The advertising engraving knife is the core execution component of the CNC advertising engraving machine, with its primary function being the precise cutting, engraving, and shaping of various advertising decorative materials. It efficiently and accurately transforms vector graphics designed on computers into physical objects.

By quickly switching between cutting tips of different shapes and sizes (such as flat-bottom tips, V-shaped tips, and ball-end tips), it can perform three core machining functions: first, cutting—precisely shaping acrylic letters and signage; second, engraving—carving graphics and textures onto the surface; and third, drilling and 3D engraving/milling—achieving three-dimensional forms. The primary materials processed include acrylic, duochrome panels, wood, aluminum-plastic panels, and more.

With its high precision and efficiency, it has become an indispensable key production tool in the advertising signage, exhibition display, and handicraft manufacturing industries, directly determining the fine details and production speed of the final products.
