Electric Discharge Machining Surface Finishes
我们提供美观和性能兼备的表面处理：阳极氧化、抛光、喷砂、涂层和热处理。让我们找到最合适的产品！
机械加工
这种机加工表面粗糙，有工具痕迹，是最基本的表面处理形式，没有任何额外的精加工或抛光。
阳极氧化
它能在铝上形成一层保护性氧化层，提高耐腐蚀性和硬度，还能进行染色以改善外观。
抛光
抛光可使表面光滑如镜，改善外观，减少粗糙度，同时提供一定的防腐蚀保护。
拉丝处理
拉丝表面具有细密的平行线条，看起来质感十足，可增强抓握力并减少指纹。
喷砂
喷砂使用高压空气和研磨颗粒来清洁或纹理表面，从而增强涂层的附着力。
电抛光
电抛光是一种电化学工艺，可使金属表面光滑、光亮，去除瑕疵并增强耐腐蚀性。
