The organization of grinding wheel reflects the proportional relationship among grinding grains, adhesive and pores. The larger the proportion of grinding grains in the total grinding wheel, the denser the grinding wheel tissue and the smaller the porosity. Grinding wheel organization is divided into three grades: compact, medium and loose. It was subdivided into 13 tissue Numbers, ranging from 0 to 13. The smaller the number, the denser the tissue.
Generally, if the grinding wheel is not marked with the tissue number, it means the medium tissue.
Compact grinding wheel: tissue no. 0-3, grinding grains account for more than 55% of the grinding wheel volume, compact grinding wheel grinding tool is suitable for grinding under gravity. In forming grinding or precision grinding, compact grinding wheel can keep the formability of grinding wheel, and can get less roughness.
Medium tissue grinding wheel: tissue no. 4-7, grinding grains account for 54-58% of the grinding wheel volume. Suitable for general quenched steel and cutting tool grinding.
Loose tissue grinding wheel: tissue no. 8-12, grinding grains account for 46-38% of the grinding wheel volume. Loose structure grinding wheel is not easy to block, used in surface grinding, inner circle grinding and other processes with large grinding contact area, as well as grinding materials or thin workpiece with strong thermal sensitivity.
