Lead Screw
A lead screw is the part of a machine tool that transmits feed or movement over long distances by means of a thread – e.g. in clamping devices.
Relevance:
- Precise feed and guidance.
- Can be designed with a trapezoidal thread profile or other robust thread forms.
Practical example:
A vice in a workbench uses a lead screw to securely draw the jaws together and hold the workpiece firmly.
