Abstract
Abstract In this paper, the preparation of nano-AlN modified Na 2 O–B 2 O 3 –SiO 2 vitrified bond diamond tools with various porosities is reported. The effects of porosity on the impact strength and grinding properties of the wheels for grinding PCD blades are also discussed. The results show that the porosity not only affects the impact strength of the wheels but also the grinding properties, such as the grinding efficiency, the self-dressing, the service life and the surface roughness of the work pieces. The optimum porosity for nano-AlN modified Na 2 O–B 2 O 3 –SiO 2 vitrified bond diamond wheels for grinding PCD tools is approximately 40.5 vol%.
