The production range of open structure grinding wheel is as follows: abrasives are generally selected from silicon carbide and corundum, such as green silicon carbide (GC), black silicon carbide (C), brown corundum (A), and white corundum (WA). Abrasive is brittle and sharp, high hardness, good thermal and electrical conductivity; abrasive particle size (36#~100#); bonding agent (generally vitrified bonding); hardness (G~Q level); shape (Flat, concave, cup, bowl or dish, etc.); pore size (about 0.7~1.4 mm).
Some grinding wheels are specially made to increase the internal air holes of the grinding wheel to meet the processing requirements. This product should pay attention to the following aspects in its selection:
1. because the open structure grinding wheel has the advantages of high durability, strong cutting ability and not easy to be blocked during grinding, it is suitable for grinding coarse and fine grinding of non-metallic materials such as metal and rubber leather, and plastic.
2. at the same time, because it has the characteristics of fast heat dissipation, it has good effects in grinding some heat-sensitive materials, thin-walled workpieces and dry grinding processes (such as sharpened carbide tools and machine guides).
3. open structuregrinding wheel and other general vitrified grinding wheel manufacturing methods are basically the same. The difference is that a certain amount of pore-enlarging agent is added to the ingredients so that it is completely volatilized or burned before the grinding wheel is sintered, thereby generating atmospheric pores.
