Ohki uses aluminium alloy billet of 6063 and other grades to make extrusions.

Ohki主要采用6063和其他规格的铝合金锭生产挤压制品。

So this paper research on the method of polish by digitizing for A-alloy motor wheel cured face, realized to wheel automatic polish.

因此，本文结合生产实际，提出了一种铝合金汽车轮毂曲面数字化抛光方法，实现轮毂的自动化抛光。

Then, the method of polish by digitizing for A-alloy motor wheel cured face was suggested. And a automatic prototyping was designed, it based this method..

在此基础上，结合数字化仿形加工对复杂曲面的加工方法，提出了铝合金汽车轮毂曲面数字化抛光方法，并按此方法，设计了自动抛光样机。

Consideration of microstructure, the metal material has a face-centered cubic lattice of the austenitic steel, Reducing Valves copper and aluminum do not appear in the low temperature low temperature brittleness, but the hardness of aluminum and aluminum alloys is not high, the sealing surface of the wear-resistant aluminum , anti-scratch performance is poor, so the use of low-temperature valves have certain limitations, only used in low voltage and small-caliber valve.

从金相考虑，金属材料中具有面心立方晶格的奥氏体钢、铜和铝在低温状态下不会出现低温脆性，但因铝及铝合金的硬度不高，铝密封面的耐磨、耐擦伤性能差，所以在低温阀门中的使用有一定的限制，仅用于低压和小口径阀门中。
