What’s the difference between CNC milling and CNC drilling?

CNC milling and CNC drilling are, as the names suggest, both types of computer numerically-controlled machining services. Both processes use a rotating cutting bit, the speed and rotation pattern of which is determined by information entered into the computer.  However, CNC milling differs from drilling because the cutting tool on a mill is able to move along a number of axes, enabling the CNC milling machine to create a range of shapes, slots, and holes. The work piece can also be moved across the machine in a variety of ways, allowing us to achieve very versatile results. Drilling is primarily for simple holes.
