Metal engraving achieves the purpose of beautifying and decorating metal by engraving various patterns and characters on the metal surface, and is mainly used for decoration, commemoration, gifts and promotion.

Most metal engraving is done using 3-axis CNC machining, while for products with high precision requirements, HME Machining utilizes 4-axis CNC machining. Common metal materials with good machinability and corrosion resistance include brass, copper, aluminum, iron and stainless steel, which are the most commonly used materials. Plating provides a variety of colors and textures for metal engraving, while processes such as wire drawing and polishing can further improve the quality and appearance of the metal surface. The final product boasts a surface finish of 10 microns and the surface tolerance of ±25 microns.
