Abstract
The invention relates to the technical field of grinding wheel manufacturing, in particular to a ceramic zirconium corundum grinding wheel and a production technology thereof. The grinding wheel is made from the following raw materials of, by weight, 34-37 parts of zirconium corundum abrasive materials, 12-14 parts of mullite, 30-34 parts of single-crystal corundum abrasive materials, 12-14 parts of cubic boron nitride abrasive materials, 3-4 parts of silicon dioxide, 2-3 parts of magnesium oxide, 1-2 parts of borax, 14-18 parts of titanous sulfate, 1-2 parts of lanthanum oxide and 10-12 parts of auxiliaries. According to the grinding wheel, a ceramic bonding agent formed by sintering the raw materials such as the mullite, the silicon dioxide, the borax, the titanous sulfate and the lanthanum oxide is adopted, and the bonding agent is stable in performance, resistant to abrasion, low in fir-resistant degree, small in thermal expansion coefficient and high in holding strength with the abrasive materials, so that the bonding firmness between the abrasive materials is effectively improved. Thus, the zirconium corundum grinding wheel has good rigidity and cutting performance, and is longer in service life compared with a traditional zirconium corundum grinding wheel.
