CNC (computer numerical control) cutting sheets are sheets of metal or other materials that are cut using a CNC machine. A CNC machine is a type of machine that is programmed to cut or shape materials using a computer. CNC cutting sheets are used in a variety of industries, including manufacturing, automotive, aerospace, and construction, to produce precise and consistent cuts in materials such as steel, aluminum, brass, and plastic. CNC cutting sheets can be cut using a variety of methods, including laser cutting, plasma cutting, and waterjet cutting. The specific method used depends on the type and thickness of the material being cut, as well as the desired finish and precision of the cuts. CNC cutting sheets are used to create a wide range of products, from small parts and components to large structures and assemblies. They are highly accurate and efficient, and can be used to produce complex shapes and patterns with a high level of precision.
