Hydraulic Thread and Form Rolling Machine

Standard Equipment:

• Compact design
• Fabricated steel frame
• Versatile for all type of works
• Manual & Automatic cycles
• Range of cycle times
• Extended universal joint provides smooth operation for bib angle of work piece.
• Over sized coolant tank for superior cooling effects.
• Low pressure hydraulic power pack to ensure to low heat & minimum maintenance.
• “T” type and accurately ground slide assures that jumping and vibration will not happen during rolling.
• Centralized lubrication of all important moving parts.

Thread rolling is a chipless cold forming process. A plain cylindrical blank, with a diameter part way between the major and minor diameters of the finished thread, is rotated and squeezed between cylindrical type hardened steel dies whose working surface are the reverse of the thread form to be produced. The threads of the die penetrate the surface of the black as it rolls between them, displacing material to form the roots of the threads, and forcing the displayed material readily outward to form the crests. Unlike other threading process, no material is wasted.

Most threads are rolled by the in-feed method in which the entire thread length is formed simultaneously without axial movement of the part. Threads that is too long to be produced by the in-feed method can, however, be rolled by a thru feed method on these type of machine.
