[0003] In the preparation process of vitrified bond diamond grinding wheel, factors such as the choice of abrasive, vitrified bond, and firing conditions will affect the grinding performance of vitrified bonded diamond grinding wheel, especially the performance of vitrified bond is more important. Traditional The binder generally has high sintering temperature, low strength, and poor wetting and coating on the abrasive, which directly leads to the deterioration of the performance of the diamond abrasive and greatly reduces the grinding performance.

Abstract
The invention discloses a basalt fiber enhanced nano-vitrified bond diamond grinding wheel. In the preparation process of the grinding wheel, raw materials of nano graphite powder, beta-eucryptite and the like and nano-scale raw materials of silicon dioxide, aluminum oxide and the like are mixed and roasted firstly to prepare a nano-scale composite nano-vitrified bond. The nano-scale composite nano-vitrified bond has higher intensity and toughness, lower roasting temperature, better high-temperature wettability and a lower thermal expansion coefficient compared with conventional vitrified bonds, and added nano-hydroxyapatite can further improve the maneuverability of the bond and abrasive materials. In addition, added basalt fibers have the remarkable effects of enhancing the intensity and toughness, resisting cracking, being resistant to temperature and the like. The prepared diamond grinding wheel is good in grinding performance, high in workpiece grinding precision and higher in grinding efficiency.
Description
technical field [0001] The invention relates to the technical field of preparation of a vitrified bond diamond grinding wheel, in particular to a basalt fiber-reinforced nano vitrified bond diamond grinding wheel and a preparation method thereof. Background technique [0002] Diamond abrasives have the characteristics of high hardness, high strength, and good wear resistance. They are widely used in the production of abrasive tools for grinding hard and brittle materials and cemented carbide. Diamond grinding wheels are one of the common types of abrasive tools. According to the requirements of diamond grinding wheels The classification of the bond used can be divided into resin bond diamond grinding wheel, metal bond diamond grinding wheel and vitrified bond diamond grinding wheel, etc. The vitrified bond grinding wheel is made of vitrified bond, diamond abrasive and filler according to a certain ratio. , after high temperature sintering, this kind of grinding wheel can sol...
