An engraving machine is a tool used to carve designs or text onto various materials, such as metal, wood, glass, or plastic. These machines can operate manually or automatically, with some models using computer numerical control (CNC) technology for precise and intricate designs. Engraving machines are commonly used in industries like manufacturing, jewelry making, and sign production. The process of engraving involves removing material from the surface to create a permanent mark. Different types of engraving machines include laser engravers, rotary engravers, and diamond-tipped engravers. Each type has its own advantages, depending on the material and the desired outcome.
