The invention discloses a manufacturing process of an aluminum alloy wheel. The manufacturing process of the aluminum alloy wheel comprises casting, deburring, soaking, spinning, heat treatment, gateremoving, X-ray, and machine addition. According to the manufacturing process of the aluminum alloy wheel, the cost is saved by about 18 yuan/part from the casting production efficiency, the improvingof products quality, the saving of original cooling compressed air, the cancelling of pre-machine addition, the temperature preheating and spinning of blank strip and the temperature pretreating of blank strip and the like; the weight of finished products are reduced by 0.7-1.1 kg, the comprehensive manufacturing cost of the aluminum alloy wheel is even with that of a common casting wheel, and and the market competitiveness of a casting and spinning wheel is improved; and short-flow, lightweight and low-cost technology for manufacturing the cast and spinning wheel is realized, the intelligentization of machining is realized, and the manufacturing process is suitable for automatic production of large-scale casting and spinning wheels.
