Carbon-contained nanotube reinforced nano ceramic binding agent diamond grinding wheel and manufacturing method thereof
The invention discloses a carbon-contained nanotube 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, polyamide fibers are added into the raw production materials of the grinding wheel so as to effectively increase the holding intensity of the grinding materials and the binding agent; the toughness of the diamond grinding wheel can be increased effectively through carbon nano tubes, and the grinding precision is improved. The diamond grinding wheel is good in grinding performance, the grinding speed can be obviously increased, hardness is high, toughness is good, and the grinding wheel is durable.
