The grinding wheel is the main tool for grinding, which is a porous object composed of abrasive and bonding. Among them, the grinding wheel abrasive, particle size, bonding agent, hardness, tissue, shape and size is an important factor in determining the quality of the grinding wheel. Let us let us know together.
1. Abrasive-abrasive refers to the material of sand in the grinding wheel, is the main component of the grinding wheel, is the fundamental element of the grinding wheel.
2, granularity - particle size is used to represent parameters of the size of the abrasive particle size. According to the basic particle size of abrasives, 41 granularity numbers are set. The particle size directly affects the quality and productivity of the grinding.
3, the binding agent-binding agent is a material used to bond the dispersed abrasive particles into abrasive tool having a certain shape and sufficient strength. The types and properties of the binding agent will affect the hardness, strength, corrosion resistance, heat resistance and impact resistance of the grinding wheel.
4, hardness - grinding wheel hardness refers to the extent to which abrasive particles fall off under external force when the grinding wheel is working. The grinding wheel is hard, indicating that the grinding is difficult to fall off; the grinding wheel is soft, indicating that the grinding wheel is easy to fall off.
5. The tissue of the tissue-grinding wheel refers to the ratio relationship between abrasive particles, binding agents, and pores of a grinding wheel. It is usually classified in a percentage of the amount of grinding wheel accounted for abrasive grains. There are three tissue states of the grinding wheel: close, medium, loose; finely divided into 0-14, a total of 15 levels. The smaller the organizational number, the larger the proportion of abrasive particles, the closer the grinding wheel; it is, the larger the organizational number, the smaller the scale ratio, the less the grinding wheel.
6, the shape and size - the shape and size of the grinding wheel is determined according to the type of grinding machine, processing method and workpiece.
As abrasives, binders and grinding wheel manufacturing processes, the characteristics of the grinding wheel may differ, and the accuracy, roughness and production efficiency of grinding processing are important. Therefore, the suitable grinding wheel must be selected depending on the specific conditions. Welcome to the Ming Sha abrasive.
