Abstract: In the grinding processes, the distribution and arrangement of the abrasive grains on the grinding wheel affected the form of interaction between the abrasive grains and the workpiece materials, the order of grinding trace distribution and the material removal characteristics, which determined the grinding surfaces, sub-surface quality, grinding forces, et al. Compared with the grinding wheel with random distribution of abrasive grains, the ordered grinding wheel helped to reduce the grinding forces and grinding temperature during processing and improve the life and grinding performance of the grinding tools by reasonably adjusting the positions and distribution modes of abrasive grains on the grinding wheel surfaces, which helped the abrasive grains on the grinding wheel surfaces to have uniform forces and reasonable size of chip holding spaces. At present, the research on super-hard grain ordered grinding wheels was a relatively mature research direction with earlier development and more related theories than that on ordered grinding wheels such as abrasive clusters and structured grinding wheels. The research status of super-hard abrasive ordered arrangement wheel preparation was reviewed herein. Then, the theory and application status of super-hard abrasive wheel with directional arrangement, phyllotactic arrangement and other arrangement were discussed. Finally, the future research directions of super-hard abrasive grain controllable arrangement grinding wheels was discussed.

Key words: controllable grinding abrasive, directional arrangement, abrasive phyllotactic pattern arrangement, concentric circle arrangement
