Features and Production Range of Grinding Wheel with Big Pores

Grinding wheel with big holes is not easy to be blocked, and has high durability and strong cutting ability during grinding. It is suitable for coarse and fine grinding of soft metal and non-metallic materials such as plastic, rubber and leather.

At the same time, it has the characteristics of faster heat dissipation, so workers will find it has good effect when used for grinding some heat-sensitive materials, thin-walled workpieces and dry grinding process (such as the cutter grinding of cemented carbide cutting tools and machine tool guide rail, etc.).

The manufacturing methods of grinding wheel with big pores and general vitrified bond grinding wheel are essentially the same. The difference is to add a certain amount of pore forming agent in the ingredients, and it will be completely evaporate and burn out before grinding wheel sintering, and then produce big pores.

It generally uses carbide and corundum in the aspect of abrasive grains, such as the commonly used black silicon carbide (C), green silicon carbide (GC) and white fused alumina (WA) and so on.

These abrasive grains are sharp and brittle, and have high hardness, good thermal conductivity and electrical conductivity; The particle size (36 # ~ 180 #); The bond (vitrified bond); The hardness at all levels (G ~ M); The shape (flat, cup, bowl, or dish, etc.); The pore size (about 0.7 ~ 1.4 mm).
