Milling is one of the typical processes carried out by modern CNC machines, ideal for the production of prototypes or custom designed elements. Due to the high precision it can be used as secondary processing on semi-finished products obtained with a different process. This is the most expensive of all types of machinery because it uses a computer system that does all the work. Being an automated system, it requires minimal human intervention. The operator inserts the instructions into the computer controlling the machine, in order to define the geometry of the workpiece and the path of the tool; subsequently it limits itself to control the machining, intervening in case of failures.
All this leads to a clear reduction in working time and higher productivity, which is not without benefits from an industrial and business point of view. The usefulness of these CNC milling machines is essentially limited to professional use.
