CNC (Computer Numerical Control) is a modern machining method use to perform a wide range of machining tasks on a variety of metal and plastic materials. The primary advantage of CNC machining is that it allows for greatly improved accuracy, efficiency, productivity and safety over other forms of metalworking equipment. Virtually every piece of metalworking equipment is available in the CNC – lathes, drills, milling machines, routers, turret punches, grinders and other high-powered cutting devices.
