What Is CNC Machining?
CNC (Computer Numerical Control) machining uses programmed cutting tools to remove material from metal stock. It includes milling, turning, drilling, tapping, threading, and boring. CNC machining is ideal for parts with complex geometries, tight tolerances, and excellent surface finishes.
