To improve the grinding and polishing efficiency and the heat dissipation effect, the distribution mechanism of abrasive grains on the grinding disc was studied, and the concept of regional landform optimization based on grinding and polishing conditions was put forward. Regional landform optimization showed that diamonds were uniformly distributed in inclined surface of the grinding disc and were densely packed on outer edges of the grinding disc. The landform of abrasive grains arranged in clusters of parabolic phyllodes can make the abrasive grains evenly distributed and have the best heat dissipation effect by phyllodes theory. The trajectory simulation of the abrasive particle arrangement of different landforms confirms this conclusion.

为了提高磨抛效率和散热效果，研究了磨粒在磨盘上的分布机理，提出了基于磨抛条件的区域地貌优化概念。区域地形优化表明，金刚石均匀地分布在砂轮的倾斜表面上，并密集地堆积在砂轮的外边缘。按照叶状体理论，以抛物线状叶状体簇状排列的磨粒地貌可以使磨粒均匀分布，并具有最佳的散热效果。对不同地貌的磨料颗粒排列进行轨迹模拟，证实了这一结论。
