FENN - Rotary Swagers

 During rotary swaging, forming dies back by hammer blocks revolve around the workpiece. As the spindle revolves, centrifugal force throws the hammers and dies outwards against a series of rollers surrounding the spindle. Each time the hammer blocks strike diametrically opposed rolled, they are driven inward – causing the die halves to close and compress the metal being swaged.​ ​Examples include cartridge heaters, hypodermic tubing, piping, armaments, and logging industry applications.
