chemical etching and tradition machining

What are the key differences between chemical etching and tradition machining in terms of precision?
Material Stress and Distortion: Traditional machining methods, like stamping or milling, often induce stress and deformation on delicate materials. Chemical etching, by contrast, removes material through a controlled chemical process, leaving no mechanical stress on the workpiece.

Intricate Designs: Chemical etching allows for finer, more intricate designs with tolerances up to ±0.01 mm, which is challenging for traditional machining methods that struggle with complex geometries and sharp corners.

Surface Finish: Chemical etching provides a smooth, burr-free finish, eliminating post-processing steps typically required in traditional machining to remove rough edges or burrs.
