CNC milling machine

The machines CNC (computer numerical control in English), which until the year eighty were only used for high-precision, are now very common and used in almost every field of engineering. 

The technology of CNC machines has covered a bit 'all branches of mechanics; CNC machines are the most common hydraulic press brakes, punching machines, lathes, milling machines, welders and sheet metal cutting machines (laser, oxyfuel, plasma, waterjet, etc..). They represent the evolution of NC machines, because they allow the direct numerical control from an external computer (CNC).
