充电桩外壳铜饰件平整度要求

问：充电桩等新能源设备上的铜质装饰条对打平有什么要求？答：工业外壳件通常要求平面度 ≤0.5 mm/m 且无目视锤痕，打平重点在"匀"不在"光"：用近平面锤面低力度全覆盖走锤 2–3 遍，锤痕重叠约 70%；退火安排在初平之前一次完成，避免成品再度变形。之后以振动研磨或拉丝统一表面，不必追求镜面。
Q: What planishing do copper trims on EV chargers and other e-mobility hardware need? A: Enclosure parts usually specify flatness ≤0.5 mm/m with no visible hammer marks—aim for "even", not "bright": full-coverage passes at low force with a near-flat face, 2–3 rounds at ~70% mark overlap; anneal once before first planishing so the finished part stays true. Unify the surface afterwards with vibratory finishing or brushing—no mirror needed.
