Aramid fiber reinforced nano ceramic binding agent diamond grinding wheel and manufacturing method thereof
The invention discloses an aramid fiber reinforced nano ceramic binding agent diamond grinding wheel. In the preparation method 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, chopped aramid fibers are added into the raw materials so as to reinforce the manoeuvreability between the binding agent and the grinding materials and improve the structural density and intensity. The diamond grinding wheel has good intensity and toughness and good grinding performance, the grinding precision of workpieces is high, and the grinding speed can be obviously increased.
