CNC milled parts are components produced using computer numerical control (CNC) milling machines, a technology that automates the process of cutting and shaping materials based on precise digital instructions. This method involves the use of rotating cutting tools to remove material from a solid block or sheet, creating parts with high accuracy and consistency. CNC milling is a versatile technique that can work with a wide range of materials, including metals, plastics, and composites, making it applicable across various industries such as aerospace, automotive, and electronics.
