[0002] Before the anodizing test of aluminum alloy, the sample surface needs to be sandblasted to remove the processing marks produced by the previous process (grinding or milling) on ​​the sample surface, so as to obtain a sample surface with a certain glossiness and roughness, which is convenient for the anodizing test and the observation of the defects on the sample surface after the anodizing test. A sample surface that is too smooth or too rough or uneven in surface roughness is not conducive to the observation of defects, so the effect of sandblasting is particularly important.

[0003] At present, manual sandblasting machines are often used for sandblasting. That is, the operator wears latex gloves, holds the sample, and inserts the sample into the sandblasting machine by hand. Sand is ejected from the nozzle under the action of compressed air and hits the surface of the sample. The sample is withdrawn after a certain period of sandblasting. This type of sandblasting method relies more on operating experience, and there are large differences in the sandblasting effect when different operators operate it; and because this type of sandblasting method is handheld, it is difficult to accurately control the angle and time of sandblasting, resulting in poor sandblasting effect and uneven sandblasting.
