Feed Screw
Feed Screws are engineered for transforming feed screw rotational motion into screw linear motion. Used in different fields, beginning with high precision machines to swing doors mechanisms.
As a rule, feed screw thread profile is trapeziform; metric or special is less often. Buttress threads are also used.
Feed Screws, engineered for special conditions, are manufactured of nitrided, martensitic, heat-resisting, high-speed and other types of steel.
