The invention discloses a technique for controlling a precision hole anode oxidization process for a 2A12-T4 aluminum alloy part. According to the technique, an oxidizing tool is prepared by adopting titanium alloy; the oxidizing tool adopts a titanium wire; one end of the titanium wire is provided with an external thread which can be matched with a connecting threaded hole in the 2A12-T4 aluminum alloy part; the other end of the titanium wire is made in a hook shape and can be hung on an anode conducting rod during oxidization; before the oxidization process, the Phi9 precision hole reversed membrane allowance dimension of the aluminum alloy part is machined as FORMULA (shown in the description). By determining the preliminary dimension of Phi9 hole diameter membrane allowance, the technique disclosed by the invention is combined with a technique of a titanium alloy oxidizing tool to obtain the Phi9 hole diameter dimension after oxidization; the thickness of the oxidized membrane and the insulativity of the
