It is a processing technology that selectively reacts with the metal surface through chemical solutions to remove excess materials and obtain high-precision, complex microstructure parts. Its core advantage lies in its ability to efficiently process fine features that are difficult to achieve with traditional mechanical cutting (such as micron-level hole diameters and complex patterns), and the processing process is free of mechanical stress and does not damage the performance of the metal substrate. It is one of the key processes in fields such as precision hardware, electronics, and medical devices.
