What is the difference between NC and CNC machining?
NC (Numerical Control) machining uses pre-programmed punch cards or fixed instructions to control machine movements, while CNC (Computer Numerical Control) machining uses dynamic computer software to control and adjust operations in real time. CNC offers significantly greater precision, flexibility, and repeatability—critical advantages for medical device components requiring tolerances as tight as ±.0002".
