrasive grains. Therefore, large-pore grinding wheels have unique characteristics, such as the fact that they do not easily clog during grinding and are particularly suitable for rough and fine grinding of non-ferrous metals, rubber, leather, and plastics. They also offer advantages in terms of durability and cutting ability. Furthermore, they have a fast heat dissipation rate and perform well when grinding heat-sensitive materials, workpieces, and in dry grinding processes.
The abrasives used in large-pore grinding wheels are generally chosen for their good thermal and electrical conductivity, high hardness, and sharpness—carbides and alumina, such as green silicon carbide and white alumina.
When selecting a large-pore grinding wheel, choose one that's right for your needs; don't blindly follow the crowd.
