ActiveBonded abrasives—Determination and designation of grain size distribution—Part 2:Microgrits
固结磨具用磨料 粒度组成的检测和标记 第2部分：微粉
Application Summary AI generated
This standard specifies the test methods and designation rules for the grain size distribution of microgrits used in bonded abrasives. It is applied in the manufacturing of precision grinding wheels, honing stones, and superfinishing abrasives, particularly for industries requiring fine surface finishes such as automotive, aerospace, and tooling. The standard ensures consistent particle size classification for microgrits (typically finer than 240 mesh) to control grinding performance and workpiece quality.
