Magnesium borate whisker reinforced nano ceramic binding agent diamond grinding wheel and manufacturing method thereof
The invention discloses a magnesium borate whisker reinforced nano ceramic binding agent diamond grinding wheel. In the preparation process of the grinding wheel, raw materials of nano graphite, beta-eucryptite and the like and nano-scale raw materials of silicon dioxide, aluminum oxide and the like are mixed and calcined firstly to prepare a nano-scale composite nano ceramic binding agent. The nano ceramic binding agent has higher intensity, higher toughness and lower sintering temperature, better high-temperature wettability, lower thermal expansion coefficient and better manoeuvreability for grinding materials compared with a conventional ceramic binding agent. In addition, magnesium borate whiskers are added into the raw production materials of the grinding wheel so as to have the effects of obvious intensity reinforcement, toughness reinforcement, corrosion resistance and the like. The diamond grinding wheel is good in grinding performance, the grinding precision of workpieces is high, and the grinding speed can be obviously increased.
