Calcium sulfate crystal whisker reinforced nanometer ceramic bond diamond grinding wheel and preparation method thereof
The invention discloses a calcium sulfate crystal whisker reinforced nanometer ceramic bond diamond grinding wheel. In the preparation process of the grinding wheel, raw materials such as nano-graphite, beta-eucryptite, nanometer-level silicon dioxide and nanometer-level aluminum oxide are mixed and calcined, nanometer-level composite nanometer ceramic bond is prepared, and the nanometer-level composite nanometer ceramic bond has higher strength, higher toughness and lower sintering temperature compared with common ceramic bond, is better in high-temperature wettability, low in heat expansion coefficient, and good in maneuverability for abrasives. In addition, calcium sulfate crystal whiskers added into the raw materials have obvious reinforcement, toughening, abrasion resistance and other effects, and the use performance of the grinding wheel is greatly improved. The prepared diamond grinding wheel is good in grinding performance and higher in grinding precision, and the grinding speed can be obviously improved.
