The invention discloses a machining process of an imitated-stone aluminum plate and relates to an aluminum plate surface processing technology. The machining process solves the problem that a person cannot feel stone textures when stroking the surface of a prior imitated-stone aluminum single plate. The main points of the technical scheme of the machining process are as follows: a. surface texturemachining; b. surface texture processing; b. cutting; c. cleaning; d. acid pickling; e. ground painting; g. texture spraying; h. sand blasting; and i. detection. According to the machining process, textures on the surface of the aluminum plate are machined into protrusions and concavities, and the surface of the aluminum plate is subjected to sand blasting processing, so that machined positions of the imitated-stone aluminum single plate feel uneven like protruding and concaving textures and rough like stone surfaces.
