铝件面积大，，，在氧化槽内摆动过大，，，边沿和中心部位与溶液的接触、更新、交流有很大的区别，，，从而导致氧化膜色彩纷歧。。。。。。
解决要领：
氧化时工件摆动的幅度要小，，，静处置惩罚也可以，，，但当溶液温度过低时容易泛起地图状花斑，，，显得不自然。。。。。。
用镀锌铁丝绑扎氧化件。。。。。。
解决要领：
铁丝使用前必需先退除锌层。。。。。。
Sandblasting conductive oxidation mechanical CNC precision machining,
The surface of the piece is large and moves greatly in the gasification tank, resulting in significant differences in contact, renewal, and exchange with the solution at the edges and center, leading to inconsistent colors of the oxide film.
resolvent:
The amplitude of workpiece oscillation during oxidation should be small, and static treatment can also be used. However, when the solution temperature is too low, map like flower spots are prone to appear, which appear unnatural.
Tie the oxidized parts with galvanized iron wire.
resolvent:
The zinc layer must be removed before using the wire.
