A “Computerized Numerical Control” machine, or CNC machine, is a machine that use, as the name suggests, a computerized numerical control. Initially used for precision machining, these machines are used in all fields of mechanics; among the most common are turning machines, boring and milling machines, welding machines etc.
The reasons why they are preferred to manual machines are as follows:
- significant reduction in processing times
- precision in the repetition of the various operations
- reduction in unit costs
- uniform and superior quality
When properly installed and equipped, they allow to obtain identical pieces within a tolerance of one micron.
The most technologically advanced versions have swiveling interchangeable heads, which allow to work a piece by tilting the tool with respect to the worktable, and can have from two to five axes, allowing not only to move in the X, Y and Z axes, but also to work with inclination and possible rotation.
