The purpose of function compounding is to further improve the production efficiency of the machine tool and minimize the time used for non machining assistance. Through the combination of functions, the use scope of the machine tool can be expanded, the efficiency can be improved, and one machine can be used for multiple purposes and one machine can have multiple functions. That is, a CNC lathe can realize both turning and milling functions; Or in the milling machine tool can also achieve grinding.

On the lathe, drills, reamers, taps, dies and knurling tools can also be used for corresponding processing. The function of the lathe is to cut various rotating surfaces of different sizes, shapes and helices.
