Optimum and arrangement technology of abrasive topography for brazed diamond grinding disc

Abstract

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.
