What factors mainly determine the characteristics of the grinding wheel?

The characteristics of the grinding wheel are mainly determined by five factors: abrasive, particle size, binder, hardness and organization. 12

Abrasive: The main raw material of the grinding wheel, responsible for cutting work, needs to have high hardness, good heat resistance and certain toughness. Common abrasives include corundum and silicon carbide, which are suitable for different grinding needs.

Particle size: refers to the size of the abrasive particles, which affects the roughness and productivity of the machined surface. Coarser abrasive particles are used for rough grinding, and finer abrasive particles are used for fine grinding.

Binder: The substance used to bond the abrasive, which affects the strength, impact resistance, heat resistance and corrosion resistance of the grinding wheel. Common binders include ceramic binders, resin binders, rubber binders and metal binders.

Hardness: The ease with which the abrasive particles on the surface of the grinding wheel fall off under the action of grinding force. The softer the hardness, the easier it is for the abrasive particles to fall off, while the harder the hardness, the harder it is for the abrasive particles to fall off.

Organization: refers to the proportional relationship between the volumes of the abrasive particles, binders and pores, which affects the tightness and grinding performance of the grinding wheel. The tissue status is divided into tight, medium, and loose, which are subdivided into multiple levels.
