Unique Rolling Mechanism
NISSEI’s innovative, horizontal 3-die form rolling system provides both an appropriate workpiece positioning during rolling and easy handling of the workpiece.
Self Centering Design
Three horizontally positioned and rotating dies accurately center the workpieces and produce uniform threads job after job without indexing the workpiece center.
Easy Set up
By positioning with the graduations on the scroll ring, all the dies will be fixed simultaneously. So you can set up in an extremely short time.
Rolling pressure is transmitted to the die holders through the hydraulic cylinder or the cam system. Each of the three roller dies performs with the same rolling pressure. The hydraulic type machine allows step-less rolling conditions.
Wide Variation of Workpieces
Our optional die holders accommodate an extremely wide variation of workpieces.
