The Development History of 3DV-Type Blades

The 3D V-tool is a specialized three-dimensional forming tool designed for CNC engraving machines, primarily used for three-dimensional relief, chamfering, and curved surface engraving on materials such as wood and acrylic. It represents an upgraded iteration of traditional flat engraving tools. Early engraving processes relied solely on flat-bottomed pointed tools and standard V-tools, which could only achieve flat-line engraving and simple chamfering. These tools were incapable of creating three-dimensional curved surfaces or deep-to-shallow gradient 3D designs, resulting in limited processing styles, poor precision, and an inability to meet the demands of three-dimensional engraving for cultural and creative products or furniture decoration.
In the early 21st century, as CNC engraving equipment became widespread in China, the art of 3D carving emerged, giving rise to the first generation of 3D V-type knives. These tools featured arc-shaped, gradually tapered cutting edges, enabling the formation of three-dimensional surfaces in a single pass and addressing the issues of layered processing and rough textures associated with traditional tools. Early versions were primarily made of high-speed steel, offering high cost performance but being prone to wear. Later, through technological iterations, carbide 3D V-type knives gradually gained popularity, featuring higher concentricity, smoother cutting, and reduced risks of chipping or material burning. Today, these knives have become essential tools for woodworking relief and advertising engraving, compatible with various non-metallic materials and widely used in fields such as cultural artifacts, home decoration, and advertising production.
