serraggi

Serraggi is the plural form of serraggio, an Italian noun that denotes either the act of tightening or the devices used to clamp or secure a workpiece. The term derives from serrare, to tighten or close, which in turn comes from Latin serrare.

In manufacturing and machining, serraggi are essential to fix parts during operations such as milling, turning, and drilling. They encompass a range of clamping devices, including vises, chucks, collets, and fixture clamps. Hydraulic and pneumatic serraggi provide high clamping force and repeatability, allowing quick release when the operation is finished. The choice of serraggio affects positional accuracy, surface finish, and dimensional tolerance; improper serraggio can lead to movement, chatter, or deformation of the workpiece.

Serraggi also appear in discussions of fixtures and tooling setups, where the term may refer to the collective clamps used to secure a workpiece. In more general Italian usage, serraggio can describe the act of tightening screws or bolts, though that sense is often conveyed by serratura or serrare in everyday language.

The term serraggi is most commonly encountered in engineering, manufacturing, and technical documentation. It is less frequent outside technical contexts, and while it can appear as a surname in some cases, it is not widely documented as a figure of public life.
