The invention discloses a surface treatment process for aluminum products. The surface treatment process comprises the following steps: 1, oil removing procedure, wherein an aluminum product is put into an alkaline solution to remove oil for 20-30 seconds, and then
clean water is used for cleaning the aluminum product for one time; and 2,
grinding procedure, wherein a plurality of silica particles are poured into the
grinding chamber of an industrial vibration
grinding machine, a
silica particle pile is formed, clear water is poured into the grinding chamber of the industrial vibration grinding
machine, the poured clear water submerges the
silica particle pile, and the aluminum product after being treated in the oil removing procedure is poured into the grinding chamber of the industrial vibration grinding
machine. According to the surface treatment process for the aluminum products, the aluminum product after being treated in the oil removing procedure is poured into the industrial vibration grinding machine with the plurality of silica particles to be subjected to grinding, on one hand, the silica particles can
grind burrs on the surface of the aluminum product, on the other hand,
silicon dioxides in the silica particles can neutralize the alkaline solution, and therefore, the aluminum product does not need to be added with an acidic solution for
neutralization after being subjected to the oil removing procedure in the alkaline solution.
