Si tratta di un tipo di rifinitura su metallo

Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helical toolpath by moving more or less linearly while the workpiece rotates. The tool's axes of movement may be literally a straight line, or they may be along some set of curves or angles, but they are essentially linear (in the nonmathematical sense). Usually the term "turning" is reserved for the generation of external surfaces by this cutting action, whereas this same essential cutting action when applied to internal surfaces (that is, holes, of one kind or another) is called "boring".

The first generation of osseointegrated implants had a relatively smooth machined surface
(Branemark et al. 1969).

******The machined implant surface is solely turned and considered to be minimally rough (Figure 1).******
