CNC (computer numerical control) milling machines use a CAD (computer-aided design) program to maximize precision and accuracy in milling tasks. These machines use rotary cutting tools to remove material from workpieces to create parts with complex shapes and features. They have an adjustable table that holds a workpiece. The table moves along multiple axes and precisely positions the workpiece against the cutting tool. CNC milling machines complete milling operations faster and more accurately than manual milling machines.
