The grinding efficiency of diamond burs
The Journal of Prosthetic Dentistry, 1979Deterioration of round diamond burs during 8 minutes of operation was found to be more pronounced for burs with low particle densities than for burs with high particle density. No definitive relationship was found between the initial grinding rate and initial particle density.

Grinding performance analysis of diamond wheel for groove grinding
IEEE ICCA 2010, 2010This study utilized sintered tungsten carbide-based hard metals (HRA 92.3 and referred to as tungsten carbide or WC hereinafter) as the workpiece, testing and comparing the performance of each diamond wheel. The experiment was to cut the groove of a double-end mill and the cut behavior was creep feed grinding.

The optimal diamond wheels for grinding diamond tools
The International Journal of Advanced Manufacturing Technology, 2003Grinding is the most suitable process for manufacturing good quality diamond tools. In this paper, diamond wheels have been studied. From the grinding of polycrystalline diamond (PCD) insets, the effects of certain factors such as the bonding material, the grit size and structure of a diamond wheel have been investigated. It is concluded that vitrified

Grinding Performance of Diamond Grinding Tools for Sapphire Crystal
Advanced Materials Research, 2014In order to improve the efficiency and reduce the cost of sapphire crystal machined by loose abrasive lapping, the fixed-abrasive diamond grinding tools for sapphire grinding were investigated in this paper. Four vitrified-resin composite bond diamond grinding tools with different grain sizes (40μm, 20μm, 7μm, 2.5μm) were developed.

Lithia-rich vitrified bonded diamond grinding wheels for grinding polycrystalline diamond tools
International Journal of Machining and Machinability of Materials, 2009A vitrified bond based on the Li2O-Al2O3-SiO2 glass ceramic system was used to bond diamond grains to form a grinding wheel capable of grinding polycrystalline diamond compacts (PDC). Several factors that influence the properties of the grinding wheel such as the quantity of vitrified bond and the type of filler in the grinding wheel were investigated.
