CNC (computer numerical control) machines are used for the automated precision machining of a wide range of materials, such as metal, plastic, wood, foam, and composites. They are used in industries such as automotive, aerospace, defense, electronics, medical devices, and more. CNC machines are able to perform complex machining operations, including milling, turning, drilling, routing, and grinding, with high accuracy and repeatability. They are used to produce a wide variety of components, parts, and products, ranging from simple to highly complex designs. The use of CNC machines allows for increased productivity, efficiency, and quality in manufacturing processes.
