Abrasives play a cutting role in grinding tools. Adhesive is a material that solidifies loose abrasives into grinding tools, and there are two types: inorganic and organic. Inorganic binders include ceramics, rhodochrosite, and sodium silicate; Organic materials include resin, rubber, and insect glue. The most commonly used ones are ceramic, resin, and rubber binders.
Pores play a role in containing and removing debris during grinding, and can accommodate coolant, which helps dissipate grinding heat. To meet certain special processing requirements, certain fillers such as sulfur and paraffin can also be impregnated into the pores to improve the performance of the grinding tool. This filler is also known as the fourth element of grinding tools.
The items that represent the characteristics of ordinary abrasive bonded abrasives include: shape, size abrasive, particle size, hardness, microstructure, backing, backing adhesive, and binder. The hardness of a grinding tool refers to the ease with which abrasive particles detach from the surface of the tool under external force, reflecting the strength of the binder holding the abrasive particles.
