CNC turning involves machining the internal and external surfaces of components that are shaped like solids of revolution, usually cylinders or tubes. Besides milling, this method is an example of modern machining used on a large scale today, allowing for increased efficiency and automation of production processes. Thanks to the computer control of the lathes, it is possible to quickly program even very complex shapes, impossible to obtain in conventional machine tools.

After the turning process is completed, further machining on CNC machines is possible, as well as heat treatment, electroplating and many other activities included in the production of the finished detail.
