CNC (Computer Numerical Control) milling is a subtractive manufacturing process that uses rotating multi-point cutting tools to remove material from a workpiece. Unlike turning, milling is ideal for producing complex geometries, flat surfaces, slots, pockets, and 3D contours. CNC milling manual machines are programmed to move the tool along multiple axes (e.g., 3-axis, 5-axis), enabling precise control over intricate designs. It is widely used in industries such as automotive, aerospace, and mold-making.
