The focus of the present work is to examine the differences in microstructure, hardness, abrasion and impact toughness of grinding media from eight different manufacturing sources.

Robotic Instrument for Grinding Rocks into Thin Sections ...

All cutting, grinding and finishing operations are performed automatically on the machine without any need for hand-held grinding. This ensures the stable production of thin sections with an even thickness over the whole area of the specimen, as well as a reproducible thickness from thin section to thin section.

Rock microstructure - Wikipedia

The center of grinding ball A was not hardened, so the performance was poor. Figure 6 shows that the surface of grinding ball B was a mixed martensite structure. At 1/2 R, the microstructure mainly included martensite and a very small amount of bainite. At the center, the microstructure was composed of martensite and a small
